Airworthiness Directive · Amendment 39-8910 · The Boeing Company Airplanes
The Boeing Company Airplanes
This AD applies to The Boeing Company 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) that is applicable to certain McDonnell Douglas Model MD-11 and MD-11F series airplanes. This action requires deactivation of the Visual Omnidirectional Receiver/Localizer (VOR/LOC) option by revising the program pin wiring for the Flight Management Computer/Flight Control Computer (FMC/FCC). This amendment is prompted by reports of uncommanded roll mode changes on these airplanes during takeoff and landing due to incorrect initialization of VOR/LOC logic within the FMC. The actions specified in this AD are intended to prevent the airplane from deviating from its intended flight path due to an uncommanded change in the course of direction.
