Product Description

The 177555120 is an overspeed unit that protects propeller systems from excessive RPM. This speed-sensing safety device detects overspeed conditions and modulates oil flow to the propeller governor, limiting rotor speed within safe operating parameters. Installed within propeller control assemblies on aircraft with constant-speed propellers, the unit prevents mechanical damage from over-rotation during flight operations.

Installation and rigging must follow the aircraft maintenance manual and verified against the Illustrated Parts Catalog for your specific airframe.
