Airworthiness Directives; Airbus Helicopters.
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350D, AS355E, AS355F, AS355F1, AS355F2, and AS355N helicopters. This proposed AD was prompted by reports of debonding on the leading edge protection of certain part-numbered main rotor blades (MRBs). This proposed AD would require repetitively tap inspecting the MRB and, depending on the results, taking corrective action. This proposed AD would also prohibit installing an affected MRB on any helicopter unless its requirements are met. These actions are 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.
Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
The FAA is superseding Airworthiness Directive (AD) 2021-25-03 for all Rolls-Royce Deutschland Ltd & Co KG (RRD) Model Trent 7000-72 and Trent 7000-72C engines. AD 2021-25-03 required operators to revise the airworthiness limitation section (ALS) of their existing approved continuous airworthiness maintenance program by incorporating the revised tasks of the applicable time limits manual (TLM) for each affected engine model. Since the FAA issued AD 2021-25-03, the manufacturer again revised the TLM to introduce new or more restrictive tasks and limitations and associated thresholds and intervals for life- limited parts, which prompted this AD. This AD requires revising the ALS of the operator's existing approved engine maintenance or inspection program, as applicable, to incorporate new or more restrictive tasks and limitations and associated thresholds and intervals for life-limited parts, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
