|A Cessna 414 Chancellor at Amsterdam-Schiphol Airport, 1990|
|Role||Six/eight-seat light transport|
|National origin||United States|
Design and development
The pressurized 414 was developed to appeal to owners of un-pressurised 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 310hp (231kW) Continental TSIO-520-J horizontally opposed-six piston engines. The prototype, registered N7170C, first flew on 1 November 1968 and production aircraft were available in a number of optional seating arrangements and avionic packages. The name Chancellor was used for models marketed from 1976. An improved variant the Cessna 414A Chancellor was introduced in 1978 with the major change being a re-designed and increased-span wing with integral fuel tanks and an extended nose to give more baggage space.
In 1974, American Jet Industries built a turboprop-powered conversion of the Cessna 414, named the Turbo Star Pressurized 414, using Allison 250-B17B engines. Scenic Airlines of Las Vegas purchased the rights to the design in 1977.
Thielert has offered engine conversions using their Centurion Engine. This involves the installation of FADEC-controlled aviation diesel piston engines that run on commonly available jet fuel. Thielert claims increased power and improved fuel economy over other available conventional piston engines.

Accidents and incidents
- American gospel singer Keith Green and 11 other people were killed on July 28 1982 in a Cessna 414 shortly after takeoff at Garden Valley Airport. The NTSB report indicates that the probable cause of the crash was a combination of the aircraft being overloaded (the occupants were 4 adults and 8 children, while the aircraft has only seven seats) and pilot's failure to calculate weight and balance relative to the aircraft's design parameters.
- American actor Patrick Swayze was involved in an incident in which a Cessna 414 he flew experienced a sudden decompression at 12,900 feet over Arizona. Swayze circled, descended and maneuvered the plane to a rough landing at a housing development under construction, missing a truck by 5 feet and losing much of the right wing due to striking objects on rollout. The NTSB report indicates that the probable causes were the failure of a pressurization duct at altitude (resulting in a loss of cabin pressurization and subsequent mild hypoxia), and carbon monoxide (from both a malfunctioning cabin heater and use of tobacco products in flight). The incident became the subject of much tabloid sensationalism, speculating alcohol abuse during flight and a cover-up attempt by Swayze. An investigation of the incident exonerated Swayze of these suspicions.
