1976 Piper Navajo PA-31-325 used

The Piper PA-31 Navajo is a family of cabin-class, twin-engined aircraft designed and built by Piper Aircraft for the general aviation market, most using Lycoming engines. It was also licence-built in a number of Latin American countries. Targeted at small-scale cargo and feeder liner operations and the corporate market, the aircraft was a success. It continues to prove a popular choice, but due to greatly decreased demand across the general aviation sector in the 1980s, production of the PA-31 ceased in 1984.

The first PA-31 was flown on July 31, 1967, and it was certified by the Federal Aviation Administration (FAA) in November of the same year. The basic design remained unchanged through the 1975 model year, after which the PA-31-325 Chieftain was introduced. This variant featured an uprated 325 hp (242 kW) Lycoming TIO-540-A2C engine, increased takeoff weight, and improved performance. Other improvements included increased cabin soundproofing and higher fuel capacity.

The PA-31-325 was in production until 1984, when Piper ended production of the Navajo due to decreasing demand for piston-powered aircraft. A total of 1,942 PA-31s had been produced by the time production ended. The Navajo has since become a popular choice for corporate and private transportation, as well as charter and air taxi operations.
