Air Tractor AT-602

Overview

The Air Tractor AT-602 was introduced in 1995 to bridge the gap between the mid-sized 500-series and the heavy-lift 802-series. Featuring a massive 630-gallon hopper and a 1,050 SHP Pratt & Whitney PT6A-60AG engine, the AT-602 is a high-productivity machine designed to cover over 1,000 acres in a single morning. Despite its large size and 12,500 lb gross weight, pilots frequently praise the 602 for its surprisingly light and responsive control feel, aided by aileron boost tabs and a well-balanced airframe.

Key Features for GA Buyers/Operators

• High Productivity: The 630-gallon hopper capacity significantly reduces ferry time and loading cycles compared to smaller ag-planes.
• Modern Powerplant: The PT6A-60AG provides massive flat-rated power, ensuring reliable performance in high-density altitude environments.
• Cockpit Comfort: Features a wider, more spacious cockpit than earlier models, with improved environmental controls and ergonomic control placement for long working days.
• Quiet Operation: Often equipped with a 5-blade Hartzell propeller, which reduces noise signatures—a critical factor for work near residential areas.

Trade-offs

• Large Footprint: With a 56-foot wingspan, the AT-602 requires significant hangar space and is less maneuverable on the ground than smaller tractors.
• Weight Category: At 12,500 lbs MTOW, this aircraft sits at the upper limit of the “Light” aircraft category, requiring experienced pilots familiar with heavy taildragger operations.
• Restricted Utility: Like its siblings, it is a single-purpose tool certified in the Restricted Category, limiting it strictly to agricultural, firefighting, or conservation missions.
