Airworthiness Directives; Pilatus Britten-Norman Ltd. BN-2, BN- 2A, BN-2B, and BN-2T Series Airplanes

This amendment adopts a new airworthiness directive (AD) that applies to all Pilatus Britten-Norman Ltd. (Pilatus Britten-Norman) BN- 2, BN-2A, BN-2B, and BN-2T series airplanes. This AD requires replacing the attachment bolts, nuts and washers of the lower fitting of the main landing gear (MLG), and adjusting the torque values of the nuts. 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 prevent the bolts that attach the lower fitting of the MLG to the nacelle from becoming threadbound, which could result in structural failure of the MLG with consequent loss of control of the airplane during takeoff, taxi, or landing operations.
