Analysis

The pilot said that he 'forced' the turn when trying to line up for an aerial application swatch run. He said that the airplane stalled, he recovered once, but stalled a second time when he attempted to lift the nose to avoid impact with the terrain, The pilot did not indicate any mechanical anomalies in the operation of the airplane.

Factual narrative

On June 26, 1998, at 0955 central daylight time, a Rockwell International S2-R, N5682X, encountered a loss of control and impacted the terrain while maneuvering at a low altitude near Williams, Minnesota. The commercial pilot received no injuries and the airplane sustained substantial damage. The airplane was being operated as a commercial flight under 14 CFR Part 137 and performing aerial applications when the accident occurred. The flight originated from Williams, Minnesota, at 0950. Visual meteorological conditions prevailed and no flight plan was filed.

In his written statement the pilot said, "Nearing the completion of a 360 degree turn again, I was not lined up properly. Rather than going around a second time, I attempted to force the turn, stalled, recovered nose down approximately 30 to 40 degrees, then stalled a second time attempting to lift the nose before hitting the ground."

The pilot did not indicate any mechanical anomalies in the operation of the airplane.
