ATR - GIE Avions de Transport R gional Airplanes
This AD applies to ATR - GIE Avions de Transport R gional ATR72-101, ATR72-102, ATR72-201, ATR72-202, ATR72-211, ATR72-212, ATR72-212A.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Aerospatiale Model ATR72 series airplanes, that requires modification of the pitch uncoupling mechanism of both elevators. This amendment is prompted by reports of fatigue cracking of the pitch uncoupling mechanism and the torque tube of the elevator. Failure of the pitch uncoupling mechanism due to fatigue cracking could result in the uncommanded uncoupling of the elevators. The actions specified by this AD are intended to prevent such fatigue cracking and subsequent uncommanded uncoupling of the elevators, which could result in reduced controllability of the airplane.
