## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain British Aerospace BAe Model ATP airplanes. This proposal would require repetitive inspections to detect chafing on the fuel manifold drain hose and the adjacent access panel; and corrective actions, if necessary; and installation of a protective spiral wrap on the fuel manifold drain hose. This proposal also would provide for an optional terminating action for the repetitive inspections. This proposal is prompted by reports of chafing between the fuel manifold drain hose and the access panel due to contact between the two components over time. The actions specified by the proposed AD are intended to prevent chafing within the engine nacelle, which could result in flammable fluid leaking into a zone that contains ignition sources.
