Air Tractor AT-402A
Everything here is true of every aircraft of the type, not of any one aircraft.
The AT-402A is the low-cost turbine version of the AT-401B: the long-span (51 ft) 400-gallon airframe with a 550 hp Pratt & Whitney PT6A-20, built by Air Tractor as the entry turbine with 103 completed by the end of 2001. Dimensions are the 400 family's 27 ft length and 8 ft 6 in height.
The PT6A-20 is an old, low-powered PT6 and that is the whole buying question: it is cheaper to acquire than an AT-402B's -15AG and it has less margin on a hot day with a full hopper, while the overhaul and hot-section regime is the same money as any small PT6. Air Tractor's history calls the 402 series the pairing of turbine power with affordability, and the A is the most affordable of them. Weights and performance are blank because neither the TCDS nor a 402A-specific sheet was read; the existing AT-402B row is a sibling with a different engine, not a substitute. No current asking price was found.

| Maintenance reserve | hourly | not counted | |

| Annual inspection | fixed | not counted | |
| Hangar | fixed | not counted |
Not in the totals: Maintenance reserve, Annual inspection, Hangar. We have no reliable default for these lines; enter your figure to include them.
No fuel burn is on record for this model, so fuel is not included.
No TBO or overhaul cost is on record for this model, so the engine reserve is not included.
How these estimates are built. Fuel = this model's typical burn x the national average price from AirNav's Fuel Price Report (100LL $7.41, Jet A $7.66 per gallon, 5 Oct 2026; your airport may differ by $2 or more). Engine reserve = typical overhaul cost / TBO for this engine. The remaining lines are class-level defaults, not quotes for this aircraft: annual inspection is the base inspection fee (findings are counted in the per-hour maintenance line); insurance assumes an instrument-rated owner with time in type and a $1M liability limit - less experienced pilots commonly pay 1.5-2x; hangar and tie-down are national mid-tier figures, with rural and metro options; the rental rate is a 2026 flight-school rate for a comparable aircraft, including fuel. Twin and turboprop maintenance defaults are estimates, not published figures. Sources: AirNav, BWI Aviation Insurance (2019-2026), Flying (May 2026), Savvy Aviation, American Flight Schools, published airport rate sheets. Every default is editable - change any number to match your situation. Depreciation, taxes, financing and major upgrades are not included. Depreciation is not included. An estimate, not a quote.

- Accident record: class median 0 · 16 models in class.
- Severity: class median 20.2.
- Access: class median 5,000.
- Support: class median 48.
- Liquidity: class median 23.47.
- Each of the five categories places the model within its peer class, from 0 (the worst of the class) to 10 (the best): a position among comparable models, not a grade. The overall score is the sum of the categories shown that are scored, out of 10 for each (50 when all five are); it is given only when at least 4 of the five are scored, and it can be set against another model's only when both are in the same peer class and scored on the same categories. When accident record and severity cannot be scored because the model has too few records, the other three give a partial score out of 30, labelled as such; it is never set against a full score.
