The investigation into last month's plane crash in Papua New Guinea has produced an interim report but the cause of the accident will not be announced for at least another six months.
13 people, including nine Australians, died when their Airlines PNG Twin Otter crashed in the Owen Stanley Ranges on its way to the Kokoda track on August the 11th.
The Civil Aviation Minister, Charles Abel, has told a news conference in Port Moresby that the initial report merely states the factual circumstances.
He says it's too early to make any determinations.
The Accident Investigator, Sid O'Toole, says the investigation will be a watershed moment in PNG's air safety history, considering the resources, commitment and assistance from both PNG and Australia.
