Primary finding
Probable cause
The pilot's failure to maintain clearance from a wind generator tower while drying cherries, which resulted in a loss of aircraft control and subsequent hard landing.
Investigator assessment
Analysis narrative
The pilot reported that while drying cherries, he inadvertently let the main rotor blades strike a wind generator tower. The helicopter became uncontrollable, hit the ground hard, and came to rest in the orchard. The main rotor blades and airframe sustained substantial damage. The pilot reported no preimpact mechanical malfunctions or failures with the airframe or engine that would have precluded normal operation.
