Structural repairs
ATR 72 structural repair records and repair map review
This review assembles an ATR 72's structural repair history into a repair map and confirms each repair traces to approved data with its damage report and any recurring inspection captured. A records specialist runs it before a transaction, after a repair campaign, or when corrosion and repair history has built up across a long service life. It checks repair maps, damage reports, structural repair manual references, and the approval basis for each repair, then flags repairs without a data reference or a required follow-up. You receive a consolidated repair map, a list of repairs missing approval or inspection evidence, and the source references behind each.
When this review is needed
- An older ATR 72 has accumulated repairs and corrosion history with no consolidated repair map.
- A structural repair was performed and its approval basis or recurring inspection is unclear in the record.
- A buyer needs the structural repair history mapped and substantiated before pricing the airframe.
- A damage report exists but the repair that closed it cannot be found, or the reverse.
The problem
Structural repairs are recorded across damage reports, work orders, and approval data that rarely sit together, so no single document shows the airframe's repair state. A repair done under a repair-manual reference is straightforward, but one that needed engineering approval leaves a data reference that has to be located and matched. On an ATR 72 in humid regional operation, corrosion-driven repairs accumulate, and any repair that carries a recurring inspection but never had it recorded becomes an open obligation the records do not surface.
What gets reviewed
- Every structural repair located across damage reports, work orders, and approval data
- Each repair traced to its structural repair manual reference or engineering approval
- Damage reports reconciled to the repairs that closed them
- Recurring inspections attached to repairs confirmed against the inspection record
- Corrosion findings and their repairs mapped to the airframe zones affected
- Overlapping or adjacent repairs identified so their interaction is visible

What gets validated
- Each repair references approved or acceptable data appropriate to the damage and location
- Every damage report has a corresponding repair, and every repair a damage or finding origin
- Repairs that carry a recurring inspection show that inspection in the record at interval
- Repair locations reconcile to the airframe zones and the structural repair manual areas
- Repairs needing engineering approval carry the substantiation the approval rests on
Evidence normally required
- The structural repair records and any existing repair map
- Damage reports and the work orders that closed them
- Structural repair manual references and engineering approval data
- The inspection record for any recurring inspections tied to repairs
Common discrepancies
- A repair performed with no approved-data reference to substantiate it
- A recurring inspection required by a repair but never recorded at interval
- A damage report with no repair record closing it out
- Corrosion repairs clustered in a zone with no consolidated view of their extent
What is at stake
A repair without traceable approval data can force re-substantiation or, at worst, rework, and a missing recurring inspection is a live continued-airworthiness obligation the operator is not tracking. Without a consolidated map, a buyer cannot judge the airframe's repair burden, and overlapping repairs in one area may go unnoticed until they interact at a heavy check.

How the work runs
Gather the repairs
Collect every structural repair from damage reports, work orders, and approval data.
Trace the basis
Match each repair to its manual reference or engineering approval and substantiation.
Build the map
Locate each repair by airframe zone and reconcile it to the damage that caused it.
Flag the obligations
List repairs missing approval data or a recurring inspection the record should carry.
What the buyer receives
- A consolidated structural repair map for the airframe
- A list of repairs missing approval data or a required recurring inspection
- The source references and approval evidence behind each mapped repair
Who uses the output
- Records teams building a defensible structural history for the airframe
- Engineering judging repairs that lack a traceable substantiation basis
- Asset and acquisition teams pricing the airframe's repair and corrosion burden
How the work fits into the transaction or program
The repair map underpins any structural assessment and feeds the heavy-check planning that depends on knowing where the airframe has been repaired. A repair without approval data routes to remediation, and a repair carrying an untracked recurring inspection feeds straight into the continued-airworthiness obligations the operator has to manage.
Aircraft-specific considerations
ATR 72 airframes in coastal and humid regional operation carry a heavier corrosion and structural-repair burden than a comparable narrowbody, so repair density in the lower fuselage, wing, and gear-bay zones runs high. The review maps that corrosion-driven history carefully, because clustered repairs in one zone and the recurring inspections they carry are the items most likely to have detached from the record.
Jurisdiction-specific considerations
A structural repair approved under one authority does not automatically carry acceptance to another, so an ATR 72 changing register may need certain engineering-approved repairs validated in the receiving system. The review flags where a repair's approval basis will need supplementary acceptance after transfer.
Regulatory limits
The review consolidates and traces the structural repair record. It does not approve a repair, develop repair data, or determine that the repaired structure is airworthy, all of which remain with the appropriate authority and design approval holder.
What this review does not cover
- A physical inspection or assessment of any repaired structure
- Developing or approving structural repair data
- Any airworthiness determination on the repaired airframe
Specific to this review
- A repair carrying a recurring inspection is a live obligation, so the untracked ones are the highest-value finding in this review.
- Repairs live in damage reports, work orders, and approval data separately, so the map is the first document that shows the airframe whole.
- Humid regional operation clusters ATR 72 corrosion repairs by zone, where their interaction only shows at a heavy check.

Frequently asked questions
Why does the repair map matter more than the individual repair records?
Individual records show one repair at a time. The map shows the airframe whole, which is where clustered repairs, corrosion-prone zones, and interacting repairs become visible. It is also what a buyer and a heavy-check planner both need to judge the airframe's repair burden.
