Accident Details
A pilot and a gunner were engaged in a predator control flight for the State of South Dakota Department of Game, Fish, and Parks. The purpose of the flight was to chase a coyote out of a 'slew' into an alfalfa field. During the maneuver, the aircraft entered a left, slightly descending turn at an altitude of 150 feet above ground level. According to the pilot, the control stick then went 'limp.'
Pilot Actions and Impact
The pilot reported adding full power, leveling the wings, and applying forward stick pressure in an attempt to regain lift. Despite these actions, the airplane continued to descend and impacted the edge of the alfalfa field in a wings-level attitude. Upon impact, the main landing gear separated from the airplane. The aircraft slid approximately 60 feet before nosing over.
Weather Considerations
The pilot indicated a suspicion that wind shear caused the accident. Weather reports from a station 30 miles northwest of the accident site recorded winds from 140 degrees at 7 knots.
Investigation Notes
The investigation did not provide a probable cause. The aircraft type, registration, operator, and other specific details were not disclosed in the source material.
