A helicopter performing herbicide spray patterns experienced a loss of altitude during a turn, touched down, spun, and rolled onto its left side. The tail boom sustained substantial damage; no pre-impact mechanical issues were reported.
Accident Description
According to the helicopter pilot, he was completing north-south herbicide spray patterns with winds varying from east to south at 4 to 5 mph. As the pilot positioned the helicopter for the next northern track, he began to feel the aircraft lose altitude after the turn. He stated that he tried to regain control by pushing forward the cyclic and lowering the collective to "get out of the settling with power." When ground contact was imminent, he raised the collective to cushion the impact. The helicopter touched down, spun, and rolled onto its left side.
Examination Findings
Post-accident examination by a Federal Aviation Administration inspector revealed substantial damage to the tail boom. The pilot stated that there were no pre-impact mechanical malfunctions.
