Cessna 421 C Exhaust Parts

         The Cessna 421 Golden Eagle is a light transport, twin engine, 7-seat aircraft produced by Cessna in the 1960 s that was originally designed as a pressurized version of the of the Cessna 411. As the largest and fastest twin-engine piston aircraft by Cessna, the 421 was designed with a sleek, all-metal low-wing cabin, with a retractable tricycle landing gear, while being powered by two Continental GTSIO-520-D engines.

            As one of the variants of the original 421, Cessna first released the Golden Eagle/Executive Commuter 421C in 1976, which features new wing and landing gear and comfortably seats six passengers in addition to a one-two person crew and is powered by two Continental GTSIO-520-Ls or Continental GTSIO-520-Ns, with 375  hp per engine. Additional changes from the original 421 include, the absence of wingtip fuel tanks and changing of the landing gear from straight-leg to a trailing-link design beginning from 1981-1985. Production of the 421C ended in 1985 after a total of 1,901 aircraft had been made.
