What happened
The aircraft sustained damage after it nosed over into a ditch while landing on a gravel road. This incident occurred immediately following the completion of an aerial application flight. During the landing rollout phase, the pilot lost directional control of the airplane. As a result, one of the main landing gear struts veered off the paved surface and entered a drainage ditch.
The force of the impact caused the aircraft to pitch forward violently. The plane then flipped over and came to rest in an inverted position on its back. Despite the significant damage to the airframe, the pilot was able to extricate themselves from the wreckage.
The investigation
Post-accident examination confirmed that the primary cause of the nose-over was the loss of directional control during the final phase of the landing. The structural failure began when the main gear encountered the ditch on the side of the gravel road. This event triggered the subsequent nosing over and inversion of the aircraft.
Findings
The pilot reported that environmental conditions played a significant role in the accident. Throughout the day, winds were noted to be shifting direction and changing velocity frequently. These unpredictable wind conditions likely contributed to the difficulty in maintaining proper alignment and control during the landing rollout on the narrow gravel surface.
