Airworthiness Directive · Amendment 39-9702 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company MD-11, MD-11F.
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 McDonnell Douglas Model MD-11 series airplanes, that requires either replacement or modification of the inboard and outboard flap actuators. This amendment is prompted by a report of failure of the piston rod of the inboard flap actuator due to a manufacturing process error. The actions specified by this AD are intended to prevent failure of the piston rod, which could result in uncommanded flap extension and could lead to an asymmetric flap configuration, which could reduce controllability of the airplane.
