Winterburn - Winterburn

The aircraft took off at approximately 1700LT on a local test flight carrying a crew of 2 and 4 passengers. The purpose of the flight was to test the single-engine performance of the aircraft when loaded to the maximum permissible weight for take-off and to determine the correct power setting and performance. Just before 1705LT witnesses stated that they saw the aircraft turn onto its back with a sudden cessation of engine noise and white or grey vapor was seen to come from both engines as it dived in a very steep nose down attitude to the ground. From statements of witnesses it was deduced that it was probable that the aircraft was below 1,000 feet when it turned onto its back. The aircraft exploded on impact and caught fire. All the occupants were killed and the aircraft was destroyed.
