If you’re evaluating providers, the most reliable indicators of “OEM approvals + strong traceability” are:

1. Current OEM approval letters/listings for the exact aircraft/gear model
2. FAA/EASA/CAA regulatory approvals for the specific facility
3. Serialized part genealogy and material cert retention
4. Repair scheme approval control and deviation handling
5. NDT, plating, and machining process traceability
6. Audit history / AS9110 or equivalent quality certification
