Product Description
The c-5291 is a dense metal counterweight for McCauley constant-speed propellers. Installed at the hub or blade root, it provides centrifugal balancing force that biases blades toward commanded pitch angles during flight. The counterweight maintains blade synchronization and reduces vibration in the propeller assembly.
Installation and balancing must follow the propeller maintenance manual and FAA AC 43.13-1B guidance. Proper counterweight function is critical for smooth operation and pitch control in constant-speed propeller systems.
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.
