Aerospatiale Model ATR42-300 and -320, and Model ATR72 Series Airplanes
Model ATR42-300 and -320 series airplanes, on which Aerospatiale Modification 1696 (reference Avions de Transport Regional Service Bulletin ATR42-71-0010) has not been accomplished; and Model ATR72-101, -201, -102, -202, -211, and -212 series airplanes, on which Aerospatiale Modification 3742 (reference Avions de Transport Regional Service Bulletin ATR72-71-1006) has not been accomplished; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Aerospatiale Model ATR42-300 and -320, and Model ATR72 series airplanes, that requires modification of the engine fuel drainage system. 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 fuel from overflowing into the engine nacelle, which could result in a fire in the nacelle.
