The Cessna 150 is a two-seat tricycle gear general aviation airplane that was designed for flight training, touring and personal use.
The resulting 142 was based on the 140, but had tricycle landing gear, which gives the aircraft more docile ground handling than the tailwheel landing gear of the 140; Cessna also replaced the rounded tips of the wings and empennage with more modern-looking, squared-off tips, and the narrow, hinged wing flaps of the 140 were replaced by larger, far more effective Fowler flaps.
[4][5] The Cessna 142 prototype first flew on September 12, 1957, shortly before the aircraft was renamed to Model 150 in October.
With the 1967 Model 150G, the doors were bowed outwards 1.5 inches (38 mm) on each side to provide more cabin elbow room.
The 152 is more economical to operate due to the increased TBO (time between overhaul) of the Lycoming O-235 engine.
This was the first year the aircraft featured a swept tail fin, increased baggage area and electrically operated flaps.
