The final report into the incident involving the Air Corps helicopter AW139 on 2 March 2009 was provided to me by General Officer Commanding Air Corps on 11 June 2009.
The final report was compiled following a detailed investigation into the incident by the Air Corps Military Airworthiness Authority. The investigation included interviews with the crew and passengers of the aircraft. The aircraft was fit for flight, and was crewed by a fully authorised and qualified flight crew.
The investigation determined that the left hand cabin door was not properly closed and locked following the last opening on the ground prior to the incident flight.
There is no suggestion in the report that the aircraft passengers were in any way responsible for this incident.
