Product Description
The 66634-004 is an aircraft propeller governor that regulates engine RPM by modulating oil pressure to the constant-speed propeller. During flight, this governor maintains the pilot's selected RPM setting automatically, adjusting blade pitch as power and airspeed change. Commonly installed on Piper PA-28R-201 and similar aircraft with constant-speed propellers, the governor interfaces with engine oil pressure lines and propeller control linkages.
Installation and rigging must follow the aircraft maintenance manual specifications. Verify compatibility through your Illustrated Parts Catalog before installation.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
