The tail gear consists of a wheel assembly, knuckle, treadle, oleo, retraction unit, anti-shimmy brake and wheel lock. Provisions are made for 360¡ rotation of the wheel, and for locking the wheel in a straight fore-and-aft position during takeoff. The tailwheel gear may be retracted either electrically or manually. Electrical retraction is controlled in the cockpit with the same toggle switch that controls the main landing gear retraction motor. For manual retraction, a hand crank is operated through the motor slip clutch.
