Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-10-10, -10F, -15, -30, -30F (KC-10A and KDC-10), -40, and -40F airplanes; and certain Model MD-10-10F and -30F airplanes. This proposal would require inspections for cracking and corrosion of the bolt assemblies and bushings on the hinge fittings of the inboard and outboard flaps of the left and right wings, and follow-on and corrective actions. This action is necessary to prevent failure of the bolt and bushing that attach the hinge fitting to the flap, which could result in loss of the flap and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
