Fokker Services Airplanes
This AD applies to Fokker Services F27 Mark 100, F27 Mark 200, F27 Mark 300, F27 Mark 400, F27 Mark 500, F27 Mark 600, F27 Mark 700.
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 all Fokker Model F27 Mark 100, 200, 300, 400, 500, 600, and 700 series airplanes, that requires an inspection to detect cracking of the torque tube assembly of the left-hand (LH) elevator and surrounding structure; and to detect loose or sheared rivets in that assembly. This amendment also requires either replacement or repair of discrepant parts, as appropriate. This amendment is prompted by a report of fatigue cracking found on the torque tube support of the LH elevator. The actions specified by this AD are intended to ensure that cracking is detected and corrected in a timely manner so as to prevent failure of the torque tube or its support structure, which could result in reduced controllability of the airplane.
