AT-402A & AT-402B

Air Tractor | November 13, 2010

Air Tractor Inc have been manufacturing aircrafts from such as the Air Tractor AT-400 from 1979. This was based on a family of the first agricultural air crafts built in the USA. The Air Tractor AT-400 is a monoplane taildragger with a low wing. Between its engine and cockpit, it carries a chemical hopper and hence it derived the name as monoplane taildragger. It had various versions based on the same platform. Those were the AT-400, AT-400A, AT-401, AT-401A, AT-401B, AT-402, AT-402A and AT-402B. The AT-402A and AT-402B are twin seater planes low cost turbine planes which are ideal for first time buyers of turbine small planes.

The differentiation between the two AT-402A and AT-402B models from Air Tractor Inc is that the latter has a more powerful 680shp PT6A-15AG engine. This makes the Air Tractor a hoot to fly as well as it can carry around heavier loads. The other significant difference is that in the AT-402B model, you can find a feature named as amphibious airbladder. This assists the plane while landing on water as well as terra firma. Many of the first time buyers would be glad to know that this airplanes have simple and easy to understand instruments, the best reliable engine in the market as well as that its service schedule is far more spread than others in its class. It also carries the latest technological and safety features which though not visible, help the pilot in flying with ease and peace of mind.


A new AT-402A or for that matter AT-402B are both available at a highish price than their competitors however a used or second hand plane would be available a bit cheap than what you can expect. The problem lies in the fact that there wouldn’t be too many around in the second hand market as buyers find it hard to part with these specimens. They are acclaimed for their fuel efficiency as well as reliability quotient.
