ABSTRACT:
An aircraft construction having an aircraft engine and an engine nacelle having a wall housing the engine. A cowl door is provided in the wall of the nacelle providing access to the engine to service it. An exhaust duct extends from the engine through the cowl door. The exhaust duct has a first duct section with an outlet end extending from the engine toward the cowl door with its outlet end adjacent the cowl door. The exhaust duct includes a second, separate duct section, having an inlet end, mounted in the cowl door and movable with the cowl door. The inlet end of the second duct section is located adjacent the outlet end of the first duct section, when the cowl door is closed, to have the first and second duct sections together directing exhaust from the engine out of the nacelle. When the cowl door is opened to service the engine, the second duct section moves away with the door making it easier to service the engine.
