Action
Notice of proposed rulemaking (NPRM).
Summary
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model EC155B1 helicopters. This proposed AD was prompted by a report of difficulties when jettisoning the co- pilot door during non-scheduled maintenance. This proposed AD would require a functional check of the pilot and co-pilot door jettisoning system and corrective actions if necessary, as specified in a European 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.
