Summary
This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Boeing Model 767-300 series airplanes. This proposal would require a one-time general visual inspection to find chafing and determine adequate clearance of certain wire bundles in the ceiling panel near the main passenger door, and corrective actions. This action is necessary to prevent damage to the wires in the bundles due to contact between the bundles and the adjacent ceiling support bracket. Such damage could result in electrical arcing, smoke, or fire in the cabin, and failure of certain systems essential to safe flight and landing of the airplane. This action is intended to address the identified unsafe condition.
