Airworthiness Directive · Amendment 39-9306 · Aerospatiale Model ATR42 Series Airplanes
Aerospatiale Model ATR42 Series Airplanes
Model ATR42 series airplanes having manufacturer's serial numbers 121 through 125 inclusive, 128 through 139 inclusive, and 141 through 143 inclusive, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Aerospatiale Model ATR42 series airplanes. This action requires replacement of the currently installed side brace pins of the main landing gear (MLG) with new pins. This amendment is prompted by a report of a ruptured pin on an in-service airplane. The actions specified in this AD are intended to prevent failure of the side brace pins and the subsequent collapse of the MLG.
