Location: Bunkie, LA
Accident Number: CEN20CA103
Date & Time: 02/22/2020, 1520 CST
Registration: N602BK
Aircraft: Air Tractor AT 602
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Positioning

The pilot was performing a straight in approach and landing. The airplane touched down on the runway centerline and under control. After the tailwheel settled onto the runway, the pilot applied the brakes and retarded the engine power into the beta range. Shortly afterward, the airplane began to swerve to the left. The pilot's efforts to maintain directional control were unsuccessful and the airplane departed the left side of the runway. The momentum of the airplane resulted in a "classic ground loop" as it encountered the soft ground adjacent to the runway and then contacted a crop of sugarcane. The airplane sustained damage to the fuselage, right wing and vertical stabilizer.

The pilot noted that the "mishap was most likely preventable" because he did not ensure that the tailwheel lock was engaged before landing.
