The Cessna 340 is a fixed-wing, American-designed light twin aircraft configured for personal and small-charter travel. It features a pressurized cabin with six seats and twin engines, serving private operators who require high-altitude capabilities and comfortable passenger transport. Its layout includes retractable landing gear and an airstair door.
Developed as a cabin-class development of the unpressurized Cessna 310, the aircraft shares structural elements such as wings and flaps with the larger 400 series. It is powered by turbocharged Continental engines equipped with safety stops to prevent overboosting. Production took place during the nineteen-seventies and nineteen-eighties, establishing it as an entry-level pressurised twin in general aviation.
