Summary
This action withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) to supersede an existing AD, applicable to certain Gulfstream Aerospace Corporation Model G-1159 airplanes. The existing AD requires an inspection to detect cracks or corrosion in the wing structure in the area of Fuselage Station (FS) 452 inboard clothespin attachment fitting, and repair if necessary. The proposed AD would have required repetitive inspections to detect corrosion or cracks in the forward and aft wing attach fittings at FS 345 and 452, respectively, and adjacent wing beam and wing plank areas, and repair if necessary; and the application of corrosion protection treatment. Since the issuance of the NPRM, the Federal Aviation Administration (FAA) has received new data that indicate the aircraft maintenance manual has been revised to include additional inspections that address the unsafe condition detailed in the NPRM and that the full fleet is in compliance with the inspection and applicable repair required by the existing AD. Accordingly, the proposed rule is withdrawn.
