Airworthiness Directive · Amendment 39-8860 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company DC-10-30, DC-10-30F (KC-10A, KDC-10), DC-10-40, DC-10-40F.
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 series airplanes and KC-10A (military) airplanes, that requires modification of the cavity vent drain tube assembly at the center wing lower auxiliary fuel tank cavity. This amendment is prompted by a report that the cavity vent tube, if not properly grounded, could act as an electrical path in the event of a lightning strike. The actions specified by this AD are intended to prevent arcing in the tank cavity and possible resulting fire.
