Piper J-5

Throughout World War II, Piper modified the basic structure of the J-5A. The J-5B had a 75 h.p. Lycoming GO-145-C2 engine. The later J-5C also built as the HE-1 (later AE-1) ambulance for the U.S. Navy with rear hinged fuselage decking, used the fully cowled 100 h.p. Lycoming Military O-235-2 or Civilian O-235-B engine with an electrical system, and redesigned landing gear. After the war, Piper dropped the J- designation system in exchange for the PA- system, and the J-5C became the PA-12 "Super Cruiser". The Super Cruiser was more popular than the basic J-5A, with 3,759 being built. Piper also produced a four-seat variant of the Super Cruiser with a 115-hp engine. It was designated the PA-14 Family Cruiser. It was the least successful of the three Cruiser designs in terms of aircraft sold, with 238 being built in 1948/49, and only about one hundred remain in existence. ==Variants==
