The FAA and an EASA approved Part-145 maintenance organisation have informed EASA about a suspected unapproved part Air Cycle Machine with the P/N 2206400-2 and S/N 27-5439, that originated in China, claiming that the subject part had been overhauled by the EASA approved Part 145 maintenance organisation and issued the relevant documentation, in December 2017.

Further investigation revealed that the subject part was not repaired by the EASA approved Part 145 maintenance organisation since no repair records of this unit’s serial number/release documentation appears in their system.

Therefore, it was concluded that the Authorized Release Certificates (EASA Form 1, FAA Form 8130-3 and CAAC ACC-038), the Component Repair Report and the Material Traceability Certification were forged.
