The Cessna 401 and 402 are series of 6 to 10 place, light twin, piston engine aircraft. This line was manufactured by Cessna from 1966 to 1985 under the name Utiliner and Businessliner. All seats are easily removable so that the aircraft can be used in an all-cargo configuration. The Cessna 401s, 402s, 402As and some 402Bs built from 1966 to 1971 had four small oval windows which gave them a similar appearance as pressurized jets because only very few passengers could fit into these planes with limited legroom for any one passenger’s knees or feet touching another seatmate except on front row if there is no room behind it for larger personnel like pilots or flight attendants
