Circumstances:
While cruising over Bass Strait, between Tasmania and Australia, the four engine aircraft christened 'Loina' went out of control and crashed into the sea, some 3 km off Flinders Island. All five occupants were killed.
Crew:
Arthur Evans, pilot,
Maxwell Brown, copilot.
Passengers:
G. S. Anderson,
G. Garlick,
Edward Best.
Probable cause:
It was determined that VH-URT had gone into an uncontrollable spin, and three possible precipitating factors were: a loss of control after a power plant failure, the fouling of the tail surfaces while the trailing aerial was being reeled in or a structural failure. There was also evidence of a small fire in the rear of its cabin, which may have occurred before the crash, but this probably did not factor in the accident. And in view of two fatal accidents and other difficulties with the type, Australia would subsequently suspend the certificate of airworthiness of the De Havilland 86.

Circumstances:
While overflying Bass Strait, the four engine aircraft christened 'Miss Hobart' crashed in unknown circumstances some 10 miles off the coast of the Wilsons Promontory National Park. SAR teams found some debris and oil leak at the surface of water a day later but no trace of the occupants was ever found. Captain V. Holyman, who was among the missing, was the pilot and co-founder of the airliner.
Probable cause:
The cause of the crash could not be determined. However, one of the recommendations made by the accident investigative commission was to prohibit the changing of pilots in an aircraft while in flight, since one theory into the disappearance of VH-URN pointed to a loss of control resulting from such action by the crew.
