Airworthiness Directive · Amendment 39-9827 · Fokker Services Airplanes
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 replacement of certain rudder horn assemblies with a new assembly. For certain airplanes, the amendment also requires replacement of certain rudder control rods with a new rod. This amendment is prompted by reports of cracked rudder horns and a cracked rudder control rod, caused by impact overload. The actions specified by this AD are intended to prevent such an overload and consequent cracking of the subject parts, which could result in reduced structural integrity of the rudder horn assembly or loss of rudder control; this condition could lead to reduced controllability of the airplane.
