About the PIPER PA-31-350
The Piper PA-31-350, also known as the Navajo Chieftain, is a prominent general aviation aircraft developed by Piper Aircraft in the late 1960s. The Navajo Chieftain was introduced to meet the growing demand for a larger, more powerful aircraft capable of carrying more passengers and cargo over longer distances. It is an extension of the PA-31 Navajo series, which was designed as a twin-engine light transport and executive aircraft. The PA-31 series was targeted primarily at the business and commuter airliner market, a niche that was expanding rapidly during this period.
The PA-31-350 Navajo Chieftain was first produced in 1973. It was developed based on the original Navajo airframe but incorporated several key improvements. The most significant enhancement was the upgrading of engines to two Lycoming TIO-540-J2BD turbocharged engines, each producing 350 horsepower, thus giving the Chieftain better performance, particularly at higher altitudes, and superior speed and range compared to its predecessors. Another critical feature was the increase in cabin length, allowing the aircraft to accommodate up to ten passengers, with a variety of seating and cargo arrangements, thus making it very versatile.
Key Features and Capabilities
Piper continued to produce the PA-31-350 until 1984, cementing its legacy as a reliable workhorse for small airlines, charter services, and corporate owners. During its production run, the Chieftain earned a reputation for its solid construction, ease of handling, and ability to operate from short and unpaved runways—an advantage for operations in remote or less-developed regions.
The PA-31-350 played a significant role in connecting smaller communities and providing an affordable, efficient means of transportation for various needs. Its adaptability in different roles—such as air ambulance, cargo transport, and even some military applications—further showcased its versatility. The Navajo Chieftain remains a respected and admired aircraft in the history of general aviation for its contribution to regional air travel and its operational robustness.
