ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Model EC 130 B4 and EC 130 T2 helicopters. This proposed AD was prompted by a report of heavy damage on the fenestron due to the loss of the tail rotor (TR) blade, which broke at the TR hub tension-torsion bar (tension-torsion bar). This proposed AD would require inspecting the tension-torsion bar and, depending on the inspection results, taking corrective actions. This proposed AD would also prohibit performing maintenance using certain maintenance manuals. These proposed 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. DATES: The FAA must receive comments on this NPRM by June 23, 2025.
