Development

When Piper dropped the J- designation system in exchange for the PA- system, the J-5C became the PA-12 "Super Cruiser". The earlier J-5s had been powered by either a 100 hp (75 kW) Lycoming O-235 or a 75 hp (56 kW) Lycoming O-145. The newer PA-12 model was initially powered by a 108 hp (81 kW) Lycoming O-235-C engine, was fully cowled, and had a metal spar wing with two 19 gallon fuel tanks. A Lycoming O-235-C1 engine rated at 115 hp (86 kW) for take-off was optional.

The PA-12 is approved for wheels, skis, floats and also for crop spraying.

Cockpit accommodation is provided for the pilot in the front seat and two passengers in the rear seat, side-by-side. Unlike the J-3 Cub the PA-12 is flown solo from the front seat.

Operational use

Many PA-12s have been modified with larger engines. Wing flaps and a metal-skin fuselage can be added as modifications.

In 1947, two PA-12s flew around the world, and the worst mechanical failure they suffered was a cracked tailwheel.

Many PA-12s are still flown and the type is commonly seen in North America. In November 2009 there were still 1688 registered in the USA and 229 in Canada.
