What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Setting up for the approach, the pilot detected a strong tailwind while on downwind, but not strong enough to be alarmed. The terrain was hilly and the approach path was over a basin. Turning and descending on left base, the helicopter began to drift from the south wind. As the pilot added collective pitch to control the descent rate, the helicopter began to settle. The helicopter entered a settling with power condition. The decision to make a run-on landing was made. The helicopter skids made contact with the tussock-filled tundra which resulted in a dynamic rollover. The helicopter rolled onto the starboard side.
