Accident Details
Probable Cause and Findings
The pilot’s failure to maintain clearance from trees while landing in a dusty, unimproved landing zone.
Aircraft Information
Registered Owner (Historical)
Analysis
The pilot of the helicopter reported that, during the landing on the unimproved dirt parking lot, dust started to kick up, and he transitioned to looking through the "chin bubble" for a visual point of reference. When the helicopter was about 5 to 6ft. above the ground, the pilot felt a sudden impact, followed by subsequent impacts from the two additional rotor blades impacting what later was found to be a tree. The helicopter "violently" fell to the ground and rolled onto its left side.
The helicopter sustained substantial damage to the fuselage and main rotor system.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
