Summary
The FAA withdraws a notice of proposed rulemaking (NPRM) that proposed a new airworthiness directive (AD) for certain McDonnell Douglas transport category airplanes. The proposed AD would have required replacement with new, improved parts of the inboard flap, outboard hinge, forward attach bracket, and lower attach bolt assemblies. The proposed AD also would have required an inspection for certain parts, and related investigative and corrective actions if necessary. Since the proposed AD was issued, we have confirmed data indicating that an existing AD adequately addresses the unsafe condition. Accordingly, the proposed AD is withdrawn.
