Update: The official AAIB report into the accident was published on 6 December 2018, and the following is an excerpt from it...
"The owner of G-FMKA was undertaking a biennial refresher training flight with an instructor for the purposes of revalidating his class ratings. On the day of the accident flight, the owner flew the aircraft solo from Nympsfield, where the aircraft was based, to Draycot, arriving around 17:45 hours.
The instructor had flown on three other instructional flights from Draycot earlier that day, after which he was asked to conduct this flight. The accident flight was the first time that the instructor had flown in a Super Dimona. Shortly before the flight, the instructor and owner were seen in discussion; however, the content of their discussion is unknown. The precise planned content of the flight could not be established, except that the intended length of flight was one hour.
A witness at Draycot observed what appeared to him to be normal control and engine run-up checks on the aircraft; this included operation of the airbrakes. The aircraft took off from Draycot at 1810 hrs and was seen to depart to the south, towards Marlborough.The airfield had a radio, but no RT calls were received from the aircraft and none were expected.
At approximately 1820 hrs, what is believed to be the accident aircraft was seen over Marlborough by a witness who held a PPL. He stated that he thought the aircraft was at around 1,000 ft agl and heading south. The engine could be heard running, the aircraft was in wings-level flight and all appeared normal. Shortly thereafter, the aircraft was seen manoeuvring in the vicinity of the accident site by several other eyewitnesses.
All of the witnesses felt that their attention was drawn to the aircraft because it was much lower than expected. The witnesses, who were widely dispersed, also reported hearing engine noises.
Some witnesses described the engine noise increasing in the latter stages of the flight. There was a consistent view that the aircraft was in a left turn in the latter stages of flight. The closest witnesses to the accident site described the aircraft as being perhaps only 100 ft agl as it passed their house, approximately 400 metres from the accident site, and believed it was going to land.
Another witness described the aircraft as “spinning around one wing and looked very nose‑down” before his view was obscured by trees. The accident site was surrounded by tall trees on three sides and none of the witnesses saw the aircraft hit the ground. The accident site was located approximately 7 miles from Draycot
Witnesses described impact noises, followed by a small cloud of dust or smoke. Several witnesses made calls to the emergency services at approximately 18:30 hours. Witnesses who went to the accident site saw a small fire in the wreckage which then spread to the field’s barley crop. Workers from the nearby farm used farm machinery to cut a firebreak to limit the spread of the fire. The two occupants had suffered fatal injuries."
Damage sustained to airframe: Per the above AAIB report *aircraft destroyed". As a result, the registration G-FMKA was cancelled by the CAA on 9 March 2018 as "de-registered". The registered owner was one of the two killed in the accident.
