Spot it by:

Closely resembles the AT-402 but is visibly longer ahead of the cockpit due to the stretched hopper; the PT6A cowling is the same but the fuselage has a more pronounced hump forward. All Air Tractor models share the characteristic low-wing, aft-cockpit layout with spray booms under the wing.

History

Introduced in 1987, the AT-502 was designed to increase payload and productivity over the earlier AT-400 series. The Pratt & Whitney Canada PT6A-34AG turboprop gave ample power to lift full hoppers from short, unimproved runways typical of agricultural strips. It rapidly became Air Tractor's most popular model.

Variants

The AT-502A and AT-502B offer progressive refinements; the AT-502B features an 18-inch forward fuselage stretch for additional hopper volume. A floatplane version is also produced for fire-fighting support.

Where you'll see it

The AT-502 series accounts for a substantial share of the turbine agricultural aircraft fleet in North America, Australia, New Zealand, and South America; many operators run mixed fleets pairing AT-402s and AT-502s.
