Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas airplane models. This proposal would require a one-time inspection for chafing of wiring in the left-hand tunnel area of the forward cargo compartment, repair if necessary, and coiling and stowing of excess wiring. This action is necessary to prevent wire chafing and subsequent shorting to structure in the forward cargo compartment, which could result in smoke or fire in the airplane. This action is intended to address the identified unsafe condition.
