Abstract: An accessory mounting assembly for use in a helicopter, the assembly comprising a fitting for attachment to the helicopter in place of or in conjunction with a tail rotor pedal assembly on the flight deck of the helicopter, a post slidably engaged within a large bore in the fitting, and retained in position by a retaining pin. A platform on the second end of the post is used for supporting optional equipment and accessories. Alternatively, additional posts may be interchanged with the post for specialized applications.

Abstract: A ballistic shield (10) for mounting to an aircraft fuselage (14) is formed of lightweight, composite material and shaped to conform to the shape of the fuselage belly that when mounted creates a space (30) between the shield (10) and the belly (14) to enable energy-absorbing deflection of the shield (10). Compartments (36) formed in the shield midsection (24) receive removable inserts (44) that can be constructed of different ballistic-resistant materials to enable field modification of the shield (10) to meet a perceived threat level.

Abstract: The present invention provides a valve for preventing contamination of a fuel management system connected to a pneumatic sense line by closing communication of compressed air from a scroll of the engine through a passageway in the valve to the pneumatic circuitry of the fuel management system. A detent is located on one side of the valve for receiving a raised surface on the knob of the valve and for holding the valve in the open position. A pair of stops on a camming surface separately engage a second pin on the valve to stop a handle of the valve from rotating past the selected open or closed position. The valve has all metal surfaces isolated so it may withstand vibrations. A method of washing a compressor of an aircraft engine is disclosed.
