NTSB Factual Report

The pilot reported that during the takeoff roll, the airplane drifted left of the runway center and the left main landing gear struck an unknown object in the tall grass. The pilot stated that he was unsure of the damage and continued his aerial application flight.

During landing, observers on the ground determined that the left main landing gear was damaged. The pilot diverted to an airport that he determined would be more suitable for an emergency landing. During the landing, the left main landing gear collapsed, which caused substantial damage to the left wing.

The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to maintain directional control during the takeoff roll, which resulted in the airplane's left main landing gear impacting an unknown object, and subsequent collapse during landing.
