What happened
During the final stages of an approach to land, a HB-FAX aircraft encountered significant crosswinds. While on short final, the plane entered a stall and impacted the ground within the runway threshold area. Although the impact caused the aircraft to be damaged beyond repair, there were no fatalities or injuries reported among those on board.
Findings
An investigation into the accident revealed that the fuel selector valve had been set to the lower tank. Due to the specific attitude of the aircraft during its final approach, this configuration prevented sufficient fuel from reaching the engine. This fuel starvation was a critical factor in the loss of power that led to the stall.
