Airworthiness Directives; Airbus SAS Airplanes

摘要

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and A350-1041 airplanes. This proposed AD was prompted by a report the thrust reverser and pylon thermal blankets were found damaged due to air leaking from the pre- cooler exchanger (PCE). This proposed AD would require repetitively testing the PCE for air leaks and reporting the results, and depending on findings, replacing the PCE and inspecting the thermal blankets for damage, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
