Over 9,000 U.S. Business Jets Locked Out of Bank Financing Due to Age Policies, Analysis Finds

The average business jet in the U.S. fleet is approximately 18 years old, a figure cited by both JETNET and Airbus Corporate Jets. Most bank aviation lending programs cap airframe age at 15 years at loan maturity, a threshold that Secured Research analysis of the U.S. registry found excludes more than 60% of active U.S. business jets, representing over 9,000 aircraft, from standard bank credit on age grounds alone, before any credit check or logbook review.

Secured Research's analysis of secondary-market transactions on airframes aged 15 to 25 years found that engine program enrollment and records quality explained more than three times as much variance in realized sale prices as chronological age. The analysis also found that well-maintained aircraft in the 15-to-25-year band exhibited materially lower valuation volatility through market cycles than aircraft under 10 years old. New and nearly-new business jets typically depreciate at 8–12% annually in early years, and by year 15 the depreciation curve flattens to low single digits.

Owners of aircraft over 15 years old were nearly twice as likely to self-fund acquisitions as owners of newer aircraft, citing financing availability rather than preference as the reason. Brokers report that older but well-maintained aircraft spend more time on the market because financing is difficult to obtain, not because buyer demand is absent.

The mismatch traces back to the lending boom of the early 2000s, when OEMs were delivering more aircraft than they produce today and specialized aviation finance teams were common. The 2008 financial crisis disrupted those teams and drove banks toward standardized underwriting that a generalist credit committee could handle without aviation expertise.

Age limits became a proxy for judgment that banks no longer staff for: whether engines are on maintenance programs, whether records are complete back to birth, whether damage history is minor or material, and whether a type's support base remains intact.

This is a case of underwriting proxies outliving the conditions that justified them. A blunt age cutoff was adopted when banks lacked in-house aviation expertise to assess maintenance programs and records quality directly, and it has persisted even as data shows those factors, not calendar age, drive realized resale value and valuation stability.

The financing gap has a market-wide effect beyond individual owners: it thins the buyer pool for aircraft aged 15 to 25 years, which suppresses liquidity across entire vintage bands and pushes more owners toward self-funding by necessity rather than choice. That, in turn, keeps well-maintained older aircraft on the market longer despite adequate buyer demand.

Whether this changes depends on whether lenders rebuild the specialized underwriting capacity that lapsed after 2008 — teams able to price engine program enrollment, records completeness and damage history directly rather than through an age proxy. Until a lender demonstrates that shift at scale, the gap between fleet age and financeable age will keep shaping which aircraft trade easily and which sit.
