Case note 02 · ATA 25 interiors & ATA 32 wheel and brake

Two part families, one routing, and one file that had to close

A holder asked for cabin interior details and wheel and brake components in the same programme. The processes sat in different workshops; the revision state, the first article plan and the traceability file did not. This note is about the second half, because that was the half that decided whether the programme ran cleanly.

Names and counts are withheld. The approval holder, the aircraft programme, the qualified facilities, part numbers and quantities do not appear here. Nothing in this note is a catalogue, an availability statement or an offer of parts for sale — the work was built against issued requirements, and the customer signed the release under its own approval.

What the brief contained

Three groups of work, each judged against a different set of requirements, all placed under one programme.

Work groups, controlling data and returned evidence
Work groupBuilt toEvidence returned
Seat and cabin hardwareThe holder’s drawing and revision, including finish and markingDimensional record, material certificates, surface treatment record
Moulded panels and soft trimThe holder’s specification and its flammability, smoke and toxicity evidenceFST evidence, lot traceability, first article report where the plan called for one
Steel brake and wheel componentsThe requirements issued for the programme, including the accessories named in themDimensional and material records, assembly and hardware traceability

The table describes the shape of one programme, not a list of parts we hold or can quote from stock. A new programme starts from the drawing status you send.

Why both families stayed on one routing

The workshops were different. Keeping three things common is what made the difference.

One revision state

A change to a drawing applied to the whole programme rather than drifting between workshops. The incoming inspection had a single set of numbers to check at despatch.

One first article plan

The AS9102 submission was planned across both families before any production was released, so acceptance was written down once, for the programme, rather than negotiated family by family.

One place for exceptions

Nonconformance, concessions and change control ran through the same window. That is usually where a two-family programme comes apart — not in the machining.

Where the responsibility stayed

Splitting the work across two families did not move any of these answers across the table.

Responsibility split in this programme
QuestionAnswer
Who held the approvalThe customer, for both families. We held none and issued no release document.
Who manufacturedQualified partner facilities in China, selected and routed to the issued requirements.
Who accepted the first articleThe customer, in writing, before production was released.
Who signed the releaseThe customer, under its own approval, after its own final inspection.
What was not in the briefFinished parts offered for sale, a stock position, a catalogue to browse, or a quoted delivery date before the first article plan existed.

Before you copy this shape of programme

The useful output of a case note is a checklist, not a promise that it will work the same way for you.

  • Obtain a written release path determination for the registry you intend to sell into. A case note is not an installability finding.
  • Confirm the approval basis family by family. A cabin trim item and a brake component are not substantiated in the same way, even when they sit on one purchase order.
  • Agree the document set for each family before the first article is cut, and name who signs each record.
  • Decide whether any output will be handed over at an intermediate process stage; that changes both the paperwork and who performs final inspection.

Records are not approvals. A first article report, a certificate of conformity and a signed traveller describe what was made and checked. They do not replace the release document issued under an approval by its holder. Seehow those records are produced and kept.

Send the drawing status for the families you need

List the part families, the operations you intend to keep and the state of registry. The first written reply sets out the routing, the first article plan and the document set — or tells you plainly that the release path does not work.
