Summary
This document proposes the adoption of a new airworthiness directive (AD), applicable to a certain McDonnell Douglas Model DC-10-30 airplane. The proposal would require an inspection of the power feeder cable assembly of the auxiliary power unit (APU) for chafing, correct type of clamps, and proper clamp installation; and corrective actions, if necessary. This action is necessary to prevent the loss of the APU generator due to chafing of the generator power feeder cables, and consequent electrical arcing and smoke/fire in the APU compartment. This action is intended to address the identified unsafe condition.
