Cessna 310

The Cessna 310 is an American four-to-six-seat, low-wing, twin-engine piston monoplane that Cessna built from 1954 to 1980, the second twin the company put into production after the T-50. It first flew on 3 January 1953 and deliveries began in late 1954. Early aircraft stored all fuel in tip tanks and used exhaust thrust augmenter tubes, which were replaced in 1964 by exhaust routed under the wing, and the 310G of 1961 introduced the canted wingtip tanks that became common across Cessna twins. The turbocharged 320 Skyknight was developed from the 310F, and the United States military used the type as the L-27, redesignated U-3 after 1962. More than six thousand 310 and 320 aircraft were produced in total.
