Operator certificate transfer
Equipment-list records for an operator AOC transfer
This review confirms whether the equipment list and configuration records for an aircraft will hold when it moves onto a new operator's certificate. It runs before handover, for the transferring party, so the aircraft equipment list agrees with the airframe before the receiving side inspects it. The work reconciles each listed item with its installation record, release certificate, and modification approval, and checks the list against what is actually installed. You get an equipment-list evidence map, a gap list where the list and the airframe diverge, and a document request set for the installation and approval records the receiving operator will ask for.
When this review is needed
- An aircraft is changing operator certificates and the receiving side will check the equipment list against the cabin and systems fitted.
- Cabin and avionics changes were made without the equipment list being kept current alongside them.
- An installed item has an installation record but no release certificate filed against it.
- The receiving operator's fit standard differs and any deviation on the list has to be explained.
The problem
An equipment list drifts out of step with the aircraft as items are added, swapped, and removed, and the paper often lags the wrench by months. At an operator transfer the receiving side does not take the list on trust; it walks the aircraft and matches what it finds to the list and the records behind each entry. Items on the list that are no longer fitted, and items fitted that never made the list, both surface at once, and each one needs an installation record and a release to settle it.
What gets reviewed
- Each equipment-list entry reconciled against the item actually installed
- Installation records confirmed for every item on the list and every item fitted
- Release certificates matched to the installed items by part and serial number
- Modification approvals confirmed for items added by a change to the aircraft
- Deviations from the receiving operator's fit standard identified and explained
- The equipment list ordered for the receiving side's walk-through and reconciliation

What gets validated
- Every item on the equipment list is actually installed on the aircraft
- Every installed item appears on the equipment list with an installation record
- Release certificates match the part and serial numbers of the fitted items
- Items added by modification carry the approval that permitted the installation
- The list reflects the configuration as of the transfer date, not an earlier fit
Evidence normally required
- The aircraft equipment list and configuration records
- Installation records for cabin, avionics, and systems items
- Release certificates for the installed equipment
- Modification approvals for items added by a change to the aircraft
- The receiving operator's fit standard, where one has been set
Common discrepancies
- An item on the equipment list that is no longer installed on the aircraft
- An installed item that never made it onto the equipment list
- A fitted item with an installation record but no release certificate on file
- An item added by modification with no approval recorded for the installation
What is at stake
A divergence between the list and the airframe unsettles the configuration the receiving operator is accepting, and an item it cannot tie to an installation record and a release stays in question. Left unresolved, that question can hold acceptance or force the item to be removed to restore a known state. Discovered during the transfer walk-through, these mismatches surface with no time left to gather the records that would have closed them.
How the work runs
Reconcile list to airframe
Match every equipment-list entry to what is installed and note items fitted that the list omits.
Confirm records for each item
Tie each item to its installation record, release certificate, and any modification approval.
Resolve the deviations
Explain differences from the receiving operator's fit standard and flag items needing a confirmed basis.
Deliver map, gaps, and requests
Hand over the equipment-list evidence map, the ranked gap list, and requests for the missing records.
What the buyer receives
- An equipment-list evidence map tying each entry to its installation and release records
- A gap list where the list and the airframe diverge, ranked by acceptance weight
- A document request set for the installation records and releases still needed
Who uses the output
- Asset managers gauging the exposure in a list that has drifted from the airframe
- Receiving-operator staff walking the aircraft against the list at acceptance
- Records leads reconciling the equipment list before the transfer walk-through
How the work fits into the transaction or program
This review comes before the receiving operator walks the aircraft against its records. It closes the divergences between the list and the airframe ahead of that walk-through, so the receiving side reconciles a list that already agrees with what is fitted rather than logging mismatches to chase after the fact.

Jurisdiction-specific considerations
Between FAA and EASA operators the fit standards and the release paper behind installed items can differ, and an item accepted under one regime may need its basis confirmed under the other. The review marks entries whose approval or release crosses the authority line, so a deviation from the receiving operator's standard is explained before it becomes an acceptance question.
Regulatory limits
The review reports what the equipment-list and configuration records support. It does not make an airworthiness determination, approve any installation, issue a release certificate, and does not replace the receiving operator's or authority's acceptance of the installed configuration.
What this review does not cover
- Physical inspection or functional check of installed equipment
- Approving any installation or modification
- Issuing release certificates for installed items
Specific to this review
- An equipment list drifts from the airframe because paper lags installation, so the receiving side's walk-through finds both phantom entries and unlisted fitted items at once.
- An item with an installation record but no release stays in question, since the record shows it was fitted but not that the part was approved for use.
- Items added by modification are a frequent miss on the list, because the change gets embodied while the equipment list is never updated to match.

Frequently asked questions
Our equipment list is maintained. Why walk it against the aircraft again at transfer?
A maintained list can still lag recent changes, and the receiving operator accepts the configuration it can see, not the one on paper. The review reconciles the list to the airframe and confirms the records behind each item, so the walk-through at acceptance finds agreement rather than a set of mismatches.
