01

Business Valuation & ESOP Advisory

Valuation Takes Flight performs business valuations for privately held aviation companies, including opinions of value for employee stock ownership plans (ESOPs) and their annual updates. We also value shares for stock buy-ins, buy-sell agreements, and internal ownership transfers among partners and family members. Each engagement is built around the value drivers specific to aviation operators, from airport leasehold terms to fleet residuals to FAA certificate standing.

02

Insurance Appraisal & Replacement Cost Studies

Replacement cost analysis and insurance-to-value studies for hangar owners, lenders, and carriers. Helps ensure adequate coverage, supports loss adjustment positions, and reviews insurance schedules at renewal. Delivered as cost consulting, not as a USPAP appraisal.

03

Hangar Rent Analysis

Fair market rent studies for airport hangars and ground leases. Valuation Takes Flight sets supportable rental rates using comparable lease evidence and a rate of return on underlying land value, the analysis airport sponsors and tenants rely on for rent resets, lease renewals, through the fence agreements, and FAA rate and rental structure compliance.

Concession & Airport Asset Diligence

An independent investment memo on a specific airport concession, secondary-airport stake, FBO, or MRO opportunity, written from the asset-valuation perspective the seller's deck won't give you.

Aviation PE Performance Verification & GIPS Advisory

Independent reviews of a fund's reported returns that account for the structural biases unique to hangar portfolios: appraisal smoothing, IRR manipulation, lease-term amortization distortion, and GP-LP information asymmetry. We serve LPs, GPs preparing for institutional raises, and pension funds evaluating aviation infrastructure allocations.

The Only Indexes of Their Kind

Aviation Business Value Benchmarks

Most aviation market data tracks aircraft. Our indexes track the companies that maintain, fly, and service them, built entirely from public data and published each quarter. The read is reported by segment, so it applies whether you run an MRO, an FBO, a parts business, or a flight school.

PABVI · Private Aviation Business Value Index
106.5
▲ +6.5% vs 2020 base
Mechanic Scarcity Index
114.0
▲ Labor tightening, about 14% above 2020

The story this quarter is the maintenance crunch. Roughly 70% of the pre-owned business-jet fleet for sale is now 16 years or older, and the certificated mechanic workforce is aging toward retirement. The scarcity index sits about 14% above its 2020 level, which is durable pricing power for MRO and repair-station owners and the single biggest driver of the business-value index this quarter.

MRO / Repair StationsScarcity is lifting margins and multiples.
FBO / CharterValues steady as flight activity normalizes.
Parts / AvionicsAftermarket demand keeps multiples firm.
