Abstract
The FAA is adopting a new airworthiness directive (AD) for all Fokker Services B.V. Model F28 Mark 0070 and 0100 airplanes. This AD was prompted by a report that corrosion was found on the horizontal flange on the front spar lower boom, between the rebate strap and the lower boom, and resulted in bulging. This AD requires doing a detailed visual inspection to detect any bulging, loose, and missing countersunk fastener heads at the left-(LH) and right-hand (RH) outer wing lower skin of the front spar between certain wing stations, and applicable on-condition actions, as specified in a European Union Aviation Safety Agency (EASA), which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
