Airworthiness Directives; Airbus Helicopters

FAA / Federal Register · 2022-16776

The FAA proposes to adopt a new airworthiness directive (AD) for Airbus Helicopters Model SA-365N, SA-365N1, AS-365N2, AS 365 N3, EC 155B, and EC155B1 helicopters. This proposed AD was prompted by reports of the cockpit doors failing to open after ditching with inflated floats on certain helicopters equipped with an emergency flotation system (EFS). This proposed AD would require revising the existing Rotorcraft Flight Manual (RFM) for your helicopter, installing placards, and depending on your model helicopter, modification of the jettisoning system, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
