A HELICOPTER crew scanning the crash site of a plane that was flying over Papua New Guinea's Kokoda Track has reported "no immediate signs of activity'' at the scene.
Seven Victorians and two Queenslanders intending to walk the iconic track with the No Roads Expeditions trekking company, were among 13 people aboard the Twin Otter charter aircraft that went down in mountainous country in the Owen Stanley ranges yesterday.
In a written statement, Airlines PNG said their plane was found at 8.40am (8.40 AEST) today.
"The missing aircraft was found at an altitude of 5,500ft (1,676 metres) in the Kokoda area.
"Visual inspections from a helicopter showed no immediate signs of activity.
"A PNG Police response team landed a short distance from the site, but deteriorating weather and limited communications have hampered further information from this team,'' the airline said.
Three helicopters, including a Royal Australian Navy Sea King are in the area, with the intention of landing further personnel to assist.
At least it has been found - now the really difficult part begins and it is not looking good re survivors
