70107-08400-046 Tail Rotor Control Rod Assembly – OEM Anti?Torque Linkage for Sikorsky H?60/S?70 Helicopters

Description

The 70107-08400-046 Tail Rotor Control Rod Assembly is a precision?engineered flight?control linkage used on Sikorsky H?60 and S?70 series helicopters. This assembly transmits mechanical inputs from the tail rotor servo to the pitch change mechanism, enabling accurate adjustment of tail rotor blade pitch for yaw authority and anti?torque stabilization. Constructed from high?strength alloys with corrosion?resistant rod ends and spherical bearings, it is designed to withstand continuous cyclic loading, vibration, and tensile forces encountered during demanding helicopter operations. The assembly incorporates adjustable end fittings to ensure proper alignment, preload, and smooth control response throughout the aircraft’s flight envelope.
