Airworthiness Directives; British Aerospace Jetstream Model 3201 Airplanes

This document proposes to adopt a new airworthiness directive (AD) that would apply to all British Aerospace Jetstream Model 3201 airplanes. The proposed AD would require accomplishing both a routine visual inspection and either a detailed visual inspection or x-ray inspection of the main landing gear (MLG) bay auxiliary spar booms for cracks or fuel leaks on both the left and right sides of the airplane. The proposed AD would also require obtaining and incorporating repair procedures for the MLG bay auxiliary spar where fuel leaks or cracks are found. The proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for the United Kingdom. The actions specified by the proposed AD are intended to prevent wing failure caused by cracks or fuel leaks in the area of the MLG bay auxiliary spar booms, which could result in loss of control of the airplane.
