## Abstract

The FAA is adopting a new airworthiness directive (AD) for all The Boeing Company Model DC-10-10 and DC-10-10F airplanes, Model DC-10- 15 airplanes, Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) airplanes, Model DC-10-40 and DC-10-40F airplanes, Model MD-10-10F and MD-10-30F airplanes, and Model MD-11 and MD-11F airplanes. This AD was prompted by reports of cracked floor beams and floor beam supports in the area of the overwing exit doors located at certain stations (STA). This AD requires an inspection of the overwing floor beams for any repair, repetitive inspections of the overwing floor beams and floor beam supports at certain STA on the left and right sides for any crack, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
