Narrative:
On July 27, 2023, at 1430 central daylight time, an Air Tractor Inc. AT-802A airplane, N8503W, was substantially damaged when it was involved in an accident near Aberdeen, South Dakota. The commercial pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 137 aerial application flight.

During the taxi with a 12 kt left quartering crosswind, the pilot applied right brake to turn toward the taxiway C2, the airplane did not respond, and started to turn to the left. The pilot reported that he applied full braking action but was unable to arrest the turn. The airplane departed the left side of the taxiway and came to rest on a 240° heading, with the right main landing gear folded beneath the fuselage. Photographs of the accident site depicted dark, arcing tire marks on the taxiway surface that continued into the grass and ended at the left main landing gear. Tire marks aligned with the right main landing gear began on the taxiway surface, continued into the grass and terminated at the right main landing gear. The airplane sustained substantial damage to the right wing and the main landing gear mount structure.

The right main landing gear attachment hardware was retained and forwarded to the National Transportation Safety Board Materials Laboratory in Washington, DC, for examination. The hardware was examined using a bench binocular microscope and a hardness tester. Examination of the hardware revealed the fracture faces exhibited fracture features typical of overstress separation, with no evidence of fatigue cracking present.
