About the Piper 22 Tri-Pacer

The Piper PA-22 Tri-Pacer represents a pivotal moment in general aviation history as the tricycle-gear evolution of the taildragger PA-20 Pacer, making cross-country flying accessible to a generation of post-war pilots intimidated by conventional gear. Introduced in 1950 and produced through 1960, the Tri-Pacer became one of the most successful four-seat trainers and family aircraft of the 1950s, with over 9,000 built. Piper's decision to offer the nosewheel configuration (then still novel for light aircraft) proved prescient, as the forgiving ground handling characteristics opened up flying to thousands of new pilots during aviation's golden age.

The type earned the affectionate nickname "Flying Milk Stool" for its boxy, fabric-covered fuselage and wide-track landing gear, though pilots appreciated the practical design: four real seats, excellent visibility through large windows, and docile flight characteristics that made it ideal for grass strips and short fields. Powered typically by 150 to 160 horsepower Lycoming engines, the Tri-Pacer cruised around 115 knots and could operate comfortably from runways under 1,500 feet. Many examples have been meticulously maintained or restored, and the type remains popular in the vintage aircraft community for its combination of utility, simplicity, and 1950s charm.
