The pilot was in current flying practice but neither his licence nor medical were valid. The aircraft maintenance records were incomplete and there is therefore a lack of evidence to show that the required maintenance was correctly performed on the aircraft. Despite this, the accident appears to have been as a result of a loss of control while the pilot was attempting an aerobatic manoeuvre, and not as a result of a mechanical failure in the aircraft. .
This was the final conclusion in the AAIB report. Not having a current licence, medical, maintenance is not in itself a cause of an accident although it can be, but doesnt appear to be relative to this accident.
I tend to go with SallyAnn that the lack of licences and maintenance is more indicative on the attitude of the pilot which resulted in a crash which took the lives of the two passengers and left their children without parents.
Those kids will be looking to an insurance claim which will not be forthcoming so I presume they will have to claim against his estate.
Interesting is the AAIB made no recommendations on checking licences, medicals etc citing the fact that you would not ask to see a car drivers licence before accepting a lift ???
