787 engine records
Boeing 787 family engine shop-visit records review
This review checks the engine shop-visit package on a specific Boeing 787 family aircraft so the workscope, the parts fitted, and the release evidence hold together as one story. A records specialist runs it for the party trading or operating the tail, most often when an engine event drives the value or a redelivery is near. It reads the shop report, module build records, test-cell data, LLP disposition, and the release certificate, then confirms each part that went back on the engine traces to authorized-release paperwork. You receive an exception list against the shop visit, a source map from build sheet to release, and a closure plan for the trace breaks.
When this review is needed
- An engine drives most of the tail's value and the buyer wants the last shop visit fully traced.
- A module build shows parts fitted that the release certificate does not account for.
- LLP dispositions from the shop visit need to reconcile with the current LLP status list.
- A redelivery requires the engine package assembled and clean before the aircraft leaves.
The problem
An engine shop visit generates a thick package from several sources at once: the shop report, the module build sheets, test-cell runs, and a stack of release certificates for the parts that went back on. Those documents are produced by different hands on different days, and a single part fitted at module build without its authorized-release paper breaks the chain that a buyer or a receiving operator will test first. The value riding on the engine makes any unexplained gap expensive.
What gets reviewed
- The shop report and workscope reconciled against the reason the engine came off
- Module build records confirming which parts and LLPs went back into each module
- Authorized-release paperwork for every part fitted during the shop visit
- Test-cell data supporting the post-visit performance and the release decision
- LLP dispositions from the visit reconciled to the current LLP status list
- The engine release certificate tying the package to a return-to-service condition

What gets validated
- Each part fitted at module build has a release certificate matching its part and serial number
- LLP cycles at the visit reconcile between the build sheet and the status list
- The workscope in the shop report matches the parts and modules actually touched
- Test-cell results support the release condition the certificate claims
- The engine serial and configuration after the visit agree across the package and the airframe records
Evidence normally required
- The full engine shop-visit package for the visit under review
- Module build records and the associated parts lists
- Authorized-release certificates for parts fitted during the visit
- The current LLP status list for the engine
- Test-cell reports and the engine release certificate
Common discrepancies
- A part fitted at module build with no authorized-release certificate in the package
- LLP cycles that disagree between the build sheet and the current status list
- A workscope that references a module the build records do not show as opened
- A release certificate whose serial number does not match the part on the build sheet
What is at stake
A trace break at a module build can strand LLP life value, because a part without release evidence cannot carry its remaining cycles into a resale. An engine package that does not close undercuts the price of the whole aircraft, and reconstructing the shop trail after the visit is far harder than assembling it while the shop still holds the records.

How the work runs
Open the shop package
Assemble the shop report, module build sheets, test-cell data, and release certificates for the visit.
Trace parts to release
Match every part fitted at build to its authorized-release paperwork and part and serial numbers.
Reconcile the LLPs
Confirm LLP cycles at the visit agree between the build sheet and the current status list.
List the breaks
Record unsupported parts and LLP items and sequence the paperwork to recover.
What the buyer receives
- An exception list against the shop visit with each unsupported part or LLP item
- A source map running from the module build sheet through to the release certificate
- A closure plan for the release paperwork to recover and the LLP figures to reconcile
Who uses the output
- Asset managers pricing the engine and its LLP life from the documented condition
- Records teams assembling the engine package before a redelivery or a separate engine sale
- Continuing-airworthiness leads confirming the engine status the airframe records rely on
How the work fits into the transaction or program
The engine package is where a large share of a 787's traceable value concentrates, so this review clears it before the logbook and LLP reviews lean on the engine status. Its output feeds the redelivery binder or the data room, and its LLP reconciliation flows into the separate LLP traceability work when the engine is traded on its own.
Aircraft-specific considerations
787 engines run high-cycle, long-range operations, so a single shop visit can carry heavy LLP replacement and module work that multiplies the release paperwork to verify. Because so much of the tail's value sits in the engine, the shop package gets graded to a higher trace standard than most airframe records on the same aircraft. The review is scoped to the actual visits this engine has seen rather than a generic shop-visit template.
Jurisdiction-specific considerations
A part released on an FAA Form 8130-3 and one released on an EASA Form 1 both need to be present and valid for the register the tail serves, so the review flags where a release form has to be matched to the receiving system.
Regulatory limits
The review confirms the shop-visit records and release evidence trace and reconcile. It does not certify the engine, set LLP life on an authority's behalf, or make an airworthiness determination on the engine or the aircraft.
What this review does not cover
- Physical inspection, borescope, or performance assessment of the engine
- Re-certification or re-life of any engine part or LLP
- Any airworthiness determination on the engine or the aircraft
Specific to this review
- A module build is the most common place an engine trace breaks, because a single unpapered part fitted deep in a module can strand the LLP life around it.
- LLP value only transfers with release evidence, so a cycle figure that reconciles to the status list but not to a certificate does not hold at resale.
- The window to recover a shop record narrows once the shop closes the visit, so a redelivery timeline drives how much trace can still be assembled.

Frequently asked questions
Why does a single missing release certificate matter so much on an engine?
A part fitted during a shop visit carries life and value only when its authorized-release paperwork is on file. Without it, a downstream buyer cannot rely on the part's status, which can strand the LLP life stacked around it and pull down the price of the engine and the aircraft.
