The pilot had planned the direct track for the flight from Cockatoo Island to Derby at 5500 feet above sea level. When the pilot gave his DEPARTURE call he amended his cruising level to below 5000 feet. No further calls were received from the aircraft. The Cockatoo Island work boat was 56 kilometres north-north-west of Derby, and approximately 20 kilometres west of the direct track between Cockatoo Island and Derby. The crew of the boat observed an aircraft approaching at very low level. The aircraft passed over the boat approximately 5-7 metres above the deck, and entered a right hand turn. During the turn the right wing tip struck the water causing the aircraft to cartwheel and crash about 400 metres from the boat. The fuselage broke open on impact and the occupants were subsequently rescued by the crew of the boat. The pilot declined to provide any information which might have clarified the circumstances of the accident, however, available information indicates that he carried out an unauthorized low pass over the boat. During the turn following the low pass, he misjudged the aircraft's height and the right wing tip struck the water.
