Boeing 787 aircraft records review
A Boeing 787 records review tests one airframe and its engines against the documentation a deal or redelivery turns on, carried out for a lessor, buyer, or operator. Because this generation is managed largely as digital records and built around composite structure and an electrical architecture, the focus is repair substantiation against the approved composite repair data, the electrical and battery-related directive line, and whether the maintenance-system export holds up against the documents it was drawn from. You receive a per-area trace, a list of unsettled items, and the evidence each one needs.
When this review is needed
- A 787 is changing operators and the buyer wants its composite repair history substantiated.
- An electrical or battery directive applies to the serial number and the closure evidence needs confirming.
- Records live in a maintenance-information system and the exported position needs tying back to source.
- A redelivery offer is in play and the technical team wants an outside read on this electrical airframe.
The problem
The 787 is run as digital records, and its composite primary structure changes what a repair entry must prove: a bonded or laminated repair is judged against the approved repair data, not against metallic practice. A status export looks orderly, but the electrical and battery directive line on this type is dense, and when an export is accepted as the record without checking the documents underneath, repairs and directive closures can appear settled while the substantiation behind them is thin.
What gets reviewed
- Composite repair history checked against the approved repair data for each affected area
- Electrical, battery, and systems Airworthiness Directive position with accomplishment evidence
- Engine life-limited part trace by part and serial number across shop visits
- Maintenance-system export reconciled line by line to the source documents
- Modification and effectivity status confirmed for this serial number
- Time and cycle accumulation checked for internal consistency across the digital file

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 composite repair references approved repair data suited to the structure and zone it touches
- Every electrical and battery-related directive shows accomplishment evidence with the method recorded
- The maintenance-system export agrees with the underlying source documents rather than standing alone
- Engine life-limited part status ties to release paperwork and a consistent cycle history
- Recorded modifications are confirmed against the embodiment evidence for this serial number
- Accumulated hours and cycles reconcile across the exported records and the source entries
Evidence normally required
- Maintenance-information system export for the airframe
- Composite repair records with the supporting approved repair data
- Current AD and service bulletin status with accomplishment evidence
- Engine shop-visit reports carrying the life-limited part status
- Modification and embodiment records for the serial number
Common discrepancies
- A composite repair entered without the approved repair data behind it
- An electrical directive shown closed in the export but missing source accomplishment evidence
- Exported status that diverges from the documents it was generated from
- An engine life-limited part trace that lapses at a prior shop visit
- A modification recorded against the type but not evidenced for this airframe
What is at stake
A composite repair without its approved data may have to be re-engineered or re-substantiated before the next operator accepts the structure, which is slow and costly. An electrical directive that reads as closed in the export but lacks source evidence can resurface during transition, and gaps in a digital file are harder to reconstruct once the originating system is no longer accessible.
How the work runs
Anchor the digital baseline
Take the maintenance-system export as a starting position and identify the source documents that should support each entry.
Read the composite file
Check each repair against the approved repair data for the structure and zone it affects, flagging any without substantiation.
Work the electrical directives
Confirm accomplishment evidence and method for each electrical and battery-related directive on the serial number.
Reconcile and register
Record where the export and source diverge, and list each gap with the evidence needed to close it.
What the buyer receives
- A per-area trace across composite repairs, directive position, and engine life limits
- A findings register tying each item to its source and the gap that has to close
- A reconciliation note wherever the digital export and the source records disagree
Who uses the output
- Acquisition and asset teams pricing the airframe and engines
- Records teams preparing the transition or data-room package
- Engineering deciding how to treat a composite repair with thin substantiation
How the work fits into the transaction or program
The review sits between the digital export and acceptance, turning a system position into a source-supported trace before the airframe transfers. Its output anchors the transition package and the records baseline the receiving operator carries forward.
Start with a single asset
Start with a single tail and expand once the workflow is proven.
Aircraft-specific considerations
Composite structure on the 787 means a repair record proves itself against the approved repair data for the affected laminate or bonded zone, so the review reads each repair against that basis rather than metallic repair custom. The electrical architecture concentrates directive activity in the power and battery systems, so closures there are checked one directive at a time against original evidence.
Regulatory limits
The review confirms records completeness, consistency, and traceability. It does not make an airworthiness determination, re-substantiate a repair on an authority's behalf, or guarantee that a counterparty or authority will accept the aircraft.
What this review does not cover
- Physical inspection or non-destructive testing of composite structure
- Re-engineering or re-substantiation of a repair
- Any airworthiness determination or regulatory approval
Specific to this review
- A repair on this airframe is judged against the approved composite repair data for the affected zone, not against metallic repair practice.
- The 787 is managed largely as digital records, so the review reconciles the system export to source rather than treating the export as the record.
- The electrical and battery directive line on this generation is dense, so closures are evidenced one directive at a time.

Frequently asked questions
Can you work from the operator's maintenance-system export?
Yes. The export is the starting point and the review reconciles it to the underlying source documents, because an export can present a position the source evidence does not fully support.
Why are composite repairs handled differently?
A composite repair has to be substantiated against the approved repair data for the affected zone, so the review reads each one against that basis rather than against metallic repair conventions.
