Product Description
The 66503 is an electromechanical synchronizer actuator for propeller control systems. It converts electrical inputs into controlled linear motion to maintain propeller RPM and phase synchronization across multiple engines. This actuator integrates within the synchrophaser valve assembly, actuating the propeller governor to coordinate blade pitch and engine speed.
Found on twin-engine and multi-engine aircraft, it ensures synchronized operation during flight. Installation follows the aircraft maintenance manual with verification against the Illustrated Parts Catalog for proper fit and interface compatibility.
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.
Frequently Asked Questions
