Aircraft redelivery you run in conversation with seven agents — from 24 months out to the signed technical acceptance certificate
Every lease return handed back on its date, inside budget, with every gap priced.
See one case, screen by screen ↓Aircraft redelivery management runs a leased aircraft's return to the lessor — the lease return, or aircraft handback — from 24 months out to the signed technical acceptance certificate. In Aircraft Redelivery Management, seven agents quote every lease return condition, project the aircraft's state to the return date, price perform or compensate for each gap, check each other's numbers blind, chase back-to-birth records and draft every letter to the lessor. The lease technical manager asks them questions, decides and sends; the Head of Lease Management signs acceptance.

Every aircraft redelivery ends a lease the same way: the aircraft goes back in the condition the lease's return schedule describes — a fresh heavy check, engines and landing gear with a stated share of life left, life-limited parts above a floor, paint and cabin to the lessor's standard, every record back to birth — or the airline pays end of lease compensation where the lease allows it. Today a lease technical manager reads those conditions by hand from a lease PDF, its amendments and side letters, and works the rest in spreadsheets, e-mail and a records portal.
The risk sits in the gap between today and the return date. A landing gear or an engine that meets its half-life condition today can fail it on the day of return, and perform or compensate gets argued item by item in two spreadsheets, one on each side. Letters to the lessor make promises nobody tracks, and back-to-birth gaps turn up on the lessor's master issues list, when there is no time left to recover the record. Every month the return slips adds holdover rent.
Estimated split of the lease team's own days on one widebody lease return, by hand and with the solution. For scale, IBA puts the technical and records support for a first-lease narrowbody return at 120 man-days or more, and says a widebody may need more than double.
Seven agents read the lease, project the aircraft to its return date, price perform or compensate, check each other and draft every letter; the lease manager decides.
Corvane Airways' A330-300 N806CV, MSN 1797, goes back to Aldermoor Aviation Capital under lease LA-2017-0806 on Monday, May 17, 2027, at DEN. Here is Thursday, October 15, 2026, screen by screen in the working solution: what the agents did overnight, what Rachel asks them, what they show her, and what she decides — on N806CV and on the 737-800 whose engine shop visit threatens its return date.
Rachel owns the widebody returns. Her morning shows 9 active returns, 1 decision waiting, 2 promises due in 30 days and 12 open findings on N806CV, with what each agent did overnight: the condition agent projected 46 conditions, the cost agent priced the landing gear, the check agent recomputed it and the letters agent drafted the notice to the lessor. Beside it the redelivery agent's briefing, with numbered citations, and a box to ask it anything.
“Of 9 returns, one needs you today: N806CV's landing gear. … N523CV is the other one to watch: its engine shop visit runs 9 days past its return check.”
N806CV's return is one trail from May 17, 2025 to May 17, 2027, today marked at 214 days to go, with lanes for records, engines and APU, landing gear, airframe and cabin, and letters to the lessor. At its head the redelivery agent suggests compensating the gear. Rachel asks why the gear is short at return. The condition agent answers with the lease clause and the life sheet cited: 10 months left today, 3 on May 17, 2027, against the 60 the lease asks — and opens the decision for her.
“No overhaul fits before return without 6 more hangar days, so the cost agent priced both paths.”
Every condition in Schedule 6 is quoted from its clause and set against the aircraft's state today and on May 17, 2027: 35 meet at return, 5 are work to perform, 3 are compensated and 3 are records gaps. Engine 2 shows why the projection matters — 10,596 FH to restoration today, 7,900 FH at return, under the 9,000 the lease asks for.
The condition agent never marks a condition met without a record.
The decision screen shows the gear's life against the lease, the clause, and both paths line by line. Compensate: 57 months short × $21,063 a month, no hangar days added. Perform: a Westrail exchange shipset overhaul, removal and installation at DEN Hangar 6, freight and core return, the lessor's gear records review and 6 more hangar days. The check agent recomputed the formula from the lease text alone and agrees to the dollar; confidence 0.93.
Cost agent: “Compensating costs $451,409 less and keeps 6 hangar days; the lease gives us the option (¶3.4(b)).”
Rachel asks the cost agent to reprice with escalation on January 1. It comes back at $1,233,594. The check agent recomputes alone from ¶3.4(c), which escalates on each anniversary of the Delivery Date, and disagrees by $33,003. Compensate is greyed out until the figures agree; one click puts the price back on the lease's anniversary basis.
“Blocked: the check agent gets $1,200,591 from the lease; the figure on the card is $1,233,594. Nobody can decide until they agree.”
Rachel elects compensation under Schedule 6, ¶3.4(b), with reason code C1 — “Compensate — lower cost, lease allows it” — and her e-signature. Nothing goes to Aldermoor yet: the letters agent prepares L-07 for her to send. The forecast for N806CV is $5,905,259, $294,741 under its $6.2M budget; overhauling would have put it $156,668 over.
“Nothing goes to Aldermoor until you send the letter.”
The notice of election to Martin Kessler at Aldermoor quotes the clause, the months and the rate, and follows up letter L-05. Beside it, the letters agent's checks: the amount matches the return cost record, the clause and dates match the lease and the life sheet, it keeps promise P-05 — the gear position by Nov 13 — it is inside the lease deadline of Nov 18, and nothing internal is disclosed. Under $1.5M, the lease technical manager may send it herself; every promise in it goes on the trail, ours and Aldermoor's.
The letters agent never sends — a person signs every letter.
From the returns list Rachel opens N523CV, a 737-800 going back to Northwind Aircraft Finance on Mar 12, 2027. Engine 1's shop visit has a quoted 92-day turn time, so the engine comes back 9 days after the return check ends. The redelivery agent sets out two ways to keep the date — lease a spare engine for the return, about $148,000, or swap in Corvane spare ESN 896-412 — and suggests the lease, which the cost agent checked sits inside the $2.62M forecast and keeps the fleet's spare on the line. Rachel approves the lease with reason code E1, “Keep the return date”, and her e-signature; the letters agent drafts the engine-change notice to Northwind for her to sign.
“I suggest the lease — the cost agent checked it sits inside the $2.62M forecast, and it keeps the fleet's spare on the line.”
The return set is organized to ATA Spec 2500: 41,860 of 41,880 documents ready, 99.95%. Overnight the records agent found the signed card for F-102, the Jun 2025 repeat inspection under AD 2023-14-09, in the DEN paper archive and indexed it; it waits for Lucia to confirm. F-041, an APU impeller back-to-birth gap, is escalated to the repair shop's quality manager, with a fallback priced: a new impeller at $84,000, ordered by Jan 15, 2027.
The records agent never closes a gap by itself.
The acceptance checklist runs from every return condition met, performed or compensated, through the master issues list and the final records pack, to the technical acceptance certificate, the FAA registration cancellation under 14 CFR 47.41 with IDERA honored, the export certificate of airworthiness (FAA Form 8130-4) if the next registry is outside the US, and off-rent. Today three items block it; nobody can sign with an open item. When every item closes, on May 17, 2027, Daniel signs the certificate with Aldermoor.
“The redelivery agent checks this list every night; nobody can sign with an open item.”
The same lease return, seen by four of the people who carry it — what the last months of a lease looked like, and what they look like now.
Seven agents read the lease, project the aircraft to its return date, price perform or compensate, check each other and draft every letter; the lease manager decides.
Owns each return trail; re-plans it every night from hangar slots, shop turn times and promises; writes what is at risk at the head of the trail, proposes the ways to keep the return date and escalates.
Reads the lease, its schedules, amendments and side letters, and maps every return condition, compensation formula and date — each quoted from its clause.
Projects the aircraft's state on the return date from utilization, the maintenance forecast and LLP sheets, and compares it with every condition.
Prices perform against compensate for each gap from the lease formula, shop quotes, hangar days and holdover rent, and keeps the return cost record.
Recomputes every compensation and projection blind, from the raw lease and records.
Keeps the ATA Spec 2500 set, finds gaps against the return conditions, chases shops, archives and prior holders, prices fallbacks and drafts responses to findings.
Drafts letters to the lessor, extracts every promise both ways with its date, reminds before each one falls due, and checks each letter against the cost record and the lease.
Decides and sends; the Head of Lease Management co-signs over $1.5M and signs acceptance. The agents propose; a named person decides.
Every screen has the agents beside it. Ask a question or tell them what to do; answers cite the lease clause, quote, letter or record they come from, and nothing is decided, sent or shared until a person says so.
Why is the gear short at return?
Its overhaul falls due Aug 18, 2027, three months after return. Today it has 10 months left; on May 17, 2027 it will have 3, against the 60 the lease asks. No overhaul fits before return without 6 more hangar days, so the cost agent priced both paths.
Reprice it with escalation on January 1
Repriced: 57 × $21,642 = $1,233,594. The check agent recomputed alone: ¶3.4(c) escalates on each anniversary of the Delivery Date, so the compensation is $1,200,591. It disagrees by $33,003, and the decision is blocked until the figures agree.
What do we owe Aldermoor next?
Our position on the landing gear by Nov 13 (29 days), then the final records pack by Dec 15. Aldermoor owes us an answer on issues list revision 2 by Oct 21.
What if Arcadia never answers on the impeller?
Then the impeller's trace stays broken and Aldermoor can refuse it. The fallback is a new impeller, $84,000, ordered by Jan 15, 2027 to fit in the return check. The APU maker's records service has also been asked; its answer is due Oct 23.

Aircraft redelivery management runs a leased aircraft's return to the lessor — the lease return, or aircraft handback — from 24 months out to the signed technical acceptance certificate. In Aircraft Redelivery Management, seven agents quote every lease return condition, project the aircraft's state to the return date, price perform or compensate for each gap, check each other's numbers blind, chase back-to-birth records and draft every letter to the lessor. The lease technical manager asks them questions, decides and sends; the Head of Lease Management signs acceptance.
In the solution, a return project opens automatically 24 months before lease expiry — a setting — and the lease reader agent maps every return condition when the lease is added. IBA's 2023 redelivery survey says the key decisions are needed at least two years before return, so redelivery planning starts with the lease, not the return check.
The solution prices both paths and a person decides. The cost agent sets the lease's own compensation formula against real shop quotes, hangar days and holdover rent, and the check agent recomputes the formula blind — if the two differ, the decision is blocked. On the demo A330's landing gear, compensating costs $1,200,591 against $1,652,000 and 6 hangar days to overhaul; the lease technical manager chooses with a reason code and an e-signature.
Every finding from the lessor's records review and inspections goes on the list with a proposed response and the record or manual limit behind it — for example, a cargo door sill dent within SRM limits. A person approves, edits or rejects each response before anything is shared with the lessor.
Yes. The records agent keeps the return set in ATA Spec 2500 order, checks it against every records condition in the lease and chases each gap with shops, archives and prior holders, pricing a fallback part if a record cannot be found. It never edits a record or closes a gap; the records manager confirms each recovered document.
The redelivery agent re-plans every return each night against hangar slots, shop turn times and promises, and flags conflicts while there is time to act. In the demo it finds a hangar overlap four months ahead of one return check, and an engine shop visit that would come back 9 days after another ends — with a leased spare engine at $148,000 or a swap from spares as the ways to keep the return date. Holdover rent is read from each lease, so the cost of a slip is priced into every decision.
Yes. Agents never decide perform or compensate, accept a quote, send a letter, book a slot, edit a record, share with the lessor or sign. Letters over $1.5M or over budget need the Head of Lease Management, budget changes over $250,000 need the VP Fleet, and every action is on a chained audit trail.
