70101-31000-043 Primary Main Rotor Pitch Link – Sikorsky H?60/S?70 Control Rod Assembly

Description

The 70101-31000-043 Main Rotor Pitch Link is a precision?engineered flight?control linkage used on Sikorsky H?60 and S?70 series helicopters. Classified as a critical rotor?control component, this pitch link transfers pilot inputs from the swashplate to the main rotor blade pitch horns, enabling accurate pitch adjustments and stable aerodynamic performance. Manufactured from high?strength alloys with corrosion?resistant rod ends and 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 preload, alignment, and smooth control response throughout the aircraft’s flight envelope.
