The Cessna Model 411 is a 1960s American twin-engined, propeller driven light aircraft built by Cessna Aircraft. It was that company's largest business aircraft when it first flew in 1962, other than a four-engined airliner developed during the 1950s, which was not put into development.
Design and development
The Cessna 411 was a new design that started life as the Cessna 410 concept (of which none were actually built). It has 340 hp (254 kW) Continental Motors GTSIO-520-C engines. It had a crew of one or two and room for four to six passengers. The prototype first flew on 18 July 1962. During 1965 Cessna developed two generally similar and lower-cost versions, the Model 401 and Model 402. Production of the 411 finished in 1968. A pressurised version of the 411 was developed as the Cessna 421. The 411 has been subject to rigorous re-testing of its flight performance in the 1990s by Cessna and the Federal Aviation Administration due to a number of accidents. This testing confirmed that the aircraft meets all the design requirements for certification. Today, vortex generators are able to be fitted the aircraft, which make single engine handling easier.
- Cessna 411 - Production version, 250 built.
- Cessna 411A - 411 with larger nose baggage capacity but the same overall length fuselage and optional tanks in engine nacelles, 50 built. The Cessna 411A had 200 improvements over the Cessna 411 and is much more sought after in the market. This is evidenced by the resale value in excess of $200,000 vs the 411 at about $50,000.
