Cat. 2 investigation report: simplified-format report, adapted to the circumstances of the occurrence and the investigation stakes.
The pilot, accompanied by an instructor, took off for an advanced aerobatic training session overhead the aerodrome.
An overcast layer of stratocumulus cloud was present at 2,200 ft AGL, i.e. 2,400 ft AMSL. At the start of the flight and due to a simultaneous glider winch launch activity, one of the occupants announced to the duty AFIS officer that they would be flying above 2,500 ft AMSL. However, according to the statements, the aeroplane had remained below the cloud layer for the duration of the flight.
After around 10 flight minutes, when it was north of the aerobatic zone and coming back towards it, still under the cloud layer, the aeroplane entered a left spin and then collided with the ground.
