Engine shop records
PW1100G HPC rear hub inspection and replacement evidence
MROs, lessors, Aircraft records teams use the review to test whether delivered records support the stated position before GTF shop visit records reconciliation. The reviewer follows HPC rear hub AD status and Shop inspection record into Measured inspection result, Shop visit build record, logbook entries, tracking exports, and event records. The package delivered to the buyer is a discrepancy register, source index, owner-tagged request list, and closeout summary.
When this review is needed
- A maintenance, storage, conversion, or delivery event created new records that must be reconciled to status.
- The responsible team needs to know whether the gap is missing evidence, inconsistent data, or unresolved work.
- A prior owner, shop, or system migration may hold the only page that supports the claim.
The problem
Records packages for this topic usually mix source pages with summaries and correspondence. The defect appears when those materials disagree on applicability, accomplishment, or current configuration.
What gets reviewed
- Review shop inspection sheets for the affected rear hub location and recorded result.
- Check measurement evidence against the maintenance criteria supplied in the shop package.
- Trace replacement parts from certificate to final engine build.
- Compare shop visit release entries with the AD status update.
- Identify unsupported status lines before shop-visit closeout or engine transfer.
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 inspection result, measurement record, build sheet, and release entry align.
- Fail when a shop summary says inspected but the measurement sheet is absent.
- Pass when replacement trace connects certificate, installation, and engine release.
- Fail when AD status is closed before the shop findings are dispositioned.
Evidence normally required
- engine AD status report
- HPC rear hub inspection sheets
- shop visit teardown and build records
- measurement records
- replacement certificates
- engine logbook release entries
Common discrepancies
- Measurement sheet missing from the final shop package.
- Rear hub replacement shown in material records but not final build.
- Shop release date and status update date conflict.
- Inspection result recorded without engine or module serial reference.
What is at stake
A weak file can force repeated document requests and delay technical acceptance. It can also blur the difference between missing evidence and actual work that may still be due.

How the work runs
Frame 2023 Pw1100g
Confirm the exact event, affected file set, buyer role, and decision standard before any hpc rear hub ad status is treated as sufficient.
Trace Rear Hub
Walk the named evidence from index entry to source artifact and mark where the trail supports, conflicts with, or fails to answer the page-specific question.
Sort Review Gtf
Group exceptions by closure route: document retrieval, data correction, engineering disposition, authority response, or contractual decision.
Package Replacement Engine
Deliver the exception list, evidence map, and owner sequence in a form that can move directly into remediation, submittal cleanup, or transaction negotiation.
What the buyer receives
- Decision register for engine shop records exceptions
- Trace table from status claim to source evidence
- Correction and retrieval plan with owners assigned
- Management summary separating immediate blockers from monitor items
Who uses the output
- Engine records analyst uses the register to decide which lines can be accepted or escalated.
- Shop visit manager uses the evidence map to request missing technical records.
- Powerplant engineer uses the closure plan for transaction, audit, or delivery decisions.
How the work fits into the transaction or program
AD 2023-20-11 applies to certain PW1100G-JM engines after investigation revealed MRO shops were misinterpreting accepted knife edge coating wear limits on the HPC rear hub, and requires replacing the hub with a part eligible for installation; determine from shop records which limits revision the hub was inspected to at its last exposure, and whether the installed hub is an affected serial, evidence that sits in the shop's findings sheets rather than the operator's status list. The evidence set centers on engine AD status report, HPC rear hub inspection sheets, shop visit teardown and build records, and measurement records. The likely weak points are shop visit reports that do not state the wear limits applied, hubs accepted under the misread limits and returned to service, and status lists marking the AD not applicable based on engine age rather than hub history. Handoff: engine records analyst, GTF shop visit records reconciliation, PW1100G HPC rear hub inspection and replacement evidence.
Jurisdiction-specific considerations
FAA references are used as evidence context for recordkeeping and compliance support. The review does not treat one authority's record format as automatic acceptance by another authority or by a counterparty.
Regulatory limits
The review tests whether the delivered records support the stated position. It does not create regulatory approval, perform conformity, sign maintenance releases, or decide final acceptance for the responsible authority or certificate holder.
What this review does not cover
- Maintenance planning beyond the affected evidence lines
- Acceptance of parts or documents on behalf of a regulator
- Pricing advice for open technical exposure
Specific to this review
- For this review, wear-limit AD evidence depends on the recorded inspection result, not solely on shop visit completion.
- A recurring records trap is that the rear hub may be documented in module records that are separate from the engine cover package.
- A defensible closeout shows whether the hub passed inspection, was corrected, or was replaced.
- The scope uses the 2023 Pw1100g Hpc Rear question as the control point, so the review stays tied to GTF shop visit records reconciliation and the buyer decision behind it.
- The evidence starts with HPC rear hub AD status and follows Hub Evidence Review Gtf 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 Engine records analyst: 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 Inspection Replacement Engine Shop questions in the records or certification lane and sends technical acceptance issues to the authorized people who own them.
- The handoff value comes from Decision register for engine shop records exceptions; 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 HPC rear hub inspection and replacement evidence under AD 2023-20-11..

Frequently asked questions
What makes this records review different from a general file audit?
The scope is tied to 2023 pw1100g hpc rear and to the decision named in the request. A general audit can list weak records; this pass ranks the gaps by whether they block gtf shop visit records reconciliation or can be closed later without changing the decision.
What evidence has to be available before this work starts?
The starting point is hpc rear hub ad 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 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.
