The lead accident investigator investigating this accident has been with the ATSB for over 10 years. He was at the accident scene the day after it happened.
Before joining the ATSB he was with Sikorsky as a Field Service Rep (Tech Rep) in Australia and before that he was attached to the Thai Navy as the on site Field Service Rep for their Seahawks. He has years of helicopter experience before that both in Sikorsky (working as an engineer in their production facility) and the US Military. He probably has over 30 years in the industry.
