🚁Proposed Airworthiness Directives for Airbus Helicopters by FAA

The FAA proposes to supersede Airworthiness Directive (AD) 2019-19-13, which applies to certain Airbus Helicopters Model EC225LP helicopters. AD 2019-19-13 requires determining the total hours time- in-service (TIS) of the free wheel shafts of certain main rotor gearboxes (MGBs), replacing the MGB or right-hand side (RH) free wheel shaft, installing placard(s), and revising the Rotorcraft Flight Manual (RFM) for the helicopter. Since the FAA issued AD 2019-19-13, an additional part-numbered MGB has been identified to have the same unsafe condition and the FAA determined that additional changes are necessary. This proposed AD would require the actions of AD 2019-19-13 and, expand the applicability by adding the additional part-numbered MGB, change the requirement to determine the total hours TIS of a certain free wheel shaft, require repetitive replacement of the MGB or the RH free wheel shaft, change the requirements for who can replace parts, and expand the parts installation limitation conditions. The FAA is proposing this AD to address the unsafe condition on these products.

🚁New Airworthiness Directive for Airbus Helicopters Model AS332L

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS332L helicopters. This AD was prompted by a determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the airworthiness limitations section (ALS) of the existing maintenance manual (MM) or instructions for continued airworthiness (ICAs) and the existing approved maintenance or inspection program, as applicable, 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.

🚁New Airworthiness Directive for Airbus Helicopters Effective May 2025

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model SA330J helicopters. This AD was prompted by the determination that new or more restrictive airworthiness limitations are necessary. This AD requires revising the existing maintenance records by incorporating new or more restrictive airworthiness limitations, 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.
