When this review is needed

What gets reviewed
- Match module and disk LLP status to the current status line and affected serial or configuration.
- Check back-to-birth trace for high-value parts for date, revision, work scope, and closure support.
- Review shop visit workscopes and build standard against logbook entries, releases, and tracking exports.
- Confirm performance restoration and release records is present where the acceptance criteria require it.
- Assign each exception to a closure owner with the evidence needed.
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
- Pass when the source record shows the same serial, status, date, and configuration as the summary.
- Fail when hp disk carried on status sheet without trace to birth.
- Check repetitive or life-limited items for a clear last-done and next-due basis.
- Escalate when the release or approval document is absent from the supplied package.
Evidence normally required
- module and disk LLP status
- back-to-birth trace for high-value parts
- shop visit workscopes and build standard
- performance restoration and release records
Common discrepancies
- HP disk carried on status sheet without trace to birth.
- Green-time consumption unreconciled between airframes.

How the work fits into the transaction or program
Assess a GE90-94B/-115B on a Boeing 777 at lease return, trade, or part-out, verifying LLP status against the very high per-part values, module condition, and AD/SB embodiment, because widebody engine LLPs dominate the asset value and a single mistraced high-pressure spool part can move the deal. The evidence set centers on module and per-disk LLP status with back-to-birth trace, AD/SB embodiment for the HP spool and combustor, shop visit workscopes and build standard, EGT margin and performance-restoration history, and. The likely weak points are a high-value HP disk carried on the status sheet without back-to-birth substantiation, LLP consumption on a green-time -115B unreconciled between airframes, and a part-out harvest plan that undervalues LLPs because the trace gaps were not caught. Handoff: technical asset manager, 777 lease return, engine trade, or part-out, GE90 LLP and shop visit.

Aircraft-specific considerations
Boeing 777 family evidence is reviewed as a model-specific records set. Configuration, utilization history, transferred assemblies, and program status are kept separate from generic fleet assumptions.
Jurisdiction-specific considerations
FAA and EASA references are used as record expectations for the evidence set. The review does not assume automatic acceptance by another authority, operator, or contract party.
Regulatory limits
This records review does not approve data, release an aircraft or part to service, or make an airworthiness determination. Regulators, authorized persons, operators, and contract parties retain the final decision under their procedures.
What this review does not cover
- Physical inspection of the aircraft, engine, part, or article
- Commercial negotiation of price, reserves, warranty, or lease terms
- Regulatory submissions or approvals made on behalf of the applicant
Specific to this review
- The commercial exposure often sits in one high-value spool part rather than the whole engine file.
- Part-out review needs trace strength by harvest item, not solely engine acceptability.
- Module condition is read beside LLP trace because value depends on both remaining life and proven configuration.
- The scope uses the Ge90 Widebody Engine Records question as the control point, so the review stays tied to 777 lease return, engine trade, or part-out and the buyer decision behind it.
- The evidence starts with module and disk LLP status and follows Review Return Part Out references until every exception has a source location and a reason code.
- The finding logic separates missing paperwork, conflicting status, stale revision data, and unsupported disposition because each class closes through a different owner.
- The timing matters for Technical asset manager: the output is useful only if the unresolved items are visible before acceptance, submittal, handback, or negotiation pressure fixes the sequence.
- The boundary control keeps LLP Shop Visit Evidence questions in the records or certification lane and sends technical acceptance issues to the authorized people who own them.
- The handoff value comes from GE90 records discrepancy register with source-page references; it gives the next reviewer a precise map instead of another broad request for a better file.
- The source discipline is stricter on this page than on a general audit because the claim being tested is Verify GE90 LLP trace, module condition and AD status on a 777 against records before a return, trade or part-out..

Frequently asked questions
What makes this aircraft review different from a general file audit?
The scope is tied to ge90 widebody engine records and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block 777 lease return, engine trade, or part-out or can be closed later without changing the decision.
What evidence has to be available before this work starts?
The starting point is module and disk llp status, 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 technical asset manager a closure path. Acceptance remains with the buyer, operator, authority, delegated engineer, or authorized person responsible for the underlying airworthiness or certification decision.
