Structural repairs
Bombardier Global 7500 structural repair records review
A Global 7500 structural-repair records review confirms that each structural repair on a tail traces from its damage report to an approved basis and a charted location. It is run for a lessor, operator, or management provider verifying the structural repair history on a specific aircraft. It reads the structural repair map, the damage reports, the structural repair manual references, and the approval data behind each repair, then reconciles them against the airframe. You receive a supported exception list, a source map from damage to approval, and a closure plan for the aircraft under review.
When this review is needed
- A Global 7500 is being traded and its structural repair history has to be defensible before a buyer inspects it.
- A repair to composite structure was carried and its structural repair manual reference needs verifying.
- A ground-damage event was repaired and the damage report, disposition, and approval need reconciling.
- A management transition left the structural repair map and the approval files held by different parties.
The problem
Structural repairs draw the most scrutiny in diligence and carry the highest cost when their basis cannot be proven. A repair carried to structural repair manual limits still needs the reference and revision recorded, and a repair beyond those limits needs a separate approval that a routine sign-off does not provide. On a composite airframe the repair may be invisible on inspection yet still lack a valid basis, so the record is the only place its legitimacy is established. When the map, the damage reports, and the approvals sit in different places, no one holds the whole structural picture.
What gets reviewed
- Every structural repair plotted on the repair map against the airframe location it addresses
- Damage reports matched to the disposition and the repair actually carried
- Structural repair manual references confirmed for the correct limits and revision
- Repairs beyond structural repair manual limits checked for a separate approval
- Approval data confirmed appropriate to the repair, the structure, and the jurisdiction
- The repair map reconciled to the type design so no repair sits outside a known location

What gets validated
- Each structural repair traces from a damage report through disposition to a closing entry
- Structural repair manual repairs stay within the limits and cite the revision in effect
- Repairs beyond structural repair manual limits carry a separate approval appropriate to the structure
- Approval data matches the repair, the location, and the register the aircraft operates on
- No repair on the map lacks a source document a diligence reviewer would accept
Evidence normally required
- The structural repair map or dent-and-buckle chart for the serial number
- Damage reports and engineering dispositions for structural events
- Structural repair manual references cited for each repair
- Approval data for repairs beyond structural repair manual limits
- The type design and structural reference to place repairs against
Common discrepancies
- A composite structure repair logged with no structural repair manual reference or revision
- A repair beyond structural repair manual limits with no separate approval on file
- A damage report with a disposition but no closing entry recording the repair
- A structural repair on the airframe with no location charted on the repair map
What is at stake
A structural repair without a traceable approved basis can force re-substantiation or rework, which on primary structure is among the most expensive outcomes in a records file. A repair beyond structural repair manual limits with no separate approval is a serious finding that a buyer will not accept on trust. On composite structure the stakes are higher still, because an out-of-limit repair is not visible and the record is the only guard against it.

How the work runs
Chart the repairs
Plot every structural repair on the map against the airframe location it addresses.
Trace to the damage
Match each repair to its damage report and the disposition that authorized it.
Test the basis
Confirm structural repair manual references and revisions, and separate approvals for out-of-limit repairs.
List the exceptions
Rank repairs without a valid basis and set out what each one needs to close.
What the buyer receives
- A supported exception list ranking each structural repair by the strength of its basis
- A source map from each damage event to its repair, reference, and approval
- A closure plan naming the reference or approval each unsupported repair needs
Who uses the output
- Asset managers pricing the structural history a buyer's team will scrutinize closely
- Engineering deciding how to treat a repair recorded without an approval basis
- Records teams assembling a defensible structural repair map before diligence
How the work fits into the transaction or program
The structural-repair review is the highest-stakes slice of the repair picture, so it deepens the repair-approval work on the structure that matters most to a buyer. Its exception list drives remediation while the engineering that dispositioned each repair is still reachable, and the settled structural repair map becomes a focal point of the data room a transaction is built on.
Aircraft-specific considerations
The Global 7500 uses composite primary structure, so a repair can be sound and invisible on inspection while still resting on a reference that was never recorded, which makes the paperwork the primary evidence of its legitimacy. The structural repair manual for a new-generation airframe revises as service experience accumulates, so the revision cited on each repair matters. Because the fleet is largely managed, structural events repaired at stations away from the primary provider often generate paperwork that reaches the file separately, and the review pulls it back together.
Jurisdiction-specific considerations
A Global 7500 that has operated on both an FAA and an EASA register may carry structural repairs approved under one system that need a recognized basis on the other. The review notes where a repair's approval will need supplementing for the receiving register, without asserting that either authority accepts it as held.
Regulatory limits
The review confirms each structural repair is supported by an approved basis and a closing entry. It does not approve a repair, develop repair data, or make an airworthiness determination on the structure.
What this review does not cover
- Physical inspection or non-destructive testing of the structure
- Developing or approving structural repair data
- Any airworthiness determination on the structure or a repair
Specific to this review
- On composite structure the record is the primary evidence a repair is legitimate, because an out-of-limit repair may pass a visual inspection while still lacking a valid basis.
- The structural repair manual revision cited on a repair matters, since limits and methods evolve as service experience on a young type accumulates.
- A repair beyond structural repair manual limits needs a separate approval, and that approval is the single item most likely to be missing on a structural finding.

Frequently asked questions
Why does a structural repair on composite need the record even when it looks sound?
Because a repair to composite structure can pass a visual check while still resting on an out-of-limit method or an unrecorded reference. The physical repair does not reveal its own approval basis, so the record is the only place its legitimacy is established, which is why the paperwork carries so much weight on this structure.
