Piper Tri-Pacer


The first Piper Tri-Pacer was the PA-22 model. Piper manufactured 7,668 of these airplanes from 1952 through 1960. The name Tri-Pacer is based on its tricycle landing gear configuration, though a number of owners have converted the plane to a taildragger, with the third wheel being located beneath the tail.

One of the unique features of the Tri-Pacer is the light spring load installed between the rudder and the aileron. It was intended to counteract the adverse yaw that planes naturally experience when turning.

Not everyone liked this feature however, and it was removed from many planes, especially those that were converted to a taildragger. Another unusual feature of the Tri-Pacer is the braking system. A lever that many pilots call a “Johnson Bar” hangs down from beneath the control panel. It activates both brakes simultaneously. As with some of the other features, the Johnson Bar has been converted to standard individual toe brakes on many Tri-Pacers.

The true test of a pilot’s knowledge regarding the Piper Tri-Pacer is if he or she knows how to start the plane. Except for those airplanes that have been converted to a standard starting system, Tri-Pacers have the starter button and master switch located underneath the pilot’s seat instead of on the control panel.

Because of the Tri-Pacer’s short wingspan, it doesn’t glide like a Cessna 172. Some complain that the airplane practically falls to the ground when the engine is off or at idle because it glides faster and steeper than its rival aircraft.
