The Piper PA-31 Navajo series was designed to bridge the gap between light twins and larger cabin-class aircraft, offering operators a capable, comfortable platform for business and regional use. Powered by twin turbocharged Lycoming engines, the Navajo cruises around 220 knots with a range of roughly 1,000 nautical miles and seating for six to eight passengers. Its pressurized variants, such as the Chieftain and Mojave, brought higher altitude capability and improved passenger comfort, while maintaining the simplicity and serviceability that made Piper famous.
Throughout its production, the PA-31 family proved versatile—serving roles from executive transport to cargo hauler—with variants tailored to both private owners and commercial operators. Its durable airframe, ample cabin, and straightforward systems have earned it a lasting reputation as a dependable workhorse in the cabin-class twin market.
The original model, powered by twin turbocharged Lycoming engines producing 310 hp each. It established the platform’s reputation for reliable, comfortable regional travel with a spacious unpressurized cabin and balanced performance.
Added cabin pressurization and 425 hp engines, allowing higher cruise altitudes and smoother operations above weather. The pressurized design enhanced passenger comfort and operational flexibility for longer, higher-altitude missions.
Featured counter-rotating engines to eliminate critical engine handling issues, while improving safety and controllability in single-engine situations. It also offered increased gross weight and refinements to systems and cabin layout.
The most popular variant, stretched for greater passenger capacity (up to 10 seats) and fitted with 350 hp engines. Its improved payload and pressurized comfort made it a regional airline and charter favorite for decades.
A turboprop evolution of the PA-31 airframe, featuring Pratt & Whitney PT6A engines and significant aerodynamic and structural upgrades. The Cheyenne delivered jet-like performance, higher speeds, and modern avionics, positioning it as a true step-up aircraft for commercial and corporate operators.
The final piston development, combining Chieftain wings and structure with pressurization and 350 hp engines. It offered improved efficiency, comfort, and range, appealing to private and business operators seeking the most refined piston Navajo experience.
