Product Description

The 25nf-z4057 is a rudder bias panel that mounts on the aircraft instrument panel to house the rudder bias system's enable/disable switch. This control interface allows pilots to engage assisted rudder input, which counters yaw effects during one-engine-inoperative conditions on twin-engine piston aircraft. The panel provides the cockpit-mounted switching capability for the rudder boost system.

Installation requires wiring per the applicable maintenance manual or STC instructions and verification against the aircraft's Illustrated Parts Catalog for 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.
