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 repetitive replacements of the weight on wheels microswitch harness subassembly with a new microswitch harness subassembly. 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 a nose wheel shimmy, which could result in the collapse of the nose landing gear during takeoff or landing and possible injury to the flightcrew and passengers.
