Avro Anson A4-32 of 6 Squadron RAAF crashed at Riverstone, NSW on 28 April 1939.Four men were killed.
After leaving Richmond Airfield the Avro Anson was flown out to sea in the vicinity of Smith Head, Sydney. The crew maintained constant radio communication with the airfield and the flight proceeded without incident until approximately 3:30pm. At 3:27pm a radio message was received from the aircraft to the effect that the aerial was being reeled in preparatory to landing. At that time the aircraft was within a few miles of the airfield and within a few minutes of landing. This was the last message received from the aircraft.
At 3:30pm Avro Anson A4-32 crashed into the ground. There were several eye witnesses. It would appear the aircraft was flying in normal level flight at about 1,000 feet when eye witnesses heard some spluttering from the engines along with the noises of backfiring and puffs of smoke were seen coming from the aircraft.
The nose of the Avro Anson dropped to an angle of 30 degrees and it started to lose height. Eye witnesses then indicated they could hardly hear the noise of the engines but they then made a sudden roaring noise and the nose pulled up again.. But then it went into a steeper dive and crashed directly into the ground with its engines roaring.
