BELL CRANK (P/N 446-402) - New Surplus

The 446-402 is a bell crank used in aircraft flight-control linkages to redirect cable and pushrod motion. This mechanical component converts cable movement into perpendicular pushrod travel, enabling efficient control transmission between cockpit inputs and control surfaces like ailerons. Typically installed in wing structures between control cables and aileron pushrods.

The bell crank pivots on a central pin, allowing bidirectional motion transfer while maintaining precise rigging geometry. Installation and rigging should follow AC 43.13-1B control-cable practices. Verify applicability in your aircraft's Illustrated Parts Catalog before installation.
