What happened
A twin-engine airplane was conducting a flight from Bern-Belpmoos Airport to Samedan on behalf of the Service Technique du Département Militaire Fédéral - Mensuration Cadastrale Suisse. During the final approach phase toward Samedan Airport, the aircraft experienced an aerodynamic stall. This led to the plane crashing into a field situated approximately five kilometers before reaching runway 21.
The accident resulted in one fatality among the occupants, while the remaining two survivors were successfully rescued from the wreckage.
Findings
Official reports indicate that the loss of control during the final approach was triggered by an engine failure.
