The FAA is asked to review and revise, in coordination with engine manufacturers, air carriers, and certified repair stations, the existing guidance, equipment, inspection procedures, inspector training (including electronic and visual aids), and supervision for nickel-cadmium plating and other plating processes that could cause liquid metal embrittlement of high-energy rotating engine parts.
