PROP PROTRACTOR (P/N 33-ks) - As Removed, Serviceable

The 33-ks prop protractor measures and sets propeller blade pitch angle in degrees during ground maintenance. This tool verifies equal geometric pitch across all blades on controllable-pitch or ground-adjustable propellers, ensuring balanced blade positioning that reduces vibration and improves flight characteristics. Mechanics use the protractor's degree-scale reference to match blade angles precisely during propeller service and adjustment.

Follow propeller manufacturer specifications and FAA AC 43.13-1B guidance when setting pitch to maintain airworthiness compliance.
