Probable cause

The failure of the pilot to compensate for the unfavorable wind conditions.

Analysis

The pilot had been conducting swath runs in an agricultural spray operation. He was making a procedure turn-around to finish up the field with the remaining chemical. About half-way thru the turn the pilot reportedly encountered unfavorable wind conditions which resulted in a loss of altitude and impact with rising terrain. The pilot reported changing winds and downdrafts in the area during the swath runs. Offical wx records were not available to confirm the wind conditions. No mechanical deficiency was noted with the airplane during post accident exam.
