Aircraft Accident/Incident Report

Idaho Falls, Idaho 83402
Tuesady, July 22, 1997 8:13 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot requested 15 gallons of fuel and 30 gallons of fungicide prior to takeoff, but was fueled with 40 gallons of fuel and 40 gallons of chemical by his ground crew. He then lifted off with a tailwind during which the rotorcraft settled to the ground, the right skid collapsed and the tailboom separated. The density altitude was approximately 5,500 feet.

NTSB Probable Cause Narrative

The pilot-in-command's failure to verify the proper chemical and fuel load aboard prior to takeoff. Factors contributing to the accident were: excessive fuel and chemical loading by ground personnel, tailwind conditions, and high density altitude.
