Descripción:
Flight 1750 departed Perth (PER) at 08:29 for a flight to Port Hedland (PHE). The flight climbed to FL190, encountering light to moderate turbulence. Last radio contact was at 11:34 when the crew reported 30DME south of Port Hedland, descending from 7000 feet. The aircraft was seen to descend rapidly and steeply a little later. The wreckage was found at 28 miles from Port Hedland.

CAUSE: "The cause of the accident was that the fatigue endurance of the starboard inner main spar lower boom was substantially reduced by the insertion of a flared bush at station 143 when the margin of safety associated with the retirement life specified for such booms did not ensure that this boom would achieve its retirement life in the presence of such a defect."
