NTSB Factual Report

During the takeoff roll, the agricultural category airplane encountered a rough patch on the runway surface of the agricultural airstrip. The pilot then lost control of the airplane, which ground looped, departed the runway, and came to rest in an adjacent canal. The airplane sustained substantial damage to the right wing spar during the accident sequence. There was no report of a mechanical failure or malfunction.

NTSB Probable Cause

The pilot's failure to maintain directional control during the takeoff roll on a rough runway surface.
