Airworthiness Directive · Amendment 39-11381 · British Aerospace BAe Model ATP Airplanes
British Aerospace BAe Model ATP Airplanes
BAe Model ATP airplanes, except those airplanes on which British Aerospace Modification 10455A or 10455B (reference British Aerospace Service Bulletin ATP-71-15, dated December 11, 1998) has been accomplished, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace BAe Model ATP airplanes, that requires 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 amendment also provides for an optional terminating action for the repetitive inspections. This amendment 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 this AD are intended to prevent chafing within the engine nacelle, which could result in flammable fluid leaking into a zone that contains ignition sources.
