Start with the approved part definition
Aircraft structural parts are defined by the design authority and applicable program documents. A machining supplier should review the released drawing, material, quantity, interfaces and required evidence. This page does not claim a particular aircraft approval or specialized structural-part capability.
Identify the features and records that matter
Mark datums, mounting interfaces, critical dimensions and surface requirements. Specify material grade, source documentation, inspection method and any customer-specific records. Identify whether the order is a prototype, qualification build or production release.
- Provide the controlled model and drawing revision.
- State material, quantity and build stage.
- List critical features and inspection evidence.
- Confirm manufacturing site and outside operations.
- Verify program approval and certification requirements separately.
Separate machining from aircraft approval
Machining completion does not approve a structural part for flight. The design authority and responsible program organization determine verification, conformity and release requirements. Confirm current supplier and site qualifications before award.

Keep changes under control
Record approved deviations and use the same revision for quote, production and inspection. Reassess if design, material, site or program requirements change.
