LEAP structural repairs
Structural-repair records review for LEAP engine assets
This review confirms that the structural repairs recorded on a LEAP-powered aircraft each rest on approved data and appear correctly on the structural repair map. It is run for a lessor, airline, or manager evaluating, transferring, or maintaining the asset, usually where damage and repairs have accumulated across the airframe's service. It works through the repair maps, damage reports, structural repair manual references, and approval data, tying each repair to its basis and location. You receive a supported exception list, a source map per repair, and a closure plan for this asset.
When this review is needed
- Structural repairs have accumulated on a LEAP-powered aircraft and each has to be tied to approved data and its location.
- A buyer wants the structural repair map reconciled to its damage reports and approvals before pricing the asset.
- A repair references a manual section but the approval basis or the damage report behind it is missing.
- A repair near a life-limited structural area needs its basis and any AD interaction confirmed.
The problem
Structural repairs carry more scrutiny than most because they touch primary structure and interact with fatigue and damage-tolerance limits. On a LEAP-powered aircraft, each repair should appear on the structural repair map, name the damage report that prompted it, and reference the manual section or approved data that authorized it. When a repair on the map has no damage report, or references a manual section without the approval that made it applicable, the structural record cannot support the repair at the level a buyer or an auditor expects.
What gets reviewed
- Each structural repair placed on the repair map with its location and extent
- Damage reports tied to the repairs they prompted
- Structural repair manual references and approved data confirmed for each repair
- Repairs near fatigue-critical or damage-tolerance areas checked for any inspection burden they carry
- Approval data confirmed applicable to the repair and the structure
- The repair map reconciled to the damage reports and approvals it summarizes

What gets validated
- Every repair on the map ties to a damage report and an approved-data reference
- Manual references cited on a repair apply to the structure and the damage
- Repairs in fatigue-critical areas carry any recurring-inspection requirement forward
- Approval data is present and applicable to each structural repair
- The repair map reconciles to the underlying damage reports and approvals
Evidence normally required
- The structural repair map for the aircraft
- Damage reports behind the recorded repairs
- Structural repair manual references and approved data
- Any recurring-inspection requirements tied to a repair
- Effectivity and configuration data relevant to the repairs
Common discrepancies
- A repair on the map with no damage report to explain what it addressed
- A manual reference cited on a repair without the approval that made it applicable
- A repair in a fatigue-critical area whose recurring inspection was not carried forward
- A structural repair whose approved data does not match the structure it was applied to
What is at stake
A structural repair without traceable approval data can force re-substantiation or removal, and near a fatigue-critical area it can trigger repeat inspections the records must then carry forward. An unmapped or undocumented repair puts the whole structural history in question at a transaction, and reconstructing a damage report and its approval years later is among the hardest records recoveries.

How the work runs
Map the repairs
Place each structural repair on the map with its location and extent.
Tie repairs to damage and data
Match each repair to its damage report and confirm the approved data behind it.
Check the inspection burden
Confirm repairs in fatigue-critical areas carry any recurring inspection forward.
List the exceptions
Flag repairs without a damage report or approval and the evidence needed to close them.
What the buyer receives
- A supported exception list of structural repairs that do not trace to approval or a damage report
- A source map linking each repair to its damage report, manual reference, and approval
- A closure plan for recovering the evidence each open structural repair needs
Who uses the output
- Asset managers pricing the exposure that unsupported structural repairs carry
- Records teams recovering damage reports and approvals behind mapped repairs
- Engineering assessing a structural repair whose basis or inspection burden is unclear
How the work fits into the transaction or program
The structural-repair review connects to the AD and continued-airworthiness records, because a structural repair can carry its own inspection requirement forward. It runs before the structural history feeds a transaction, so the repair map a counterparty reads is one where every repair traces to a damage report and an approval.
Aircraft-specific considerations
On a LEAP-powered aircraft the structural repairs sit on the airframe rather than the engine, so the review reads them against the airframe's structural repair manual and damage-tolerance basis rather than an engine document. Because the airframe is relatively young, the repair map is usually short, which makes a single undocumented or unmapped repair a larger share of the structural record and correspondingly more visible at a transaction.
Regulatory limits
The review confirms each structural repair is internally consistent, mapped, and supported by approved data. It does not approve a structural repair, develop repair or damage-tolerance data, perform an inspection, or make an airworthiness determination on the structure.
What this review does not cover
- Performing or inspecting any structural repair
- Developing or approving structural repair or damage-tolerance data
- Any airworthiness determination on the structure
Specific to this review
- On a LEAP-powered airframe a mapped repair with no damage report is the most common structural finding, because the repair was recorded but the reason for it was filed elsewhere.
- Repairs in fatigue-critical areas often carry a recurring inspection that the structural record must track forward, and a dropped inspection is a hidden exposure the map alone does not show.
- A short repair map on a young airframe raises the visibility of any single undocumented repair, so gaps that would blend into a legacy record stand out here.

Frequently asked questions
A structural repair is on the map and looks sound. Why chase the damage report and approval?
A structural repair is only supported if it names the damage it addressed and the approved data that authorized it. Without the damage report and approval, a buyer or auditor cannot confirm the repair was appropriate to the structure, and near a fatigue-critical area a missing recurring inspection can compound the exposure well beyond the single repair.
