NTSB Final Report: Lucerne Valley, California

Location: Lucerne Valley, California
Accident Number: WPR21LA133
Date & Time: March 16, 2021, 07:45
Local Registration: N6133C
Aircraft: Bell 206
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 2 Minor
Flight Conducted Under: Part 91: General aviation - Personal

Analysis
The pilot reported that he departed from a dry lakebed with the intention of making a local flight for the passenger to photograph the area. He noted that the wind was from the southwest  between 12-15 kts. After departure, the pilot was maneuvering the helicopter to the southeast about 300 ft above ground level (agl), where he was using the helicopter controls to compensate for a tailwind. The helicopter began to yaw to the right and the pilot attempted to regain control by applying full left pedal. Despite his attempts, the helicopter continued to rotate, and the yaw rate was increasing in speed. The helicopter descended and when it neared the ground, the pilot flared to cushion the touchdown for the rapid descent rate. The tail collided with the ground,  followed by the skids contacting the desert floor hard; the helicopter came to rest on its right side. The fuselage and tail boom were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation. 

Probable Cause and Findings
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's failure to maintain aircraft control while maneuvering with a tailwind, resulting in the helicopter spinning and colliding with terrain. 

Findings
Aircraft Yaw control - Not attained/maintained
Personnel issues Aircraft control - Pilot
Aircraft Directional control - Not attained/maintained
Environmental issues Tailwind - Ability to respond/compensate
