## Abstract

The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model EC155B1 helicopters. This AD was prompted by a report of difficulties when jettisoning the co-pilot door during non-scheduled maintenance. This AD requires 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 incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
