Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, after landing the helicopter in an empty parking spot, he realized that the helicopter was oriented with a tailwind. He decided to reposition the helicopter, and shortly after liftoff, he felt a strong wind gust from the left. The helicopter's right skid then impacted the ground, and the helicopter dynamically rolled over. The helicopter sustained substantial damage to the fuselage, tailcone, and horizontal stabilizer. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
