Airworthiness Directive · Amendment 39-11272 · Aerospatiale Model ATR42-300 and ATR42- 320 Series Airplanes
Aerospatiale Model ATR42-300 and ATR42- 320 Series Airplanes
Model ATR42-300 and ATR42-320 series airplanes, serial numbers 3 through 59 inclusive; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Aerospatiale Model ATR42-300 and ATR42-320 series airplanes, that requires a one-time inspection for cracking of a fastener hole located on the lower surface of the outer wing, and repair, if necessary; and cold working of the hole and installation of a new fastener in the hole. 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 fatigue damage on the outer wing and consequent reduced structural integrity of the wing.
