Narrative:
The purpose of the flight was to land a passenger and gear beside a mountain lake (Lake Isobel 21 km west of Queenstown, at 45"014' S, 168"288' E) at an elevation of 5,300 feet amsl. On short final approach, the pilot found that, on losing transitional lift the rotor rpm began to decay, and she was unable to arrest the sink. An attempt to make a controlled landing on lower, uneven, ground was unsuccessful. The left skid collapsed and the helicopter rolled over. Neither occupant was injured.
