The Cessna 414 is an American light, pressurized, twin-engine transport aircraft built by Cessna. It first flew in 1968 and an improved variant was introduced from 1978 as the 414A Chancellor.
Design and development
The pressurized 414 was developed to appeal to owners of un-pressurized 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 (231 kW) Continental TSIO-520-J horizontally-opposed six cylinder engines. The prototype, registered N7170C, first flew on 1 November 1968 and production aircraft were available in a number of optional seating arrangements and avionics 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.
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.

American gospel singer Keith Green and 11 other people were killed on July 28, 1982 in a Cessna 414 shortly after takeoff at the private Garden Valley Airport, near Garden Valley, Texas. 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.
