Tri-Pacer


Piper had nothing to compete with the Cessna 150, so Piper made use of its Tri-Pac-er tooling and brought forth a two-seat, 108-hp version of the PA-22. A nose-wheel development of the PA-20. This was the final high-wing design to come from Piper. It differed from the PA-20 by having an interconnected aileron and rudder pedal control system,enabling the Tri-Pacer to be flown entirely by the control column without the need to have an input from the rudder pedals during turns. This system was easily disconnected, however, to permit independent use of the ailerons, elevator and rudder. Basically an updated PA-20 Pacer with tricycle undercarriage, the PA-22 Tri-Pacer appeared in 1950 and sold in large numbers.

By 1955 the Tri-Pacer had been updated and fitted with a 150 hp / 112kW Avco Lycoming O-320 engine, as installed in the PA-18 Super Cub. A more powerful version powered by a 160 hp engine was marketed in 1957 and the following year the 150 hp version became the Caribbean. The final PA-22 version was the simplified two-place Colt built from 1960 to 1964. The 125-hp Pacers, fully equipped, sold for $5,170, and the 135-hp models were priced at $6,275, which included an Aeromatic or Sensenich controllable-pitch propeller.

The Colt never had a chance. Despite its eight-horsepower edge over the Cessna 150, it was a stocky, ragwing, flapless loser with a poor glide ratio; slow sales prompted Piper to axe the program after just three years.

The Tri-Pacer Twin had two 100-hp Continentals in its nose, one atop the other, driving a pair of props on concentric shafts. The concept led to a similar sandwich-engine Coman-che study, after Bill Lear assured Piper that the first company to develop a con-ventionally configured "single" with en-gine-out capability would get rich quick. Ed Swearingen, however, who did the feasibility study, convinced Piper that the Comanche would never work.

The PA-22-108, -150, and –16 were certified under FAA 1A6 and by the end of production a total of 9490 had been produced.
