Airworthiness Directives; Airbus Helicopters (Previously Eurocopter France)

摘要

We propose to supersede Airworthiness Directive (AD) 2014-12- 12 for Airbus Helicopters (previously Eurocopter France) Model EC130B4 and Model EC120B helicopters. AD 2014-12-12 currently requires inspecting and, if necessary, replacing parts of the sliding door star support attachment assembly. This proposed AD would expand the applicability and provide revised instructions for reinforcing the sliding door. These proposed actions are intended to prevent failure of the sliding door star support attachment, which could inhibit the operation of the sliding door from the inside, delaying the evacuation of passengers during an emergency.
