Summary
This document revises an earlier proposed airworthiness directive (AD), applicable to certain Fokker Model F28 Mark 0100 series airplanes, that would have required reinforcing the lower right-hand wing skin at the fueling adapter. That proposal was prompted by results of tests, which revealed that fatigue cracks can develop in the lower right-hand wing skin at the attachment bolt holes of the fueling adapter. This action revises the proposed rule by citing the latest service information. This action also revises the applicability of the proposed AD. The actions specified by this proposed AD are intended to prevent reduced structural capability of the wing and fuel leakage.
