Airworthiness Directives; British Aerospace BAe Model ATP Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace BAe Model ATP airplanes, that requires a one-time inspection to detect corrosion, wear, or damage of the operating mechanism of the forward door of the main landing gear (MLG); operational inspections to ensure smooth operation of the MLG operating mechanism; and follow-on actions. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent partial seizure of the forward door of the MLG operating mechanism, which could result in the inability to lower or retract the MLG.
