Programme case notes
A case note on a contract manufacturing site has a narrow job: show where the work stopped, which records changed hands at that point, and who closed the file with a signature. It is not a customer list, a catalogue, or a claim about how many parts moved.
Why no names appear here. The approval holder, the aircraft programme, the qualified facility, part numbers and batch quantities are withheld in both notes. Publishing them would describe somebody else’s supply chain rather than our side of the work. What remains is the part a prospective holder can actually reuse: the shape of the brief, the handover boundary and the document set.
A holder with its own downstream operations asked for carbon discs at one defined process stage, together with the metallic items used at the next operation. The interesting part was the document set at that exact boundary.
Cabin interior details and wheel and brake components were requested in the same programme. The processes sat in different workshops; the revision state, the first article plan and the traceability file did not.
A programme starts with a drawing status, a part family, the stage or operations you will keep, and the registry you intend to sell into. The first written reply sets out the route and the records.
The withheld column is not an omission. It is the same boundary the site applies everywhere else.
| Item | Position |
|---|---|
| Published | The shape of the brief, the handover boundary, which records changed hands, who performed the remaining operations, and who signed the release. |
| Approval holder, aircraft programme and facility identity | Withheld. Naming them would describe somebody else’s supply chain, not the manufacturing discipline on this site. |
| Part numbers, quantities and prices | Withheld. There is no catalogue, no published part count and no stock position behind these notes. |
| Process parameters | Withheld. Numerical density values, treatment chemistry, thermal profiles, rivet and fixture settings and batch process cards stay with the qualified facility and the technical agreement. |
| Release documents | Not reproduced. A release document is issued under an approval by the holder of that approval; these notes describe records that support a signature, never a substitute for one. |
A programme that worked for one holder under one registry is not evidence that the same route works for yours.
Records are not approvals. A certificate of conformity, a first article report and a signed process traveller describe what was made and checked. None of them is an airworthiness release document, and none of them is issued under an approval we hold. Seehow the records are produced and kept before you plan your own file.
Send the drawing status, the part families, the operations you intend to keep, and the state of registry. The first written reply covers the routing, the records for that boundary and whether the release path works at all.
