Single-aisle assets
Narrowbody aircraft records review
A narrowbody records review is for lessors, airlines, and acquisition teams preparing a single-aisle aircraft for a lease return, sale, or transition. The trigger is usually an offered return or a deal under diligence on a high-utilization airframe. We review AD accomplishment evidence, cycle-driven life limits, heavy-check work packages, and component release certificates against the underlying source documents. You receive a discrepancy register, a reconciled status view that ties tracking output back to source records, and the evidence each open item needs to close.
When this review is needed
- A single-aisle aircraft with heavy daily utilization is offered for return and the records carry a large flight-cycle count.
- A buyer wants an independent read of a narrowbody's status before pricing the asset.
- A heavy-check interval is approaching and the operator wants the records baseline confirmed before induction.
- A move between operators is planned and the records have to support the next lease.
The problem
Single-aisle airframes turn short sectors and build cycles fast, so the record set fills with repetitive task accomplishment and frequent rotable swaps. Status lists come straight out of a tracking system, while the source documents behind high-cycle items are rarely read in full when a return is offered. A discrepancy that only surfaces after acceptance lands on the next holder as cost.
What gets reviewed
- AD accomplishment evidence on a high-cycle airframe, including recurring-inspection intervals
- Service Bulletin and modification status with effectivity resolved by serial number
- Cycle-driven life-limited part status with continuous time and cycle traceability
- Heavy-check and structural-inspection work packages and their non-routine findings
- Authorized release certificates for components installed across successive shop visits
- Tracking-system output reconciled against the documents that justify it
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
- Each AD shows accomplishment with the method of compliance and the recurring-inspection status where one applies
- Cycle-driven life limits trace to release documentation with a consistent cycle history
- Heavy-check non-routines reconcile with the issued task cards and their sign-off
- Each component release uses a release document appropriate to the installation and the registry
- Time-since-new and cycles-since-new agree across logbooks and the status list
- Recurring-inspection due times reflect the actual cycle accumulation rather than a calendar estimate
Evidence normally required
- Current AD and SB status reports for the airframe and engines
- Life-limited part status list with cycle accumulation by part
- Heavy-check work packages and the associated non-routine cards
- Airframe and engine logbooks or their digital equivalents
- Component release certificates covering the lease or ownership period
Common discrepancies
- An unsupported recurring AD where the evidence for an interim accomplishment is missing
- Cycle counts that disagree between the status list and a shop report
- Release certificates absent for rotables fitted during a heavy check
- Non-routine repairs recorded without the substantiation that sits behind them
- Status-list life remaining that the underlying documents do not support
What is at stake
Accepting a narrowbody with broken cycle traceability or an unsupported recurring AD moves that exposure to whoever holds the asset next. The aircraft may need remediation before it can re-lease, and recovering the gap is harder once the prior operator has been released from the deal.
How the work runs
Frame the cycle baseline
Establish the airframe's cycle and hour position and identify the cycle-driven limits and recurring ADs that govern this aircraft.
Reconcile status to source
Compare AD, life-limit, and rotable status against accomplishment and release evidence in the source documents.
Register discrepancies
Record each finding with its source document, evidence trace, and effect on cycle traceability.
Map closure
Recommend a closure path and responsible party so the return or sale can proceed or be driven to resolution.
What the buyer receives
- A discrepancy register pairing each finding with its source document and evidence trace
- A reconciled status view that ties tracking output back to the source records
- A closure recommendation for each item with the responsible party named
- A short read on the items most likely to affect re-lease or sale value
Who uses the output
- Asset managers deciding whether to accept the return or adjust the price
- Records teams closing gaps before the airframe re-leases
- Transaction stakeholders pricing the residual records risk
How the work fits into the transaction or program
The review runs ahead of technical acceptance so cycle-driven findings can be priced or driven to closure while the outgoing operator still carries the obligation. It feeds the redelivery binder and the records baseline that the next operator inducts against.

Start with a single tail and expand once the workflow is proven.
Aircraft-specific considerations
Short-sector single-aisle operation pushes cycle limits ahead of calendar limits, so the decisive records on a narrowbody are usually recurring AD intervals and life-limited part cycle counts. High rotable turnover makes release certificates the most frequent gap type on this class of asset.
Jurisdiction-specific considerations
Where a single-aisle aircraft moves between authorities, a component released on one authority's form is not automatically acceptable under the receiving one, and the recurring-inspection program has to line up with the next operator's approved basis.
Regulatory limits
This review establishes records completeness, consistency, and traceability. It does not make an airworthiness determination, stand in for the operator or the authority, or guarantee that a return or sale will be accepted.
What this review does not cover
- Physical inspection or borescope of the airframe and engines
- Negotiation of the commercial return or sale terms
- Issuance of any approval or airworthiness determination
Specific to this review
- Short-sector narrowbody operation accumulates flight cycles quickly, so cycle-driven limits and recurring AD inspections are usually the decisive records rather than calendar items.
- High rotable turnover means release certificates are the most frequent gap type found on a single-aisle return.
- A recurring AD requires evidence of each accomplishment in the interval, so the review checks the interim history rather than only the most recent entry.

Frequently asked questions
Why do cycle counts matter so much on a narrowbody?
Short sectors accrue cycles faster than hours or calendar time, so cycle-driven life limits and recurring structural inspections reach their thresholds first. The review verifies cycle history is continuous and consistent across logbooks, shop reports, and status lists.
