Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Pilatus Britten-Norman Limited (Pilatus Britten-Norman) BN-2, BN-2A, BN-2B, and BN-2T series airplanes. This proposed AD would require you to repetitively inspect the inboard brackets of the elevator outboard hinge for loose rivets, structural damage, or cracks and replace any suspect bracket. The proposed AD would also require you to replace the hinge bracket at a certain time period if no discrepancies are found. This replacement includes modifying this area and installing modified brackets. This replacement allows you to increase the time period between inspections (reduce the number of repetitive inspections). 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 detect and correct inboard brackets of the elevator outboard hingewith loose rivets, structural damage, or cracks. Such conditions could cause the outboard elevator to become loose with a consequent reduction in elevator and airplane control.
