Airworthiness Directive · Amendment 39-12803 · McDonnell Douglas Model MD-11 and -11F Airplanes
McDonnell Douglas Model MD-11 and -11F Airplanes
Model MD-11 and -11F airplanes listed as Group 1 or Group 2 airplanes in Boeing Alert Service Bulletin MD11-57A067, including Appendices A and B, dated July 10, 2002; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 and 11F airplanes. This action requires a one-time inspection to detect loose preload-indicating (PLI) washers or cracked or corroded nuts of the lower bolts of the inboard flap outboard hinge, and replacement with new parts if necessary. This action is necessary to detect and correct loose PLI washers or cracked or corroded nuts of the lower bolts of the inboard flap outboard hinge, which could result in separation of the inboard flap outboard hinge from the wing structure and consequent reduced controllability of the airplane.
