Design and development
The pressurised 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 was a low-wing cantilever monoplane with a conventional tail unit and a retractable tricycyle landing gear. It was powered by two wing mounted 310hp (231kW) Continental TSIO-520-J flat-six piston engines. The prototype, registered N7170C, first flew on the 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.
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 (Occupants were 4 adults and 8 children, while the aircraft has only seven seats) and pilot inexperience.
