Cessna 401/402 family

The Cessna 401/402 family, introduced by the American manufacturer Cessna in the early 1970s, represents a versatile line of twin‑engine, piston‑powered light aircraft. Development began in 1970 as a response to the growing demand for reliable commuter and cargo transport in regional markets. The first prototype, the Model 401, flew in 1970 and entered production in 1971, while the larger, higher‑gross‑weight Model 402 followed a year later. Both variants share a low‑wing, all‑metal airframe, fixed tricycle landing gear, and twin Continental IO-520 or IO-550 engines delivering 285 to 310 horsepower each. The 401 is typically configured for eight to ten passengers, whereas the 402 can accommodate up to ten passengers or a comparable cargo load, thanks to its strengthened floor and optional freight door. Notable features include simple, rugged systems, excellent short‑runway performance, and relatively low operating costs, making the aircraft popular with operators such as air taxis, sky‑diving schools, and utility carriers. Over 2,000 units were built, and the type remains in service worldwide, underscoring its lasting impact as a workhorse of general aviation and regional transport. Its enduring reliability continues to influence modern twin‑engine designs and training curricula.
