Airworthiness Directives; McDonnell Douglas Model MD-11 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model MD-11 series airplanes, that requires a one-time detailed visual inspection of the wire bundle installation behind the first observer's station to detect damaged or chafed wires; and corrective action, if necessary. This amendment is prompted by a report indicating that the wire bundle contained in the feedthrough behind the first observer's station was contacting the bottom portion of the feedthrough. The actions specified by this AD are intended to prevent such contact, which could cause cable chafing, electrical arcing, smoke, or fire in the cockpit.
