Airworthiness Directives; Rolls-Royce Corporation (RRC) AE 3007A Series Turbofan Engines
Tradução automática local · Idioma original da fonte
Resumo
The FAA proposes to adopt a new airworthiness directive (AD) for RRC AE 3007A series turbofan engines. This proposed AD would require removing or performing initial and repetitive eddy current inspections (ECIs) or surface wave ultrasonic testing (SWUT) inspections on high-pressure turbine (HPT) stage 2 wheels for cracks. This proposed AD also reduces the approved life limits of certain HPT stage 2 wheels. This proposed AD results from reports of cracked HPT stage 2 wheels. We are proposing this AD to prevent uncontained failure of the HPT stage 2 wheel and damage to the airplane.
