Eurocopter AS 350B3 A-Star, N357PJ, Helibro, LLC: Accident occurred July 11, 2017 in Kingvale, California

Aviation Accident Final Report - National Transportation Safety Board: https://app.ntsb.gov/pdf

NTSB Identification: GAA17CA404
14 CFR Part 91: General Aviation
Accident occurred Tuesday, July 11, 2017 in King Vale, CA
Probable Cause Approval Date: 09/22/2017
Aircraft: EUROCOPTER AS 350, registration: N357PJ
Injuries: 6 Minor.

NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

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 6 ft above the ground, the pilot felt a sudden impact, followed by subsequent impacts from the two additional rotor blades impacting what was later 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.

The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
The pilot’s failure to maintain clearance from trees while landing in a dusty, unimproved landing zone.
