Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 767 series airplanes. This proposal would require a one-time inspection to detect discrepancies of the wire expando sleeve of the wire bundles adjacent to the landing gear control lever module; certain follow-on actions and repair, if necessary; and wrapping the wire expando sleeve with tape or zippertubing and tape. This proposal is prompted by reports indicating that the landing gear failed to extend on an in-service airplane, and that the cable of the landing gear control lever was severed on a second in-service airplane. The actions specified by the proposed AD are intended to prevent interference and consequent arcing between the landing gear control lever and the wire bundles adjacent to the landing gear control lever module, which could result in inability to extend the landing gear prior to landing.
