The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model H160-B helicopters. This proposed AD was prompted by reports of a fully discharged personal locator beacon (PLB) battery installed on an emergency life-raft system (ELRS), as well as a report where the ropes connecting the two ELRS to the PLB were not correctly attached. This proposed AD would require performing a functional test of the PLB and inspecting the rope connection to the ELRS. Depending on the results of the functional test, this proposed AD would require performing the functional test again or replacing affected parts, and depending on the results of the rope inspection, correctly attaching the wrist strap of the PLB to the ELRS rope. This proposed AD would also prohibit the installation of a certain part- numbered PLB and the rope connection to the ELRS, unless certain requirements are met. The FAA is proposing this AD to address the unsafe condition on these products.
The FAA is superseding Airworthiness Directive (AD) 2024-08- 05, which applied to certain Airbus SAS Model A330-200, A330-200 Freighter, and A330-300 series airplanes; and Model A330-841 and A330- 941 airplanes. AD 2024-08-05 required revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations. Since the FAA issued AD 2024-08- 05, the FAA has determined that additional new and more restrictive airworthiness limitations are necessary. This AD continues to require certain actions in AD 2024-08-05 until the existing maintenance or inspection program, as applicable, is revised to incorporate the new and more restrictive airworthiness limitations. The FAA is issuing this AD to address the unsafe condition on these products.
The FAA proposes to supersede Airworthiness Directive (AD) 2025-06-01, which applies to all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes.
