Airworthiness Directives; Pilatus Britten-Norman Limited BN-2 and BN2A Mk. III Series Airplanes

摘要

This document proposes to adopt a new airworthiness directive (AD) that would apply to all Pilatus Britten-Norman (Pilatus Britten- Norman) Limited BN-2 and BN2A Mk. III series airplanes. This proposed AD would require you to inspect the universal joints on the pilot's and co-pilot's control column to determine the diameter of the shaft. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by this proposed AD are intended to correct the installation of universal joints that have the wrong-sized shaft, which could result in failure of the pilot's and/or co-pilot's control column. Such failure could lead to loss of control of the airplane.
