Aircraft hangar valuation and airport property valuation disputes rarely make national headlines, but for hangar owners, FBO operators, airport sponsors, assessors, and the litigators who represent them, the last five years have produced a remarkable run of precedent. State supreme courts have redrawn the lines on hangar property tax exemptions and possessory interest taxation. Federal and state courts have priced avigation easements, de facto takings, and hangar lease reversion clauses. And the FAA's Part 16 docket has become the busiest forum in the country for fights over fair market hangar rents at federally obligated airports.
This log indexes the notable decisions identified from January 2021 through July 2026, each with the citation, the forum, the decision date, a plain summary of the valuation issue, and a link to the primary source. Every entry also carries Clay's Take, a short read on what the ruling means for how you value a hangar.

2026
Half a year in, 2026 has already produced a Pennsylvania Supreme Court ruling in a nine-figure airport condemnation, a Colorado decision restructuring how FBO leaseholds are assessed, a builder's risk fight over the fatal Boise hangar collapse, and a Missouri Supreme Court decision blessing a special airport valuation statute.
In re Condemnation by the City of Philadelphia of the Airport Business Center
The largest airport condemnation valuation fight in the country. Philadelphia condemned eight parcels, roughly 140 acres known as the Airport Business Center in Tinicum Township, for Philadelphia International Airport expansion, and a board of viewers awarded the landowners more than 139 million dollars on a highest and best use as a privately owned air-cargo facility integrated with the airport. The city attacked that theory as financially infeasible. The Pennsylvania Supreme Court held the trial court's preliminary rulings were non-final under Section 518(1) of the Eminent Domain Code, because highest and best use is a mixed question of fact and law that must be resolved at a de novo jury trial rather than on interlocutory appeal.
Clay's Take: The whole ballgame in an airport taking is highest and best use, and this award proves it, because an air-cargo integration premium pushed the number past 139 million dollars. When I value land near an expanding airport, I test whether the market would actually pay for integration with airport operations, because that premium can dwarf the raw dirt value.
Sheltair Denver, LLC v. Jefferson County Board of Equalization
How should an FBO's hangars, terminal, and fuel farm on leased county airport land be assessed? Sheltair built the improvements at Rocky Mountain Metropolitan Airport under a 2018 ground lease providing that the improvements become permanently attached, with the county able to take title at termination without compensation. For tax year 2023 Jefferson County issued two assessments, one on the possessory interest in the land and another on the improvements. The Court of Appeals confirmed Sheltair holds a taxable possessory interest in both land and improvements, rejecting the county's theory that the FBO owned the buildings in fee, but reversed the stacked assessments. Colorado's unit assessment rule requires a single combined assessment of the possessory interest, and the court remanded for a unified valuation.
Clay's Take: This is now my starting point for valuing FBO and hangar leaseholds in Colorado. You assess the possessory interest as one combined unit, not land plus buildings stacked on top of each other, or the tenant ends up overtaxed. Getting the assessment structure right is often worth more to a hangar owner than arguing the number itself.
Big D Builders, Inc. v. American Zurich Insurance Co.
Coverage litigation born of the fatal January 2024 collapse of a 39,000 square foot airplane hangar under construction at Boise Airport. The general contractor's builder's risk policy provided up to 6.3 million dollars of coverage per structure. Zurich accepted most of the collapse loss but refused to pay for footings and columns installed before the policy's inception date, invoking a clause keyed to the percentage of total estimated completed value finished pre-inception. The court granted the contractor partial summary judgment, holding the policy's completed-value language tied coverage to the whole hangar project, pre-inception foundations included, and construing any ambiguity against the insurer.
Clay's Take: Hangars under construction are insured on completed value, and this case shows how much rides on where the policy draws the pre-inception line. When I price a partially built hangar for a loss, I value the whole structure as one project, foundations included, and I read the completed-value clause before I accept any depreciation the carrier wants to apply.
Cox v. Grady Hotel Investments, LLC
A rare state supreme court ruling on a special statutory valuation methodology for on-airport commercial property. The Platte County assessor valued the Marriott hotel on leased land at Kansas City International Airport at 11.2 million dollars, but the State Tax Commission cut it to 6.1 million under Mo. Rev. Stat. section 137.115.1, which requires deducting new construction and improvement costs from fair market value for certain airport properties. The assessor and a school district argued the statute created an unconstitutional de facto exemption. The Missouri Supreme Court affirmed the reduced value, upholding the statute and sharply limiting the challengers' standing.
Clay's Take: A special valuation statute like Missouri's can cut an on-airport property's taxable value nearly in half, and most appraisers do not even know these statutes exist. Before I value any leasehold improvement on airport land, I check whether a special valuation rule applies, because it can move the number more than any comparable sale ever will.
2025
2025 was the year hangar rent-setting went under the microscope. The FAA issued four major Part 16 determinations on hangar rents and hangar lease terms, Vermont's Supreme Court demanded transparent rent methodology from a state airport landlord, and courts priced everything from Growler-jet avigation easements to a de facto taking beside Detroit's city airport.
Bodeco, LLC v. City of Traverse City
The Michigan hangar tax case everyone is watching. Bodeco built a private aircraft hangar on land leased from the Northwestern Regional Airport Commission at Cherry Capital Airport and used it to store its owner's personal airplane. Traverse City assessed the hangar under Michigan's lessee-user tax (MCL 211.181), which taxes private for-profit users of tax-exempt public property, and the Michigan Tax Tribunal upheld the assessment. The Court of Appeals vacated, holding that the taxing authority, not the taxpayer, bears the burden of proving the lessee-user tax applies, and openly questioning whether a passive LLC storing a personal plane is a business conducted for profit at all. The Michigan Supreme Court has granted argument.
Clay's Take: This is the case I get asked about most. My read is simple: if you store your own plane in your own hangar and run no business from it, you should not be taxed as if you do, and now the city has to prove otherwise. For thousands of privately built hangars on leased municipal land, that burden shift is the difference between a taxable value and a defensible zero.
City of Ranger v. Ranger Airfield Maintenance Foundation
A cautionary tale about fair market value compliance in municipal airport leasing. A volunteer foundation held a long-term lease on the roughly 81-acre Ranger Airfield, including its historic 1928 hangar, and had raised more than 200,000 dollars for hangar restoration. An appraisal valued the land at 297,150 dollars plus 215,830 dollars in improvements. The court of appeals held the foundation failed to show its 2022 lease amendment conveyed the property for fair market value or satisfied the notice-and-bidding requirements of Texas Local Government Code section 272.001, so the amendment was not properly executed, governmental immunity applied, and the case was dismissed for lack of jurisdiction.
Clay's Take: In Texas, a municipal airport lease that skips the fair market value appraisal and the bidding steps can be void, which means the interest you thought you leased may not be yours at all. I treat section 272.001 compliance as a valuation issue, not just a legal one, because a defective lease can erase the value of everything built on it.
In re State Airport Hangar Lease Disputes (Winick et al., Appellants)
When Vermont's Agency of Transportation roughly doubled hangar ground rents at state airports, from about 12 to 25 cents per square foot, five tenants fought the increases up to the Vermont Supreme Court. The court held the leases' adjustment clause let the Agency consider current market value and maintenance costs, but reversed on statutory fairness review because the Agency's rent-setting methodology was neither transparent nor documented. Tenants plausibly argued the agency simply made up the number, and the court remanded for a complete record of how the rates were actually derived.
Clay's Take: A rent reset clause is only as strong as the appraisal behind it. This ruling tells airport landlords they cannot just pick a number and call it market, and it tells tenants that a poorly documented rent increase is beatable. When I set or challenge hangar ground rent, I document the market-value method step by step.
Bresciani & Aviation Partners, Inc. v. Puerto Rico Ports Authority
The companion case to Feliciano at San Juan's Isla Grande Airport, decided a month earlier. Bresciani spent about 200,000 dollars building a hangar under a four-year ground lease that expired in 2008, then occupied the hangar month to month at the original 2004 rate for 15 years while his written extension requests went unanswered, until the Ports Authority put him on a new six-year lease in 2023 that added a building rental rate on top of the ground rent. He alleged a violation of Grant Assurance 38 because the Authority never gave him a lease long enough to depreciate the hangar over the 30 to 39 years he argued GAAP and the IRS support. The Director found no violation, holding that the 15-year holdover effectively mirrored the duration of a long-term lease, that Bresciani's own request for only an 8-year extension undercut his amortization argument, and that the FAA will not rewrite lease terms, though the FAA again told the Authority to review its hangar leasing practices.
Clay's Take: The FAA counted fifteen years of month-to-month occupancy as amortization opportunity, so informal holdover time can substitute for the long-term lease a hangar builder never got. When I value a hangar sitting on an expired ground lease, that holdover period cuts both ways. It may have already returned the investment, and it leaves the sponsor free to add a building rate the day a new lease is finally signed.
Arnhold v. United States (NAS Whidbey Island Growler litigation)
Homeowners around Outlying Field Coupeville on Whidbey Island claim the Navy's 2019 expansion of EA-18G Growler field-carrier landing practice, which roughly quadrupled flight operations, took a second avigation easement over their properties through noise, vibration, and fumes. The government moved for partial summary judgment, attacking both timeliness and the plaintiffs' appraiser's diminution-in-value methodology as resting on hypothetical conditions. The Court of Federal Claims denied the motion, finding the claims timely under the Tucker Act's six-year window and sending genuine factual disputes over overflights and property valuation to trial.
Clay's Take: Noise takes value, and when flight operations intensify an owner can be owed for a second bite out of the same property. These cases are won or lost on the diminution study, so I build the before-and-after analysis on real market reactions, not hypothetical conditions, because that is what survives a methodology challenge.
Feliciano & Yellow Hangar, LLC v. Puerto Rico Ports Authority
Can a tenant who spends about 370,000 dollars building a hangar demand a lease long enough to recoup the investment? A hangar owner at San Juan's Isla Grande Airport alleged the Ports Authority violated Grant Assurances 22, 24, and 38 by issuing a retroactive 32,839 dollar lump-sum invoice, forcing a new lease under duress, and refusing a long-term lease sufficient to amortize his hangar. The FAA Director rejected every count and held that Grant Assurance 38 sets no minimum lease term, so nothing entitles a hangar builder to a 30 to 35 year amortization horizon, though the FAA did recommend the sponsor review its hangar leasing practices.
Clay's Take: Tenants assume a long lease is guaranteed so they can amortize a hangar they built, but the FAA just said no such right exists. A hangar's worth to its builder depends on remaining lease term, so if the sponsor can decline to extend, you value the improvement over the term you actually hold, not the term you hoped for.
Carroll County Regional Airport Runway Condemnation (Maryland)
A 3.5 million dollar lesson in avigation easement valuation. To extend the Carroll County Regional Airport runway from 5,100 to 5,500 feet, the county condemned about a third of an acre plus an airspace easement over an 80-acre hilltop residential property. The owners argued the runway approach and two decades of acquisition threats rendered the whole residence unmarketable despite the tiny physical take. The jury agreed, awarding 3.5 million dollars, five times the county's final pretrial offer of 700,000 dollars and roughly thirteen times its original 268,500 dollar offer. The county accepted the verdict, with FAA funds covering 90 percent of the award.
Clay's Take: A third of an acre produced a 3.5 million dollar verdict because the jury valued the whole property as impaired, not just the sliver taken. This is my standing reminder that severance damages under a runway approach can dwarf the physical take, and that sponsor appraisals routinely understate them. Trial-level only, so confirm the docket before you cite it.
Yarbrough v. Marion County Assessor
A small case with big practical value for hangar assessment appeals. The taxpayer challenged the 2024 to 2025 real market value of a metal aircraft hangar at Salem's airport, arguing the assessor's 95,190 dollar value, reduced to 84,210 dollars by the Property Value Appeals Board, ignored substantial physical obsolescence and disrepair. The Oregon Tax Court granted the assessor's motion to compel a site inspection of the hangar, with dismissal as the sanction for refusal, and declined to let the taxpayer impose deposition rules on questioning the county's appraiser.
Clay's Take: Condition drives hangar value, and this small case is a clinic on it. Physical depreciation and obsolescence are real deductions, but you have to let the appraiser inspect the building to prove them. When I value an older metal hangar, the walk-through is not optional, it is the evidence.
State ex rel. Boggs v. Cleveland
Homeowners outside Cleveland's city limits alleged that Cleveland Hopkins International Airport's runway expansions sent escalating overflights, noise, vibration, and fuel debris over their home, rendering it unlivable and unmarketable, and sought mandamus to force the city to commence appropriation proceedings after it refused their offer to buy an avigation easement. The Ohio Supreme Court held the Ohio Constitution's takings clause applies regardless of municipal boundaries, so out-of-city property owners can pursue inverse condemnation against the airport proprietor. Whether an avigation-easement taking occurred, and what it is worth, heads to trial on remand.
Clay's Take: Airport noise does not stop at the city line, and now neither does the airport's liability for it. For anyone valuing homes under a busy approach, this opens the door to inverse condemnation, and the real question becomes how much the overflights actually took out of market value.
Haney et al. v. County of Los Angeles
A landmark FAA determination tying hangar rents directly to fair market value appraisal quality. Users of five Los Angeles County general aviation airports (El Monte, Brackett Field, Compton, Whiteman, Fox Field) alleged the county rented hangars for nonaeronautical use below fair market value while charging aeronautical users above-market rates based on flawed consultant appraisals, with 24 percent of the county's 1,089 hangars sitting vacant. The Director found the county violated Grant Assurances 24 and 25, estimating at least 3.35 million dollars in forfeited revenue from 2019 to 2024, including roughly 442,655 dollars per year at El Monte alone.
Clay's Take: This determination makes appraisal quality the whole battle. If a sponsor rents hangars for nonaeronautical use below market while overcharging aeronautical users, that is revenue diversion, and a weak consultant appraisal is what exposes it. When I review sponsor hangar rates, the appraisal methodology is the first thing I take apart.
Smith, Kim Davidson Aviation & NBAA v. City of Santa Monica
The highest-profile hangar rate fight in the country. Tenants and NBAA challenged Santa Monica Airport's compensatory rate methodology for hangar, tie-down, and landing fees as the city steers toward closing the airport in 2028. The Director held that a compensatory methodology separating aeronautical from nonaeronautical revenue is not itself unlawful, but found Santa Monica violated Grant Assurance 25 by deliberately accumulating roughly 19.1 million dollars in nonaeronautical surplus intended for diversion to city coffers at closure, and ordered the fee structure revised within 30 days. The city has appealed to the Associate Administrator.
Clay's Take: This is the ceiling on how hard a sponsor can push hangar and tie-down rents. A compensatory method is fine, but stockpiling a nonaeronautical surplus to cash out at closure crosses the line. For tenants facing steep increases, the revenue-accumulation limit is the pressure point I would test first.
HRT Enterprises v. City of Detroit
Two decades of airport-expansion limbo, finally priced. HRT owned an 11.8-acre industrial parcel beside Coleman A. Young International (Detroit City) Airport while the city bought up surrounding land, closed access roads, imposed FAA height restrictions, tolerated blight, and even had HRT's contractors arrested for trespass, all without formally condemning. After two federal jury trials, with verdicts of 4.25 million dollars, remitted to 2,008,000 dollars, then 1,976,820 dollars with a jury-set taking date of January 1, 2009, the Sixth Circuit affirmed the de facto taking in full. A companion ruling vacated a 720,486 dollar fee award, holding that related state and bankruptcy proceedings are compensable but expert fees are not recoverable under section 1988 in section 1983 takings suits.
Clay's Take: When an airport slowly strangles a neighbor with buyouts, height limits, and blight, that is a taking even without a condemnation filing. The valuation twist is the taking date, because it fixes the market conditions you value against, and picking the right date can swing the award by millions, as it did here.
2024
The theme in 2024 was who keeps the value. Louisiana courts blocked a city from taking tenant-built hangars for free, Ohio's tax board exempted leased municipal hangars under a friendlier construction standard, and the FAA blessed a steep cost-recovery rent methodology at John Wayne Airport while striking down arbitrary rate gatekeeping in Hawaii.
South Pacific Flying Club v. Hawaii Department of Transportation
Hawaii DOT terminated a flying club's hangar permit at Honolulu's Daniel K. Inouye International Airport and conditioned eligibility for the discounted noncommercial hangar rate of 772 dollars a month on holding IRS 501(c)(3) or (c)(7) tax-exempt status, while restricting instructor and mechanic compensation. The FAA Director found the state in violation of Grant Assurance 22 on economic nondiscrimination, holding that gating access to a noncommercial hangar rate tier on arbitrary organizational-status proxies, rather than actual use, is unreasonable, and that the compensation restrictions contradicted FAA flying-club policy.
Clay's Take: Discounted hangar rates have to track how the space is actually used, not what tax box the tenant checks. For valuation, that means the rate tier a hangar qualifies for should follow its aeronautical use, and a sponsor cannot manufacture a higher rent by gatekeeping on paperwork.
Graftaire, LLC v. City of Shreveport
The hottest issue in general aviation hangar valuation, uncompensated lease reversion, meets the takings clause. Hangar owners who built private hangars on leased ground at Shreveport Downtown Airport sued when the city claimed their buildings under an improvement-reversion clause without paying a dime. The court of appeal affirmed a preliminary injunction against the city, holding that any waiver of constitutional just-compensation rights in the city's non-negotiable form leases was not knowing, voluntary, or intelligent given the city's monopoly position, and that the ambiguous reversion language could not transfer privately financed hangar value to the sponsor for free.
Clay's Take: Uncompensated reversion is the single biggest hidden risk in general aviation hangar value, and this court treats it as a probable unconstitutional taking. My view is that an owner does not lose the building's value for free just because a form lease says so, and as decades-old ground leases expire, this is the fight that decides who keeps the improvement value.
City of Middletown v. Harris (Middletown Regional Airport)
Ohio's Tax Commissioner denied a real property tax exemption for hangars at the City of Middletown's municipal airport because they were leased to private users. The Board of Tax Appeals reversed and granted the public-use exemption, notably applying the Ohio Supreme Court's Stingray Pressure Pumping fair-reading standard in place of the old rule strictly construing exemptions against the taxpayer. Leasing municipal hangars to private individuals, the Board held, does not by itself defeat the airport's public-purpose exemption.
Clay's Take: Leasing municipal hangars to private pilots no longer makes them automatically taxable, at least under Ohio's friendlier reading. That neutral construction standard can preserve an exemption, and for a municipal airport it directly changes the after-tax value of the whole hangar portfolio.
Southern California Pilots Association v. County of Orange (John Wayne Airport)
Pilots alleged John Wayne Airport's General Aviation Improvement Program, which eliminated 242 GA parking positions, plus tie-down and hangar rent increases claimed at 248 percent between 2017 and 2023, unjustly discriminated against small-aircraft owners. The FAA Director found no violation, holding the county's rate methodology, a 2018 cost-recovery study using land valuation, depreciated replacement value of buildings, and operating expenses, was reasonable, that both full-service FBOs paid identical ground rents, and that GA revenues of 10.7 million dollars against costs of 9 million dollars showed no discriminatory overcharging.
Clay's Take: This one cuts the other way and blesses a steep increase, because the county backed its rates with a real cost-recovery and depreciated-replacement-value study. The lesson for both sides is that a defensible appraisal wins, so when I set GA hangar and tie-down rates, this is the methodology I build on.
2023
A quieter year in volume, but 2023 produced Florida's most consequential airport tenant taxation ruling in decades and a bankruptcy confirmation battle decided by competing appraisals of a fly-in community's hangar development potential.
In re Heaven's Landing, LLC
A Chapter 11 confirmation fight decided by dueling appraisals of a private airport. Heaven's Landing, a residential fly-in community in the north Georgia mountains with a 5,000-foot concrete runway and 38 hangars, faced a secured lender owed over 3.7 million dollars that attacked plan feasibility. The bankruptcy court found Phase 1 alone worth 2,650,000 dollars, rejecting the lender's 1,700,000 dollar appraisal, and emphasized that future phases where airplane hangars could be built and sold could generate millions of dollars of profit. The court confirmed the plan, which paid creditors in full.
Clay's Take: In bankruptcy the appraisal is the case, and here the court credited future hangar buildout as real value rather than speculation. When I value a fly-in community or a phased hangar development, the income from hangars not yet built belongs in the analysis if the demand is genuinely there.
Hillsborough County Aviation Authority v. Henriquez (Tampa International Airport)
The defining Florida fight over taxing airport tenants. In 2019 the Hillsborough County Property Appraiser stripped longstanding ad valorem exemptions from about 15 aviation tenants, including airlines, cargo operators, fuelers, maintenance shops, and fixed-base operators, at Tampa International and three county general aviation airports, generating millions in surprise tax bills. After the tenants lost at trial, the Second DCA reversed, holding that tenant operations serving aviation or airport purposes on authority-owned airport land serve a governmental purpose and are exempt under Florida law. The Florida Supreme Court declined review in August 2024, ending the five-year fight in the tenants' favor.
Clay's Take: This is the ruling every Florida airport tenant assessment now starts from. If an operation serves an aviation or airport purpose, the leasehold can stay exempt, and that exemption is a direct line item in the property's value. I check governmental-purpose eligibility before I finalize any Florida hangar or FBO valuation.
2022
2022 delivered two sobering lessons for hangar interests, a takings claim defeated by the sponsor's contract rights in Texas and a proven federal taking worth exactly zero dollars for want of valuation evidence, plus the highest-profile hangar insurance valuation dispute of the window.
Metropolitan Nashville Airport Authority v. Affiliated FM Insurance Co.
When the March 2020 tornado tore through John C. Tune Airport, it destroyed dozens of hangars and left the Metropolitan Nashville Airport Authority and its property insurer tens of millions of dollars apart on the measure of loss, replacement cost value versus depreciated actual cash value for the destroyed hangar facilities. The Authority sued in state court and the insurer removed to federal court. The docket shows the fight centered on the ACV versus RCV valuation gap, and no merits opinion was ever published, indicating the case likely settled. It is indexed here as a documented valuation dispute, so verify the disposition on PACER before citing.
Clay's Take: This is the fight I see after every catastrophic hangar loss, replacement cost against actual cash value. The gap is enormous on older hangars, and it comes down to how you measure depreciation, so I frame that depreciation carefully, because tens of millions can ride on it.
City of Weslaco v. De Leon
An aircraft-maintenance operator leasing two hangars at Weslaco's Mid Valley Airport alleged the city took his property when it terminated his leases and cut off airport access. The court of appeals dismissed for lack of jurisdiction, holding the city acted on colorable contract rights under the lease, not its eminent-domain power, so no viable takings claim existed, and governmental immunity barred the contract and tort claims. No compensation analysis was ever reached.
Clay's Take: When a sponsor terminates a lease instead of condemning, the tenant's takings and valuation claims can die at the courthouse door. For a hangar tenant that means the lease terms, not the appraisal, decide whether you have anything left to value, so I read the termination and access clauses first.
Cully Corporation v. United States
A proven taking worth nothing. The Alaska Native village corporation for Point Lay held a reversionary interest in three former DEW-line buildings, including the Air Freight Terminal hangar at the Point Lay airstrip, that the Air Force clouded by repudiating a 2006 transfer. The court found a temporary taking from 2013 to 2022, then entered judgment for the government anyway, because fair-rental-value methodology did not fit a reversionary interest encumbered by a long-term lease, the owner's expert assumed enforcement efforts that never happened, and the government's expert showed the interest had negligible market value. The award was zero dollars.
Clay's Take: A proven taking still recovered nothing because the valuation evidence did not fit the interest. A reversionary or non-possessory interest in a hangar cannot be valued with a simple fair-rental approach, so match the method to the interest, or you win liability and lose the money.
2021
The window opens with two state supreme courts drawing opposite lessons on airport exemptions, Ohio protecting a university airfield full of private tenants and Wisconsin strictly enforcing a flight-count threshold, plus appellate rulings on hangar value in divorce and on whether reverted improvements reset airport rent.
In re Marriage of Morgan
How much is a hangar on leased municipal airport land worth in a divorce? The couple built an airplane hangar with roughly 60,000 dollars of marital funds on land held under a perpetual lease from the City of Cabool and rented it out for about 2,000 dollars a month. At dissolution, the husband's expert said 30,000 dollars and the wife said 100,000 dollars, based on the husband's own statements about construction cost. The trial court adopted 100,000 dollars and the court of appeals affirmed, holding the husband's substantial-evidence challenge failed because it ignored the evidence supporting the higher number.
Clay's Take: A hangar on leased airport land still has to be valued in a divorce, and here the court leaned on construction cost and the owner's own statements over a lowball expert. It is a useful reminder that an owner's admissions about what a hangar cost to build are powerful evidence of value, in or out of family court.
Southwest Airlines Co. v. Wisconsin Department of Revenue
Southwest sought Wisconsin's hub facility property tax exemption for its airline property at Milwaukee Mitchell International Airport after paying roughly 4.2 million dollars in property taxes for 2013 and 2014. The statute exempts carriers operating at least 45 departing flights each weekday. Southwest fell short on 6 days in 2013 and 91 days in 2014, and argued for averaging, at 46.28 flights per weekday, or for weather-and-holiday exceptions. The court refused, holding that each weekday means every weekday, with no exceptions and no averaging. The exemption was denied.
Clay's Take: Exemptions that hinge on an operational metric get read literally, so close does not count. For any airport property whose tax treatment depends on flight counts or similar triggers, I stress-test the numbers against the exact statutory threshold before I assume the exemption holds and price it into value.
O'Keeffe v. McClain (Ohio State University Airport)
Can a university airport stay tax-exempt when private tenants generate 85 percent of its revenue? A challenger attacked the exemption for Ohio State's 325-acre Don Scott Field, roughly 350,000 square feet of hangars, offices, classrooms, and labs, pointing to about 7.3 million dollars in annual revenue from private hangar and facility leases. The Ohio Supreme Court, by a 5 to 2 vote, upheld the exemption, holding that the airport's primary use supported OSU's educational mission, that operating a public airport itself qualifies under Ohio law, that secondary lease income does not defeat the exemption, and that no split-listing of leased portions was required.
Clay's Take: A public or institutional airport can stay exempt even when private hangar and FBO leases generate most of the revenue, as long as the primary use qualifies. For valuation that means secondary lease income does not automatically create a taxable value, which materially changes what the airport portfolio is worth after tax.
K.C. Air Cargo Services, Inc. v. City of Kansas City
Does reversion of tenant-built improvements reset airport rent to appraised fair market value? A cargo tenant built a 70,000-square-foot warehouse and half-million-square-foot apron on city land at Kansas City International under a 1986 lease. On renewal, the city demanded a fresh appraisal since it would then own both land and improvements. The court affirmed judgment for the tenant, holding that renewal on the same terms and conditions meant the existing CPI-based formula, a monthly rent of 6,934.70 dollars with increases capped at 2.5 percent, and that no reappraisal was permitted, reverted improvements or not.
Clay's Take: Whether reverted improvements reset rent to fresh market value comes down to the renewal clause wording, and here careful drafting beat the sponsor's appraisal expectations. When I value a long-term airport leasehold, I read the renewal and reversion language closely, because the rent formula it locks in can outweigh any market study.

The Director held that lease terms shorter than 30 to 35 years are not a violation, that the 30 to 35 year horizon in FAA Order 5190.6B is a best practice left to the sponsor's discretion, and that a tenant's bare claim that a term is too short to amortize a hangar investment is not enough to prove noncompliance. Both the Feliciano and Bresciani determinations above are built directly on it, and it now frames every fight over whether a hangar builder is entitled to a lease long enough to recoup the investment.
Rare Air Ltd., LLC v. Property Tax Administrator
A hangar built by a sublessee at Centennial Airport, at a cost of roughly 2.4 million dollars on tax-exempt airport land, could be assessed as a taxable possessory interest. The incidents of ownership the sublessee held, including exclusive use and the right to the income and improvements, supported taxing the hangar even though the underlying land was exempt. The leading modern statement of when a privately built hangar on public land becomes taxable, and a direct forerunner of Sheltair.
Nikolits v. Runway 5-23 Hangar Condominium Association, Inc.
The Florida hangar condominium case. Forty-one hangars at Boca Raton Airport, on state-owned land but leased through a condominium association to private aircraft owners, stayed exempt from ad valorem tax. The court held that the leasehold condominium form did not convert state-owned improvements into taxable private property, because the members leased only the airspace and the state still owned the land and hangars. The go-to authority whenever a hangar condominium structure meets a property appraiser, and a regular companion to Sebring and Williams in Florida briefs.
Sebring Airport Authority v. McIntyre
Florida's benchmark for narrowing the governmental-purpose exemption when public airport property is put to private, for-profit use. Courts apply it whenever a lessee claims that its use of airport land serves a governmental purpose and should escape ad valorem tax, and it frames the Hillsborough fight above.
Williams v. Jones
The origin of the governmental-governmental use test for taxing leasehold interests in public property. Nearly every airport and hangar exemption fight in Florida still runs through this decision.

About this log. Entries are compiled from state and federal court records, FAA Office of Airport Compliance determinations, state tax tribunals, and the legal and aviation press, and each is summarized in plain language for professionals evaluating hangar and airport real estate. Clay's Take is professional commentary, not a client opinion of value. This page is current awareness and general information. It is not legal, appraisal, or tax advice, it may not reflect the latest procedural posture of a pending matter, and it does not create an engagement. Where an entry notes that a citation or disposition is unverified, treat it as a lead, not a holding, and confirm it against the primary source before relying on it.
