Incident Overview
A pilot conducting a predator control flight experienced a loss of control shortly after initiating a climbing left turn, resulting in substantial damage to the right wing of the airplane. The pilot reported that the event occurred about 75 feet above ground level, following a right turn to the west.
Pilot Report
According to the pilot, after completing the right turn, he began a climbing left turn to the east. At approximately 75 feet above the ground, the airplane "banked violently to the right and back to the left about two-three times," then descended and impacted the snow-covered terrain. Post-impact inspection revealed that the right wing sustained substantial damage.
The pilot stated that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Post-Accident Review
The hiring agency's check pilot conducted a post-accident flight review with the accident pilot. During this review, the check pilot observed that the pilot did not apply rudder inputs during turns, steep turns, and stall recovery procedures.
Conclusion
The accident sequence involved a loss of control at low altitude with oscillations prior to impact. The aircraft's right wing was substantially damaged. No mechanical issues were identified by the pilot. The hiring agency's check pilot noted a lack of rudder usage during specific maneuvers in a subsequent flight review.
