Airworthiness review file
Boeing 737NG airworthiness review evidence records review
This review examines the airworthiness review file that a Boeing 737NG carries, confirming that each review certificate rests on evidence a records team can retrieve. A senior records specialist runs it when a 737NG is being valued, transferred, or brought under a new continuing-airworthiness organization. It looks at the review certificate history, the CAMO recommendation trail behind it, open-finding logs, and the continued-airworthiness status the certificate was issued against. You receive a supported exception list, a map from each certificate to its source, and a closure plan scoped to this specific tail.
When this review is needed
- A 737NG is entering diligence and a buyer will test whether each review certificate is actually supported.
- The tail is moving to a new CAMO that must issue the next recommendation on a clean prior file.
- An open finding from a previous review was never cleared and now blocks the current certificate.
- A registry change means the airworthiness review basis has to be reconstructed for a different authority.
The problem
An airworthiness review certificate is only as strong as the recommendation and status list behind it, and on a 737NG that has passed through several operators those supporting layers scatter. The certificate reads clean on its face while the finding it was conditioned on sits open two reviews back, or the status list the recommendation relied on no longer matches the current AD and life position. A records team inherits the certificate but not the reasoning that produced it.
What gets reviewed
- Review certificate history for the tail, each certificate tied to the recommendation that produced it
- CAMO recommendation evidence and the status the recommendation was issued against
- Open-finding logs from prior reviews checked for items carried rather than cleared
- Continued-airworthiness status reports current as of each review date
- AD and life-limited position reconciled to the certificate's stated basis
- Conditions and limitations attached to any certificate and their disposition
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 review certificate traces to a recommendation supported by a status list from the same period
- Findings raised at a prior review are shown closed or explicitly carried, not silently dropped
- The AD and LLP position behind the recommendation matches the status the file actually holds
- Any condition attached to a certificate has a documented disposition before the next review
- Certificate dates and validity align with the maintenance events recorded around them
Evidence normally required
- The airworthiness review file with the full certificate history for the tail
- CAMO recommendation reports and the status lists they were based on
- Open-finding registers from prior review cycles
- Current AD status and life-limited part status reports
- Any authority correspondence tied to a prior review or condition
Common discrepancies
- A certificate whose recommendation cannot be matched to a status list from the same date
- A prior-review finding carried forward across cycles without a closure record
- A condition attached to an earlier certificate that was never dispositioned
- A recommendation issued against an AD position the current file no longer supports
What is at stake
If the file behind the certificate cannot be reconstructed, the next review organization will not adopt it and issues its own recommendation from scratch, which stretches the timeline and can surface findings that were carried silently. A buyer who cannot trace the certificate to evidence discounts the asset or holds the deal open until the gap closes.

How the work runs
Assemble the certificate chain
Lay out every review certificate for the tail with its date, validity, and issuing organization.
Tie each certificate to its basis
Match each certificate to the recommendation and the status list that supported it.
Chase the open findings
Trace findings across cycles to confirm they were closed or are explicitly carried.
Report exceptions and closure
Deliver the exception list, source map, and a plan for the findings that block the current certificate.
What the buyer receives
- A supported exception list keyed to each review certificate in the history
- A source map linking every certificate to its recommendation and status evidence
- A closure plan sequencing the open findings that block the current certificate
Who uses the output
- Asset managers deciding whether the review certificate history holds under diligence
- CAMO leads preparing to issue the next recommendation on this tail
- Records teams reconstructing the review basis for a registry or organization change
How the work fits into the transaction or program
The airworthiness review file sits above the day-to-day status records and depends on all of them being current at each review date. This review reconstructs that dependency so the certificate history can be relied on, and it feeds the recommendation the next review organization will build on or the diligence pack a buyer works from.
Aircraft-specific considerations
A 737NG in the used fleet has typically seen several review cycles under different organizations, so the certificate history rarely reads as one continuous chain. Engine and APU changes, cabin and avionics STC embodiment, and structural repair activity all feed the status a recommendation was issued against, and any of them can be the layer that no longer reconciles to the certificate on file.
Jurisdiction-specific considerations
The airworthiness review construct is an EASA continuing-airworthiness feature, so a 737NG moving between an FAA and an EASA basis needs the review evidence rebuilt in the terms the receiving authority recognizes rather than carried across as issued.
Regulatory limits
This review reconstructs and checks the evidence behind the certificate history. It does not issue or renew an airworthiness review certificate, make an airworthiness determination, or grant any approval, all of which rest with the review organization and the authority.
What this review does not cover
- Issuing or renewing any airworthiness review certificate
- Physical survey or inspection of the aircraft
- Any airworthiness determination on the tail
Specific to this review
- A review certificate can read clean while the finding it was conditioned on sits open in a log two cycles earlier.
- The recommendation, not the certificate, is where the reasoning lives, so a lost recommendation breaks the trace even when the certificate survives.
- A recommendation issued against a since-superseded status list is the most common reason a certificate no longer reconciles to the current file.

Frequently asked questions
Can you reissue the airworthiness review certificate for us?
No. That authority sits with a qualified review organization. This work rebuilds and verifies the evidence behind the existing certificate history so the organization that does issue the next one starts from a file it can rely on.
