Airworthiness Directives; Airbus Helicopters

FAA / Federal Register · 2021-26604

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS355NP helicopters. This AD was prompted by a report of mechanical deformation found on the protective cover (also referred to as switch guard) of the "SHEAR" control pushbutton installed on a co-pilot collective stick of a Model EC225LP helicopter, caused by incorrect handling; due to having an identical design switch guard installed on the pilot collective stick, Model AS355NP helicopters are also affected. This AD requires replacement of the protective cover of the "SHEAR" control pushbutton, and re- identification of the pilot collective stick, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
