Airworthiness Directive · Amendment 39-9076 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company DC-10-10, DC-10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A, KDC-10), DC-10-40, DC-10-40F, MD-11, MD-11F.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-10-10, -15, -30, and -40 series airplanes, KC-10A (military) airplanes, and Model MD-11 series airplanes, that requires the installation of retainers and supports at the lateral control mixer bracket on the center of the wing rear spar of the airplane. This amendment is prompted by an analysis conducted by the manufacturer, which revealed that failure of a lateral control mixer bracket could result in uncommanded deployment of the spoiler. The actions specified by this AD are intended to prevent inadvertent asymmetric deployment of the spoiler, which may lead to reduced controllability of the airplane.
