Airworthiness Directives; Pilatus Britten-Norman Ltd. (Formerly Britten-Norman) BN2A MK. 111 Series Airplanes

This amendment revises Airworthiness Directive (AD) 86-07-02, which currently requires repetitively inspecting the junction of the torque link lug and upper case of the main landing gear (MLG) torque link assemblies for cracks on Pilatus Britten-Norman Ltd. (Pilatus Britten-Norman) BN-2A, BN-2B, BN-2T, and BN2A MK. 111 series airplanes, and replacing any part found cracked with a like part. This AD removes from the applicability the BN-2A, BN-2B, and BN-2T series airplanes, and retains the repetitive inspection and replacement (if necessary) requirements of AD 86-07-02 for the BN2A MK. 111 series airplanes. This AD results from the Federal Aviation Administration's determination that additional AD action needs to be taken on the BN-2A, BN-2B, and BN-2T series airplanes. This additional action will be addressed in a separate AD. The actions specified by this AD are intended to prevent failure of the main landing gear caused by cracks in the torque link area, which could lead to loss of control of the airplane during landing operations.
