A pilot declared an emergency after both engines stopped due to fuel exhaustion on approach to Karlstad Airport. The aircraft crashed into Lake Vänern, killing the pilot and four passengers.

Incident Overview and Emergency Declaration During the approach to Karlstad Airport, the pilot notified air traffic control that the aircraft was low on fuel. Shortly after this communication, the pilot declared an emergency when both engines stopped. The aircraft subsequently lost altitude and crashed into Lake Vänern, which is located 12.5 kilometers from Karlstad Airport. The incident resulted in the deaths of the pilot and four passengers, while three other passengers were rescued. ## Official Findings and Contributing Factors The official investigation determined that the accident was caused by a double engine failure due to fuel exhaustion. This failure occurred because the pilot did not refuel the aircraft before the flight or make a fuel stop en route. Contributing factors included the engines stopping before the aircraft reached its destination, the flight being initiated with an insufficient amount of fuel on board, and the pilot deviating from current Danish regulations regarding the prescribed minimum amount of fuel.
