Cat. 2 investigation report: simplified-format report, adapted to the circumstances of the occurrence and the investigation stakes.
The pilot made his maiden flight on board the microlight that he had built. During the turn before the end of the initial climb, the microlight stalled asymmetrically to the left then collided with the ground.
In the absence of documentation for the microlight, the hypothesis of a technical failure or a flight instability of the microlight that had not previously been tested, could not be ruled out by the examination of the wreckage. However, the investigation showed that the pilot’s health had deteriorated due to coronary disease and that he was suffering from a new evolving cardiac event at the time of the flight. It is likely that this infarction resulted in an incapacitation that meant that he could not maintain control of the microlight.
