Incident Overview
According to the pilot's account, the flight departed from Pineland carrying a load of chemicals. The pilot was unable to locate the assigned field and subsequently returned to the airport with the full load intact. The landing was conducted on runway 35.
Landing and Mechanical Issue
During the landing roll, the pilot attempted to decelerate the aircraft by engaging Beta mode. However, the right brake failed to operate as expected. The pilot reported that the resulting engine torque then pulled the aircraft to the left, initiating a ground loop.
Damage Sustained
As the ground loop occurred, the right main landing gear collapsed and folded under the fuselage. Additionally, the right wing sustained structural damage, bending at the midpoint.
Pilot Statement
The pilot's description of the event indicates that the right brake failure and subsequent asymmetric thrust from the engine torque were the immediate causes of the loss of directional control, leading to the ground loop and consequent damage.
Investigation Findings
The investigation relied solely on the pilot's report. No further determination of causal factors or contributing elements was provided. The aircraft's specific type, registration, operator, and other operational details were not disclosed in the available information.
