## Abstract

The FAA is superseding Airworthiness Directive (AD) 2014-12- 12, which applied to certain Airbus Helicopters Model EC120B and EC130B4 helicopters. AD 2014-12-12 required inspecting and, if necessary, replacing parts of the sliding door star support attachment assembly. This AD requires modifying the sliding door star support stringer as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). This AD was prompted by several incidents involving helicopter left-hand side doors (both swinging and sliding) that revealed weaknesses in the locking mechanism. The FAA is issuing this AD to address the unsafe condition on these products.
