On a more positive point, the PNG AIC have released the preliminary accident report. I have no idea how one could get a copy as they don't appear to have a website, there is nothing on the ATSB website. Super Sid was interviewed yesterday and it was aired on the EMTV news last night. No mention was made of a pre impact onboard fire, although what Sid clearly stated was that both engines appeared to loose all power due to both the props over speeding up to 60% over max RPM simultaneously.
He also indicated that the investigation team still have not pinpointed the root cause of the prop over speeds.
