Product Description
The 0177555120 is an overspeed unit that monitors propeller RPM in constant-speed propeller systems. When blade speed exceeds limits, the unit routes pressurized oil to increase pitch angle, automatically reducing RPM to safe operating levels. Mounted on the reduction gearbox as an independent safety limiter, this component protects against overspeed damage during flight operations.
Installation and testing must follow the aircraft or engine maintenance manual and comply with FAA Part 43 standards. Essential for certificated constant-speed propeller installations.
