The Cessna 421 Golden Eagle is an American six or seven seat Twin-engine light transport aircraft, developed in the 1960s by Cessna as a pressurized version of the earlier Cessna 411.
The Cessna 421 was first produced in May 1967. The Cessna 421A appeared in 1968 and the aircraft was redesigned in 1970 and marketed as the Cessna 421B. In 1975 the Cessna 421C appeared which featured wet wings, the absence of wingtip fuel tanks and landing gear that was changed from straight-leg to a trailing-link design from the 1981 model year onwards. Production ended in 1985 after 1,901 aircraft had been delivered.
The Cessna 421 was first certified on 1 May 1967 and shares a common type certificate with Cessna models 401, 402 411, 414 and 425.
Some Cessna 421s have been modified to accept turboprop engines, making them very similar to the Cessna 425, which itself is a turboprop development of the Cessna 421.
The Cessna 421 is an all-metal low-wing cabin monoplane with a retractable tricycle landing gear, and powered by two geared Continental GTSIO-520-D engines, wing-mounted in tractor configuration. The cabin is accessed from a door, on the left hand side behind the wing, and has seating for six on the basic Cessna 421, or up to ten on later variants.
