AD evidence
AD 2025-04-14 Trent 1000/7000 IPC Front Air Seal records evidence
For lessors, airlines, and aircraft records teams, the trigger is a Trent shop visit or engine transfer. AD 2025-04-14 applies to Trent 1000 -x3 variants and Trent 7000-72/-72C engines and requires inspection of the IPC shaft assembly for cracking, with repetitive inspection or front air seal or shaft assembly replacement when findings require it. EE checks the AD status line, referenced EASA method, shop work cards, findings, replacement trace, engine serial tie, and configuration records, then returns an evidence map and closure request list for transfer or shop-visit review.
What gets reviewed
- AD 2025-04-14 (Amendment 39-22947, effective April 1, 2025) applies to Trent 1000 -x3 variants and Trent 7000-72/-72C engines and requires inspection of the intermediate pressure compressor shaft assembly for cracking and, on findings, repetitive inspections or replacement of the IPC shaft assembly front air seals, incorporating an EASA AD by reference, to prevent an IPC stage 1 disk burst.
- The review notes that decision: confirm the inspection was performed to the referenced EASA AD method, that findings drive the correct repetitive or replacement path, and that a replaced front air seal or shaft assembly carries its own trace.
- Tie every accepted line to the affected serial number, date, revision, or work package.
- Separate recoverable filing defects from issues that need technical disposition.

What gets validated
- Accept the ad 2025-04-14 trent 1000/7000 ipc front air seal position when source evidence matches the summary claim and affected asset.
- Question the ad 2025-04-14 trent 1000/7000 ipc front air seal position when a spreadsheet, index, or status flag is the only support.
- Escalate the ad 2025-04-14 trent 1000/7000 ipc front air seal item when configuration, serial, approval, or repeat-task logic changes the outcome.
Evidence normally required
- current AD or SB status report
- source accomplishment entry
- applicability and configuration evidence
- inspection or repair report
- utilization snapshot at compliance
Common discrepancies
- an engine file citing the FAA AD while the actual method lives in the referenced EASA AD that is not on file, a crack finding without the follow-on repetitive schedule, and a shaft-assembly swap logged without carrying inspection status forward.
- A ad 2025-04-14 trent 1000/7000 ipc front air seal summary cites evidence that is missing, stale, or filed under another asset.
- The closure package omits the document that would let the next reviewer repeat the conclusion.

How the work runs
Trent IPC source inventory
The review starts by listing the source records that actually name the IPC shaft assembly and front air seal claim, with file location, revision date, and owner recorded before any status conclusion is made.
Engine model applicability test
The next pass ties the AD applicability statement to serial, effectivity, configuration, and utilization data so the open item is not closed from a generic status line.
Finding path exception split
The findings separate missing source evidence, conflicting entries, stale revision references, and unsupported dispositions because each class needs a different closure route.
Transfer evidence handoff
The output names the exact record request, the accountable owner, and the decision that remains open for records, engineering, leasing, or maintenance control.
What the buyer receives
- AD 2025-04-14 Trent 1000/7000 IPC Front Air Seal evidence map with source-page references
- AD 2025-04-14 Trent 1000/7000 IPC Front Air Seal discrepancy register sorted by blocker, reservation, and monitor item
- AD 2025-04-14 Trent 1000/7000 IPC Front Air Seal document request list naming the exact missing or corrected record
- The review notes that decision note for the trent shop visit or engine transfer team
How the work fits into the transaction or program
AD 2025-04-14 (Amendment 39-22947, effective April 1, 2025) applies to Rolls-Royce Trent 1000 -x3 variants and Trent 7000-72/-72C engines and requires inspection of the intermediate pressure compressor shaft assembly for cracking and, on findings, repetitive inspections or replacement of the IPC shaft assembly front air seals, incorporating an EASA AD by reference, to prevent an IPC stage 1 disk burst; confirm the inspection was performed to the referenced EASA AD method, that findings drive the correct. The evidence set centers on current AD or SB status report, source accomplishment entry, applicability and configuration evidence, and inspection or repair report. The likely weak points are an engine file citing the FAA AD while the actual method lives in the referenced EASA AD that is not on file, a crack finding without the follow-on repetitive schedule, and a shaft-assembly swap logged without carrying inspection status forward. Handoff: engine records analyst, trent shop visit or engine transfer, AD 2025-04-14 Trent 1000/7000 IPC Front Air Seal records evidence.
Regulatory limits
This ad 2025-04-14 trent 1000/7000 ipc front air seal records review does not approve data, issue a release, determine airworthiness, or guarantee authority acceptance. Regulators, authorized persons, operators, and transaction parties make final decisions under their procedures.
Specific to this review
- The Trent review starts with engine model applicability because Trent 1000 -x3 and Trent 7000-72/-72C records may sit in different delivery, lease, and shop-visit files.
- The inspection evidence must identify the IPC shaft assembly, the method incorporated by reference, and the finding that drives repeat inspection or replacement.
- The front air seal trace is reviewed as its own installable part trail, so a replacement claim needs release paperwork, installation date, and engine serial tie.
- The failure concern is IPC stage 1 disk burst prevention, so an open crack finding is not treated as an ordinary deferred paperwork item.
- For transferred engines, the file has to reconcile shop worksheets, AD status sheet, parts release certificates, and configuration snapshots for the same serial.
- The review flags cases where the AD line says complete but the underlying work card only shows access, preparation, or a planned later inspection.
- The repeat interval is checked from the finding date and relevant utilization so the next due point does not drift after a shop visit or lease transition.
- The output gives the powerplant team exact requests for MRO records, parts trace, EASA-method evidence, and owner-held engine files before signoff.

Frequently asked questions
What makes this records review different from a general file audit?
The scope is tied to 2025 trent 1000 7000 and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block trent shop visit or engine transfer or can be closed later without changing the decision.
What evidence has to be available before this work starts?
The starting point is ad status line, the current status source, and any index or matrix that tells reviewers where the supporting artifact should live. Missing inputs are logged as findings rather than filled with assumptions.
Who decides whether an open item is acceptable?
The review explains what the evidence supports and gives engine records analyst a closure path. Acceptance remains with the buyer, operator, authority, delegated engineer, or authorized person responsible for the underlying airworthiness or certification decision.
