Airworthiness Directive · Amendment 39-8871 · Various Airplanes
Various Airplanes
This AD applies to Various F.28 Mark 0100.
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 Fokker Model F-28 Mark 0100 series airplanes, that requires inspection, necessary repair, and modification of the engine mount shear shelf webs. This amendment is prompted by reports of interference between the engine mount shear shelf web and the fixed cowl mid and aft hooks, which caused fatigue cracks to occur in the web. The actions specified by this AD are intended to prevent fatigue cracking and other damage to the structure of the shear shelf web, which subsequently could lead to loss of the engine mounting structure.
