Analysis

The airplane sustained substantial damage when it impacted the ground while spraying a field of corn. The pilot reported, "Upon arrival at the field, it became evident my spray pump was inoperative. My attention was diverted for a moment as I was trying to solve the problem, and my wheels got in the crop. I was unable to recover. The terrain was a flat cornfield and the wreckage was all intact in one spot."
