Bombardier Global 7500 repair-approval records review
A Global 7500 repair-approval records review confirms that every repair and alteration carried on a specific tail is backed by approved data and a clean return-to-service entry. It is run for a lessor, operator, or management provider evaluating, trading, or continuing to hold the aircraft. It walks the damage report, the engineering disposition, the approval basis, and the sign-off for each item, then plots them on the airframe repair map. You receive a supported exception list, a source map tying each repair to its evidence, and a closure plan scoped to this serial number.
When this review is needed
- A Global 7500 is heading into diligence and its repair history has to be defensible before a buyer's team opens the file.
- A cabin or interior alteration was embodied and no one has confirmed the approval basis behind it.
- Damage from a ground event was repaired at a station away from the primary maintenance provider and the paperwork arrived separately.
- A management transition left the repair map partly assembled and the new provider needs it settled.
The problem
On a young business jet like the Global 7500, most repairs are minor and get logged quickly, which is exactly why the approval basis behind them is easy to skip. A dent repaired to structural repair manual limits still needs the reference recorded, and an interior change touching a cabin management system can cross into alteration territory that a routine sign-off does not cover. When those items are scattered across logbook entries and separate work packages, no one holds a single picture of which repairs are actually substantiated.
What gets reviewed
- Every repair and alteration in the logbooks and work packages plotted onto the airframe repair map
- The approval basis for each item, whether structural repair manual reference, approved data, or a separate approval
- Return-to-service entries checked for the right authority and the right scope of work
- Interior and cabin changes screened for whether they were repairs or alterations requiring approval
- Damage reports matched to the disposition and the corrective action actually recorded
- The repair map reconciled against the type design so no item sits outside a known location

What gets validated
- Each repair on the map carries an approval reference that matches the damage and the location it addresses
- Alterations are recorded as alterations, with approval data appropriate to the change and the jurisdiction
- Return-to-service entries cite work that the underlying disposition and evidence actually support
- Structural repair manual repairs stay within the limits and revision the reference cites
- No repair on the map lacks a source document a diligence reviewer would accept on its face
Evidence normally required
- Airframe logbooks and the dirty-fingerprint work packages that recorded each repair
- The current repair map or dent-and-buckle chart for the serial number
- Approval data, structural repair manual references, and any separate approvals cited
- Damage reports and engineering dispositions for repaired events
- The configuration and modification list to place alterations against the type design
Common discrepancies
- A repair logged to structural repair manual limits with no revision or reference actually recorded
- An interior change treated as a routine repair when the installation required approval as an alteration
- A damage report with a disposition but no closing return-to-service entry on file
- A repair on the airframe with no corresponding location on the repair map
What is at stake
A repair without traceable approved data forces a buyer to assume the worst: re-substantiation, or removal and rework at their cost. On an aircraft this configuration-sensitive, an alteration recorded as a routine repair can quietly break the configuration baseline that AD applicability and later work rest on. Left unaddressed, these items surface during diligence with less time and less leverage to close them.

How the work runs
Build the repair map
Collect every repair and alteration from the logbooks and packages and place each on the airframe location it addresses.
Test the approval basis
Confirm each item cites approved data, a structural repair manual reference, or a separate approval appropriate to the work.
Check the closure
Verify the return-to-service entry matches the disposition and the scope of the repair or alteration.
List and plan
Rank unsupported items and set out what each one needs to close.
What the buyer receives
- A supported exception list ranking each repair or alteration by the strength of its evidence
- A source map tying every item on the repair map to its approval and closure documents
- A closure plan naming what each unsupported item needs and where the evidence should come from
Who uses the output
- Asset managers pricing the repair history a buyer's team will scrutinize
- Records leads assembling a defensible repair map before diligence or redelivery
- Engineering deciding how to treat an alteration recorded without an approval basis
How the work fits into the transaction or program
The repair-approval review feeds the configuration picture the rest of the file depends on, because an alteration recorded as a repair distorts what the aircraft is. Its exception list flows into gap remediation while the current holder still controls the paperwork, and the settled repair map becomes part of the data room the next transaction works from.
Aircraft-specific considerations
The Global 7500 is a new-generation airframe with composite structure and an integrated cabin, so the line between a repair and an alteration is finer than on an older metal business jet. A change to seating, monuments, or the cabin management system can require approval that a straightforward dent repair does not, and the repair map has to reflect both. Because many of these aircraft have passed through a management provider rather than a single owner-operator, repair evidence is often split across handovers.
Jurisdiction-specific considerations
A Global 7500 that has operated on both an FAA and an EASA register may carry repairs approved under one system that need an acceptable basis recognized by the other. The review notes where a repair's approval basis will need supplementing for the register the aircraft is moving toward, without asserting that either authority accepts it.
Regulatory limits
The review assesses whether each repair and alteration is supported by traceable approved data and a valid closure entry. It does not approve a repair, issue or restore any approval, or make an airworthiness determination on the structure or the alteration.
What this review does not cover
- Physical inspection of the structure or the repaired areas
- Developing or approving new repair or alteration data
- Any airworthiness determination on a repair or the airframe
Specific to this review
- On composite structure the repair reference matters as much as the workmanship, because an out-of-limit repair may not be visible but still lacks a valid basis.
- Cabin and interior work is where repair-versus-alteration calls most often slip, since the installation looks routine even when the approval requirement is not.
- A repair with no location on the map is often a real repair that was recorded but never charted, which is quicker to close than a missing approval.

Frequently asked questions
How do you tell whether an interior change should have been an alteration?
By what the installation touches and how the type design treats it. A change to seating, monuments, or systems that alters the approved configuration usually needs approval as an alteration, while a like-for-like repair within limits does not. The review flags the calls that were recorded the wrong way so engineering can settle them.
