The Cessna 401 and 402 are a series of 6 to 10 seat, light twin-piston engine aircraft. All seats are easily removable so that the aircraft can be used in an all-cargo configuration. Neither the Cessna 401 nor the 402 were pressurized, nor were they particularly fast for the installed power. Instead, Cessna intended them to be inexpensive to purchase and operate.

The Cessna 414 is an American light, pressurized, twin-engine transport aircraft built by Cessna. It first flew in 1968 and an improved variant was introduced from 1978 as the 414A Chancellor.
