Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This proposal would require an inspection of the wiring in the fuel control panel of the wings for chafing damage and for proper routing of the wiring; and corrective action(s), if necessary. This action is necessary to prevent chafing of the wiring in a cutout area in the wing fuel control panel due to improperly routed wiring, which could result in electrical arcing in an abnormal fuel vapor zone and consequent possible ignition of the fuel vapor. This action is intended to address the identified unsafe condition.
