Engineering error....frozen bolt found but not removed....nut replaced and aircraft released for flying. The item was due time change in nine hours of flying but failed on the next flight. The aircraft crashed into a canal or river and sunk immediately. Survivors did an underwater escape to get out of the aircraft.
Chris Cairns survived the crash along with some passengers.
Was on a drive link if I recall properly.
Not a good day by any description beyond some did survive.
Perhaps Stacey or someone knowledgeable about the actual sequence of events can give us a summary of what happened.
