The pressurized 414 was developed to appeal to owners of unpressurized, twin-engined aircraft, and was based on the fuselage of the Cessna 421 and used the wing design of the Cessna 401. The 414 is a low-wing cantilever monoplane with a conventional tail unit and a retractable tricycle landing gear. It is powered by two wing-mounted 310 hp Continental TSIO-520-J horizontally opposed, six-cylinder engines. The Chancellor has a maximum speed of 270 mph, a climb rate of 1,700 feet per minute, and a ceiling of 30,000 feet with a range 1,528 miles.
