Truth-in-leasing in plain English.

§91.23 in three pages. What the regulation actually requires on a dry lease, what most operators get wrong, and the structure the industry has settled on for clean Part 91 use.

Most dry-lease problems aren't tax problems. They're §91.23 problems. The truth-in-leasing rule has been on the books for forty years, and it's the single regulation operators most commonly muddle when they're trying to be helpful by lending out an airplane.

Here's the rule in language the FAA actually used, then what it means when you're the one running the operation.

What §91.23 actually requires

For any lease of a U.S. civil aircraft of more than 12,500 lbs maximum certificated takeoff weight (and any time-share, interchange, or lease covering a large or turbojet aircraft), the parties must:

What "operational control" actually means

This is where most operators trip. The FAA defines operational control in §1.1: the exercise of authority over initiating, conducting, or terminating a flight. On a real dry lease, the lessee has operational control. Not the lessor. Not the management company. The lessee.

That's why a "dry lease" structured with the lessor providing the crew is — by FAA definition — a wet lease, and a wet lease that isn't being run under Part 135 is a regulatory problem.

If the same entity is providing both the aircraft and the pilot, that's not a dry lease. Call it whatever you want on paper; the FAA reads operational control through who's making the go/no-go call.

Frequently asked

What is FAR §91.23?
FAR §91.23 is the truth-in-leasing rule. For leases of large or turbojet U.S. civil aircraft, the parties must put the lease in writing, mail a signed copy to the FAA in Oklahoma City within 24 hours of execution, notify the FSDO 48 hours before first flight, carry the lease in the aircraft, and include a written truth-in-leasing clause naming who has operational control.
Does §91.23 apply to small piston aircraft?
No. §91.23 applies to U.S. civil aircraft over 12,500 lbs maximum certificated takeoff weight, plus any time-share, interchange, or lease covering a large or turbojet aircraft. Small piston dry leases are not subject to §91.23 specifically, though general lease and operational-control rules still apply.
What is operational control on a dry lease?
Operational control is defined in FAR §1.1 as the exercise of authority over initiating, conducting, or terminating a flight. On a real dry lease, the lessee has operational control — they make the go/no-go call. If the lessor is providing both the aircraft and the pilot, that is functionally a wet lease and likely a Part 135 issue.
Can the lessor provide the pilot on a dry lease?
No. If the same entity provides both the aircraft and the pilot, the FAA reads that as a wet lease regardless of what the document is titled. A Part 91 wet lease that is not run under Part 135 is a regulatory problem.
