Subleasing an Aircraft: What Lessors Allow and What You Must Do First
You can sublease a leased aircraft only if your lease allows it, and most leases require the lessor's prior written consent. Lessors typically keep the original lessee liable, so you remain responsible for rent and return conditions even after the aircraft goes to a sublessee. On top of the contract, FAA rules on truth-in-leasing and operational control still apply to the new arrangement.
Key takeaways
- Read the assignment and sublease clause first: without the lessor's written consent, a sublease is usually a default.
- Expect the original lessee to remain fully liable for rent, maintenance and return conditions after subleasing.
- A sublease cannot give the sublessee more rights than the head lease gives you, and it is subordinate to it.
- For covered large aircraft, 14 CFR 91.23 truth-in-leasing requirements apply to a lease, and the party with operational control must be named.
- If crew is supplied, the arrangement can become a wet lease that needs the right FAA certificate. Get aviation counsel to review before signing.
Can you sublease an aircraft you lease?
Only if your lease says you can. Under a lease, the lessor keeps title and you hold the right to possess and use the aircraft, which is why NBAA describes a lease as a transfer of an aircraft without transfer of title. A sublease passes some of that right to a third party, and most lessors want a say in who ends up with their aircraft. Expect a clause that bars subleasing without the lessor's prior written consent.
That makes the first step simple: pull out your lease and find the assignment and sublease clause. If it is silent, treat that as a no until aviation counsel tells you otherwise. For the wider picture of structures, see our aircraft leasing guide.
Why do operators sublease an aircraft?
Usually because the aircraft no longer fits the plan. Common triggers:
- Surplus capacity. A seasonal charter operator or flight school has an aircraft sitting idle for part of the year. See also our guide to leasing for dry and wet lease structures.
- Fleet changes. A new aircraft arrives before the old lease ends, and you want to offset the remaining rent.
- Demand shifts. A contract ends or a program is cut, and the lease has years left.
- Early exit. Subleasing can be cheaper than an early termination, though the lessor must agree to it.
What do lessors typically require before they consent?
Consent clauses vary, and lessors are not required to say yes unless the lease says consent cannot be unreasonably withheld. These are the conditions that commonly appear in aircraft lease drafting; your lease controls.
| Lessor concern | What it usually asks for |
|---|---|
| Who gets the aircraft | Approval of the sublessee, sometimes limited to certificated operators with sound financials |
| Liability | The original lessee stays primarily liable for rent and all lease duties |
| Priority | The sublease is subordinate to the head lease and ends if the head lease ends |
| Default | No existing default under the head lease when you ask |
| Use and location | Same permitted use, base and insurance standards as the head lease |
| No further transfer | No sub-subleasing, and consent to one sublease is not consent to the next |
| Costs | You pay the lessor's legal and review costs |
| Financier consent | Approval from the lessor's lender if the aircraft is financed |
Lessors care because the aircraft is their collateral and their residual-value bet. How well a sublessee maintains and records the aircraft affects what the lessor gets back; we cover that in what operators must hand back and in why lenders care about residual values.
Which FAA rules apply when you sublease?
The contract is only half the job. Two FAA concepts matter most.
Truth-in-leasing. Under 14 CFR 91.23, a lease of a U.S.-registered large civil aircraft must be in writing and include a clause, in large print directly above the signatures, that identifies the regulations under which the aircraft was maintained and inspected in the previous 12 months, names the party responsible for operational control, and certifies that party understands its responsibilities. The lessee must mail a copy to the FAA Aircraft Registration Branch within 24 hours of signing, carry a copy on board, and notify the responsible Flight Standards office at least 48 hours before the first flight under the agreement, unless that office authorizes otherwise. The rule has exceptions, for example when the party receiving the aircraft holds a Part 121, 125, 135 or 141 certificate or is a foreign air carrier. Whether a particular sublease is covered is a question for aviation counsel.
Operational control. The FAA defines operational control of a flight as the exercise of authority over initiating, conducting or terminating the flight. In a dry lease, the lessee has it. NBAA notes that under a wet lease, where at least one crew member is provided, the lessor maintains operational control, and without an exemption such as a time-sharing agreement or an option under FAR 91.501, a wet lease requires an FAA commercial operating certificate. Our wet vs dry lease guide explains the difference in detail.
The practical lesson: if you sublease and also supply the pilots, you may have turned a simple dry sublease into a wet arrangement with certification consequences. FAA Advisory Circular 91-37B, Truth in Leasing, is the FAA's guidance on how these agreements are reviewed.
How do you ask a lessor to approve a sublease?
Treat it as a deal package, not a phone call. A clean request shortens review.
- Read the clause. Note the consent standard, any notice period and any limits on sublessee type.
- Vet the sublessee. Collect certificates, financial statements, insurance evidence and references.
- Draft the sublease. Mirror the head lease: same maintenance standards, records, insurance and return conditions, plus the truth-in-leasing clause if it applies.
- Send the package. Include the draft sublease, sublessee information and your plan for the end of the term.
- Allow for the financier. If the lessor's lender must consent, that adds time.
- Get consent in writing. A signed consent that names the sublessee and term protects you if relations sour.
- Complete FAA steps. File and notify as 14 CFR 91.23 requires, if it applies.
What does a sublease look like in numbers?
The figures below are hypothetical and for illustration only. They show why the spread is rarely the whole story.
In this example the spread looks positive, yet one month of delay and the consent costs turn it negative. Even so, the sublease may still beat leaving the aircraft idle, because without it you would pay the full $18,000 a month with nothing coming in. Compare the real alternatives, including an early termination, using the lease vs finance calculator, and check how the cost flows into your overall fleet plan with the aircraft loan calculator if you are weighing a purchase instead.
What are the main risks of subleasing?
- Default under the head lease. Subleasing without consent can put you in default, with remedies that may include repossession.
- Sublessee damage or missing records. You still owe the lessor the aircraft in return condition. Require the sublessee to meet the same standards and keep logs.
- Insurance gaps. Confirm the lessor and any lender remain named on the policy and that the sublessee's use fits the coverage.
- Regulatory missteps. Missing a required truth-in-leasing step, or blurring who has operational control, can create FAA exposure.
- Title and lien issues. Interests tied to the aircraft can be recorded; see how title, liens and escrow work and the International Registry explainer.
What are the alternatives to subleasing?
If the lessor says no, or the numbers do not work, there are other routes: negotiate an early termination or buyout, ask the lessor to re-lease the aircraft and release you, or use a time-sharing or interchange arrangement for short-term use where the rules allow. Each has its own regulatory limits, so confirm with counsel. If you are already weighing structure changes, our guides to operating vs finance leases and to the finance lease structure show how terms differ at the outset.
What should you do before you sublease?
Do these in order: read the clause, ask for consent in writing, vet the sublessee, mirror the head lease, handle the FAA steps and keep your return-condition plan intact. This article is general information, not legal advice; the right answer depends on your lease and aircraft, so involve aviation counsel and your insurance broker before signing.

Frequently asked questions
Can I sublease an aircraft I lease?
Only if the lease permits it. Most aircraft leases require the lessor's prior written consent, and some limit subleases to named types of operators. Subleasing without consent is commonly a lease default, so check the clause before you market the aircraft.
Do I stay responsible after I sublease the aircraft?
Usually yes. Lessors typically require the original lessee to remain primarily liable for rent, insurance, maintenance and return conditions, with the sublessee's obligations layered underneath. Confirm this in your lease.
Does the lender or lessor's financier have to consent too?
Often. If the lessor financed the aircraft, its lender may have its own consent right over the aircraft's possession and use, so the lessor may need to ask for it. Build that time into your plan.
Does a sublease need a truth-in-leasing clause?
For a U.S.-registered large civil aircraft, 14 CFR 91.23 requires a written lease with a truth-in-leasing clause, with specific exceptions. Whether your sublease is covered depends on the aircraft and the parties, so ask aviation counsel.
Is subleasing the same as a wet lease?
No. Subleasing describes the contract chain, while wet and dry describe whether crew is supplied. A sublease can be dry or wet, and a wet arrangement brings FAA operational control and certification questions.
