Registry change
Equipment list and configuration review for a registry change
A registry-change equipment list review confirms that the aircraft equipment list matches what is installed and that each installation carries the release and approval evidence the receiving register will expect. It is run for the team preparing the transition, before handover, across the installed equipment, the release certificates behind it, and the modification approvals that put non-standard items on the aircraft. The work reconciles the equipment list to the installation and release records and flags items whose approval will not carry to the new register. You receive an equipment status view keyed to the aircraft equipment list, a gap list flagging unsupported installations, and a request set for the missing release evidence.
When this review is needed
- An aircraft is changing register and the receiving authority will reconcile the equipment list to what is installed.
- Equipment has been swapped, added, or removed across operators without the list being kept current.
- Non-standard installations rest on modification approvals the new register may not recognize.
- A handover date is set and the team needs to know which installed items lack release evidence.
The problem
An equipment list drifts every time a unit is swapped, and the drift is invisible until someone reconciles the list against the installation records. A part shown installed may have no release certificate on file, or an item on the aircraft may not appear on the list at all, and each mismatch becomes a question the receiving register raises during acceptance. The team preparing the transition inherits a list that reads complete and has to prove, line by line, that it reflects the aircraft.
What gets reviewed
- The aircraft equipment list reconciled against the installation and removal records
- Release certificates located for the installed equipment shown on the list
- Modification approvals confirmed for non-standard or added installations
- Items present on the aircraft but absent from the list identified and traced
- Equipment approvals tested for recognition on the receiving register
- Configuration effect of the equipment changes reconciled to the type design
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 item on the equipment list matches an installation record and a release certificate
- Non-standard installations carry a modification approval the receiving register recognizes
- No installed item appears on the aircraft without a corresponding line on the list
- Serial and part numbers on the list agree with the installation records for each position
- Equipment whose approval will not carry to the new register is identified with the reason
Evidence normally required
- The current aircraft equipment list
- Installation and removal records for the installed equipment
- Release certificates for the equipment shown installed
- Modification approvals for non-standard or added items
- Configuration and type design reference for reconciling the installations
Common discrepancies
- An equipment-list line with no release certificate retrievable for the installed unit
- A non-standard installation resting on an approval the new register does not recognize
- An item installed on the aircraft that never made it onto the equipment list
- A serial or part number on the list that disagrees with the installation record
What is at stake
An installed item without release evidence can hold the equipment configuration off the new register until the certificate is recovered or the item is replaced. An equipment list that does not reconcile to the installation records undermines the configuration baseline the rest of the transition rests on, so the mismatch has to be closed before the register change can settle.
How the work runs
Reconcile the list
Match every equipment-list line to an installation record and the unit actually fitted.
Trace the release evidence
Locate the release certificate behind each installed item shown on the list.
Check the approvals
Confirm non-standard installations carry an approval the receiving register recognizes.
Close the mismatches
Flag list-to-aircraft gaps and request the release and approval evidence needed.
What the buyer receives
- An equipment status view mapping each list line to its installation and release evidence
- A gap list flagging unsupported installations and list-to-aircraft mismatches
- A document request set for the release certificates and approvals still to be recovered
Who uses the output
- Continuing-airworthiness leads confirming the equipment configuration for the receiving register
- Asset managers tracking which installations could hold the configuration off the new register
- Records teams gathering the release evidence behind each installed item
How the work fits into the transaction or program
The equipment list review closes the configuration side of the registry-change package, working with the modification and repair strands to fix what is installed and approved. Its gap list feeds the export documentation, where the reconciled equipment configuration becomes part of the status the importing authority reviews.
Start with a single asset
Confirm the status list matches the underlying evidence.
Jurisdiction-specific considerations
FAA, EASA, and TCCA recognize equipment approvals and release forms differently, so an installation acceptable under the outgoing register can need a recognized approval for the new one. The review flags equipment whose approval basis will not carry and the release evidence the receiving register will expect.
Regulatory limits
The review reconciles the equipment list and traces the release and approval evidence. It does not approve an installation, issue a release certificate, remove or refit equipment, or determine that the aircraft configuration is airworthy.
What this review does not cover
- Physical inventory or inspection of the installed equipment
- Installing, removing, or re-approving any equipment
- Any airworthiness determination on the installed configuration
Specific to this review
- The equipment list drifts at every unit swap, so it is reconciled against installation records rather than trusted as maintained.
- An item can be physically installed and entirely absent from the list, which is harder to catch than a list line with no part behind it.
- Non-standard installations are where equipment approvals fail to carry, because the modification basis is register-specific in a way a standard fit is not.

Frequently asked questions
Why reconcile the equipment list if it has been kept current?
An equipment list drifts every time a unit is swapped, and the drift is only visible when the list is checked against the installation and release records. The review reconciles line by line so items with no release evidence, or items on the aircraft that never reached the list, are found before the receiving register raises them.
