Primary finding
Probable cause
The pilot's inadequate compensation for gusty crosswinds during takeoff, which resulted in a loss of directional control.
Investigator assessment
Analysis narrative
The pilot reported that he was landing his helicopter. He transitioned to a hover at about three feet above the ground. The helicopter encountered a sudden gust of wind that blew the helicopter forward and down. The left skid impacted the ground and the helicopter turned to the right and rolled over onto its left side. The helicopter sustained substantial damage to its fuselage and tailcone. The recorded wind conditions indicated gusts from 15 knots to 19 knots. The pilot reported that there were no preimpact mechanical malfunctions with the helicopter.
