Incident Overview
A pilot engaged in aerial application operations experienced a loss of directional control during takeoff from a private airstrip after completing the day's spraying activities. The takeoff was initiated to the north while an approaching thunderstorm cell and heavy rain were present in the area.
Weather Conditions
During the takeoff roll, winds in the vicinity shifted to southwesterly at approximately 20 knots, gusting to 25 knots. A nearby weather observation station recorded a significant wind shift: at 1800, winds were from the north-northwest at 10 knots; by 1900, they had shifted to southwesterly at 27 knots with gusts to 32 knots.
Sequence of Events
As the aircraft accelerated, the pilot was unable to maintain directional control. The aircraft ground-looped, causing the right main landing gear to collapse and the right wing to sustain damage. The pilot reported that no mechanical failure or malfunction contributed to the occurrence.
Post-Incident Observations
No injuries were reported. The aircraft sustained structural damage to the right main gear and wing. The pilot's account indicated that the event was solely related to the wind conditions encountered during the takeoff.
