Abstract: A tail rotor assembly includes a slotted pitch horn which replaces a production non-replaceable pitch horn. A slot is cut along a leading edge of each pitch control horn and a chordwise cut is made through the upper and lower blade surface skins. The production pitch control horn is removed from the tail rotor assembly by passing the spar through the slot. The slotted pitch horn is assembled over the spar and a collar is located adjacent thereto. The collar is bonded to the slotted pitch horn and the upper and lower blade surface skins at predetermined bond areas. An inner horn plate and an outer horn plate are bonded over the horn slot and a trailing edge doubler is bonded to the blade trailing edge to finish the trailing edge horn area and close the upper and lower skin surfaces.

Abstract: A valve includes a molded plastic body portion having an internal chamber with upper and lower portions. Fittings connect the valve to conduits of a piping system. A valve seat surrounds inlet and outlet openings in the chamber lower portion. A plastic plug member is rotatably positioned in the valve seat. The plug member is a molded unitary element. The valve body portion and plug member have a substantially uniform wall thickness throughout. The plug member includes an integral plug portion and an actuator portion which facilitates ease of disassembly of the valve for repair. The plug portion has a flow passage which communicates with the inlet and outlet openings in the valve seat and is rotatable between open and closed valve positions. Seals retained on the plug portion engage the valve seat in the closed position. The actuator portion includes shearable stops which permit 360.degree. rotational operation of the plug member upon failure of the stops under excessive torque.
