Airworthiness Directives; British Aerospace Model HS 748 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace Model HS 748 series airplanes. This action requires a visual inspection to detect fatigue cracking or loose fitting stress pads of the aileron operating arm brackets; and follow- on corrective actions, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to detect and correct fatigue cracking in the flanges of the aileron operating arm brackets, which could result in failure of the aileron operating arm brackets, failure of the aileron control system, and consequent reduced controllability of the airplane.
