PIPER U-11 (UO-1) PA-23-250 AZTEC
Title: Piper U-11 Aztec (UO-1) PA-23-250
The first PA-23 was developed by Piper from a design inherited from the Stinson aircraft company and first flew in 1952. This aircraft was not successful and was re-developed as the PA-23 Apache with more powerful engines and a re-designed tail. In 1959 the design was further re-developed with more powerful engines and a swept fin, and re-named the Aztec.
The aircraft remained in production until 1982 by which time nearly 7,000 examples of all models had been produced. 20 PA-23-250 Aztecs were purchased by the US Navy for liaison and flight proficiency purposes, later re-designated U-11. They were retired in the mid 1970’s.
