Narrative:
Robinson R22 Beta ZK-HTD, c/n 0223, struck the terrain courtesy of a downdraught in the Paparoa Ranges, on 11-03-2010. According to the official CAA NZ summary (see link #1):

"The pilot was operating the helicopter on a private scenic flight in the Paparoa ranges, west of Reefton. He had slowed the helicopter to view a black mark on the hillside, when he encountered a downdraft. This resulted in a low rotor RPM situation. The pilot was unable to recover the RPM and the helicopter descended onto the hillside and rolled over on its right side.
