Nearing the completion of a survey flight over a mining prospect, the pilot asked the passengers if they would like to see a crop dusting manoeuvre. As the passengers had no objection, the pilot flew the helicopter through a steep 180 degree climbing turn to the left from a height of about 300 feet. During recovery from the ensuing dive, the aircraft struck the ground heavily and came to rest inverted. The surviving passenger was thrown from the aircraft after the initial impact. There was no evidence of any mechanical defect in the helicopter which may have contributed to the accident.
