Cessna 310K

First introduced in 1954, the Cessna Model 310 series marked Cessna’s entry into the twin‑engine civil market. The 310K, produced from 1962 to 1967, represented the penultimate evolution before the 310R. It incorporated a strengthened airframe, redesigned wings with a 40‑inch longer span, and more powerful Continental IO‑470‑D engines delivering 225 hp each, raising cruising speed to roughly 190 knots. The fuselage retained the characteristic low‑wing, all‑metal construction but featured a larger windshield and refined interior accommodations for up to six passengers. Fuel capacity increased to 124 gallons, extending range beyond 1,200 nautical miles, while the upgraded landing gear offered improved ground handling on unimproved strips. The 310K’s avionics suite included VOR/ILS navigation and optional autopilot, making it popular with corporate operators, air charter services, and flight schools seeking twin‑engine proficiency. Its reliability, relatively low operating costs, and respectable performance cemented the 310K’s role as a bridge between modest single‑engine pistons and larger pressurized twins, influencing subsequent Cessna designs and contributing to the growth of general aviation twin‑engine fleets worldwide. Today many well‑maintained 310Ks remain active, serving as a reliable platform for aerial photography, survey work, and nostalgic recreational flying.
