Piper U-11A
Piper U-11A Aztec
The Piper PA-23 was one of the first twin-engine light aircraft available in the United States. It was introduced in 1954 as the four-seat Apache. The popularity of the design led Piper to develop the larger six-seat Aztec that also incorporated more powerful engines. In 1960, the U.S. Navy purchased twenty Aztecs for use as short-range transports designating them UO-1. They were also used to allow Navy pilots who had been assigned non-flying duties to maintain their skills and flight pay. The designation was changed in 1962 to U-11. The Aztecs remained in Navy service until the mid-1970s.
