Redelivery readiness
Lease-return records checklist for redelivery
This checklist walks the records side of a lease return clause by clause, tying each redelivery condition to the AD status, life-limited part trace, shop-visit package, and release certificate that supports it. Work it before technical acceptance, while the outgoing operator still owns closure. You finish with a redelivery binder index, a marked-up condition list, and a short discrepancy register.
When this review is needed
- A redelivery date is set and the return conditions name a records standard the binder has to meet.
- The outgoing operator has offered the records and someone needs a structured pass before accepting.
- A half-life or full-life return is being negotiated and the LLP and shop-visit evidence drives the number.
- An aircraft is being prepared for return and the team wants gaps documented while the lessee still owns the fix.
The problem
Redelivery conditions are written as clauses, but the records arrive as binders and a tracking export that nobody has mapped back to those clauses. A condition can read as met because a status line says so, while the document that proves it was never filed. Once technical acceptance is signed, an unproven clause stops being the outgoing operator's problem and starts being the lessor's.
What gets reviewed
- Each redelivery condition clause matched to the record that proves it
- AD and Service Bulletin status against accomplishment evidence
- Life-limited part status with trace to the required origin
- Engine, APU, and landing-gear shop-visit packages and last-shop reports
- Release certificates for components installed during the lease term
- Outstanding deferrals and open work that the return conditions touch
Scope this review
Tell us the asset, the event, and the evidence in scope, and we will outline a focused first engagement.
Send a representative, redacted record set and we will scope the review.
What gets validated
- Every clause in the return conditions points to a named document in the binder index
- Open and closed ADs carry method-of-compliance evidence, not just a status-line entry
- LLP remaining life on the status list reconciles with the disk sheets and last shop report
- Components fitted during the lease show a valid release appropriate to the installation
- Outstanding deferrals against the aircraft are listed with a clause-by-clause resolution position
Evidence normally required
Common discrepancies
- A condition clause with no document behind it once the binder is indexed
- AD status carried forward from a tracking system without the underlying accomplishment record
- An LLP whose remaining life on the status list does not match its disk sheet
- A component swapped during the lease with the release certificate never filed
- A deferral that the return conditions require cleared but that remains open at handback
What is at stake
A clause accepted on a status line rather than a filed document leaves the lessor holding rework cost and a weaker position for the next lease. Reassembling evidence after the operator has demobilized is slower and more expensive than asking for it while the aircraft is still on the ground at return.
How the work runs
Index the conditions
List every redelivery clause and create a binder slot for the document that is supposed to prove it.
Match document to clause
Walk each clause and attach the AD, LLP, shop-visit, or release evidence that supports it, marking met, partial, or open.
Log the open items
Capture each unproven clause in a short discrepancy register with the responsible party and the document still owed.
Hand to acceptance
Pass the marked-up condition list and binder index to the acceptance decision while the outgoing operator can still close items.
What the buyer receives
- A redelivery binder index keyed to each return condition
- A marked-up condition list showing met, partial, and open items
- A short discrepancy register with the responsible party for each open item
Who uses the output
- Asset managers deciding whether to sign technical acceptance
- Redelivery teams driving open clauses to closure with the outgoing operator
- Transaction stakeholders pricing what is still owed at return
How the work fits into the transaction or program
The checklist runs ahead of technical acceptance and feeds the redelivery binder. Where it surfaces deeper questions on an individual clause, the lease-return records audit takes those items further before sign-off.
Aircraft-specific considerations
Which clauses bite hardest depends on the type. A return on a twin-aisle leans on engine half-life and LLP evidence, while a regional turboprop return leans more on landing-gear overhaul and propeller records, so the binder index is built around the configuration in front of you.
Regulatory limits
The checklist confirms that records exist and line up with the return conditions. It does not make an airworthiness determination, settle a contractual dispute over the conditions, or guarantee that the receiving party will accept the return.
What this review does not cover
- Physical survey or borescope of the aircraft and engines
- Negotiating or interpreting the commercial terms of the lease
- Issuing any regulatory approval or airworthiness statement
Specific to this review
- Closure leverage is highest before technical acceptance, because once the return is signed the gap usually becomes the lessor's cost.
- A return condition written against records still fails if the binder cannot point to the specific document, even when the underlying work was done.
- Half-life and full-life return positions turn on engine and LLP evidence, so those packages are indexed first when value is contested.

Frequently asked questions
Does this checklist replace a full lease-return audit?
No. The checklist is the structured first pass against the conditions. Where a clause needs source-to-status reconciliation or a contested LLP position resolved, the lease-return records audit goes deeper before acceptance.
Can it be worked before the aircraft is on the ground?
Yes. The records and status evidence can be indexed against the conditions in advance, so only the items that depend on the final return state are left to confirm at handback.
