Suspected Unapproved Parts Details
During the wheel and brake overhaul of MSN XXX, a number of discrepancies were identified. The non-compliant findings are:
- Pre-production Rotor Drive Keys (RDKs) found in-service (P/N 2615162 XA)
- Modified pre-production wheel assemblies found in-service (P/N 2615101-3 XA)
- Quality Escape RDKs found in-service
Issue: Pre-production parts (Rev XA) are not certified. In addition, differences between pre-production and production parts may lead to difference in braking performance.
2615101-1 parts result in a potentially unsafe condition (IMPORTANT NOTE: There is no evidence that any -1 Rev A or -1 Rev-XA wheels were delivered or found in-service).
Recommendation: Any pre-production RDKs (P/N 2615162 XA) and pre-production wheel assemblies (P/N 2615101-3 XA) should be removed from in-service aircraft.
List of affected parts :
- 2615162 XA
