Cessna 421 for Sale

The Cessna 421, introduced in 1968, targeted buyers seeking enhanced carrying capacity and performance without the high costs of turboprops. Powered by Continental GTSIO-520 geared engines producing 375 horsepower each, the aircraft faced challenges due to high stress, resulting in a short service life with an original TBO of 1,200 hours, later extended to 1,600 hours. While costly to overhaul at an estimated $31,000 per engine, it was comparatively less than its competitors.

The initial model shared features with smaller 400-series Cessna twins, featuring Stabila-Tip fuel tanks, a 170-gallon fuel system, and electromechanical landing gear. With a maximum gross weight of 6,800 pounds, it had a standard fuel system range of 800 miles, extendable to nearly 1,200 miles with an optional 255-gallon system. The 421's success was evident with 200 units sold in its first year.

In 1976, the 421C incorporated sweeping design changes, replacing Stabila-Tip tanks with a bonded wet-wing fuel system, increasing the standard fuel capacity to 213 gallons. This design change enhanced stability, handling, and single-engine performance. The hydraulic landing gear replaced the electromechanical system, improving reliability. The C model had a maximum gross weight of 7450 pounds, similar to the B, but with a higher standard empty weight.
