The very first flight by Batik Air from Bali to Canberra arrived in darkness before the traffic control tower had started operating for the day. The result was a series of failures to communicate clearly between the pilot and people on the ground as the plane flew below safety limits.
These are the preliminary findings of the official investigation by the official Air Transport Safety Board.
"Forecast tailwinds resulted in an estimated arrival time just prior to 0600 on 14 June, which was earlier than planned, and before Canberra Tower and Canberra Approach air traffic control commenced services for the day," the ATSB said.
