Cat. 2 investigation report: simplified-format report, adapted to the circumstances of the occurrence and the investigation stakes.
After taking off from Albertville aerodrome, the pilot started the climb towards the Belledonne massif. He flew over the town of Aiton then entered a cirque heading towards a pass in the vicinity of Montgilbert Fort. As he was approaching the pass, he realised too late, whilst still in climb, that the aeroplane’s altitude would not be sufficient to clear it. Estimating that he could not turn back due to the terrain, the pilot attempted to gain altitude by increasing the aeroplane’s attitude. This resulted in a reduction in speed towards the stall speed. He next initiated a turn to the left to fly parallel to the ridge line, thus reducing the stall margin once again. He then found himself facing the western slope of the second ridge line. The aeroplane collided with the pine trees and ended its course in the snow.
