The four survivors from yesterday's airplane crash in Papua New Guinea's Madang province are now in hospital, one in a critical condition.
As many as 28 people are feared to have died after the Airlines PNG Dash-8 aircraft crashed near the mouth of the Gogol river, about 20 miles south of Madang town.
PNG's Accident Investigation Commission has begun an investigation into the crash.
The Commission's chief executive, David Inau, has confirmed the plane went down in stormy weather.
"That's a factor we're looking at. I am also informed that was weather ni the area. So that's an area we will be investigating as well. But there are checks and systems in place to ensure the aircraft are operated in accordance with their operating certificate requirements."
Airlines PNG has grounded its fleet of 12 aircraft until further notice.
