Airworthiness Directives; Pilatus Britten-Norman Limited BN2T and BN2T-4R Series Airplanes

Краткое содержание

This amendment adopts a new airworthiness directive (AD) that applies to all Pilatus Britten-Norman Limited (Pilatus Britten-Norman) BN2T and BN2T-4R series airplanes. This AD requires you to repetitively inspect the left and right engine-mounting frame for cracks and replace the frame if cracks are found. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by this AD are intended to detect and correct cracks in the left and right engine- mounting frame, which could lead to engine mount failure. Such failure could result in separation of the engine from the airplane.
