Part 91 Ownership with Limited Charter Offset:

The Owner Profile: Part 91 First, Charter Second

This page is for the owner whose aircraft is primarily theirs — flown under Part 91 for business trips, family travel, and the lifestyle the airplane was bought for — who then hands the keys to a Part 135 certificate holder for a hundred or two hundred hours a year of charter to blunt the fixed costs. That's a fundamentally different animal from a charter business that lets the owner fly occasionally, and lenders, insurers, and the IRS all treat the two differently.

The distinction that matters everywhere: who is primary. When your own Part 91 use dominates and charter is genuinely supplemental, you keep owner-grade financing, owner-adjacent insurance, and a defensible tax position. When charter hours start rivaling or exceeding your own, the aircraft becomes a working asset — and every one of those three frameworks reprices.

How Lenders Structure It

Underwriting starts from the business Part 91 baseline — 80 to 85 percent LTV with terms up to 20 years when the aircraft supports a legitimate business use — and then adjusts for the charter layer:

• Hour caps. Lender programs in our network generally cap charter activity around 400 hours annually. Inside a genuinely limited placement — say 100–200 hours against 150 of your own — most lenders treat the deal as owner-flown with a revenue kicker.
• LTV slides with charter share. As charter hours grow relative to owner hours, maximum LTV steps down, bottoming near 50 percent for charter-heavy operations, with minimum loan sizes applying.
• Disclosure is structural, not optional. The management agreement with your charter operator is a loan document. A charter placement discovered mid-underwriting — or worse, after closing — is the fastest way to lose a rate, a closing date, or a lender relationship. Disclosed upfront, it's a Tuesday.
• The operator matters. Lenders are more comfortable with established Part 135 certificate holders with real safety records and transparent owner reporting than with informal arrangements. Your operator choice is part of your credit file.

The Tax Layer: Two Sets of Books, One Aircraft

This is where limited-charter ownership rewards planning and punishes improvisation. The aircraft keeps its own logs — but your tax position is driven by use categorization, and every hour lands in a bucket: qualified business use, personal use, and charter service. The mix determines what you can depreciate, what you must recapture, and what income the charter revenue offsets.

• Bonus depreciation eligibility rides on qualified business use. The 100 percent bonus depreciation restored under the OBBBA requires the aircraft to clear qualified-business-use thresholds under the listed-property rules — and charter service and personal use both complicate that math in different ways. An aircraft that takes the full deduction in year one and then drifts below the use thresholds in a later year faces recapture. The bonus depreciation guide covers the placed-in-service mechanics and state-by-state conformity.
• Charter income and passive-activity rules. How charter revenue nets against ownership costs depends on how the activity is structured and your participation — territory where a one-hour conversation with an aviation tax advisor before closing is worth more than any page on the internet, this one included.
• Personal use has a price. Personal and entertainment use of a business aircraft triggers deduction disallowance calculations, and flight-by-flight logs are the only defensible way to run them.

Orientation, not advice. Aircraft tax outcomes are fact-specific — engage an aviation tax advisor before you close, not at filing season.

Making the Placement Work: what does charter offset actually recover?

Enter your fixed annual ownership costs and a realistic charter placement. The estimator shows how much of the fixed-cost burden charter revenue recovers — and flags when your hours approach the levels that change your financing structure.

Three practical rules from deals that worked: pick the operator before you pick the loan structure (their fleet needs, rate structure, and owner-use policies shape your real revenue); model conservative hours (operators quote optimistic placement — underwrite your budget at 60–70 percent of the pitch); and keep your own use protected in the management agreement (peak-season priority, minimum notice for charter bookings, and a clean exit clause).
