Accident Overview
An ambulance flight from Frankfurt to Genoa to pick up a patient struck the northeast face of Mt Le Grammont (2,172 meters), located six kilometers northwest of Vouvry. The wreckage was found less than ten meters below the summit. Both crew members, Captain Johann-Christian Jessen (pilot) and Niels-Michael Seierde (radio operator), were killed.
Flight Sequence
After passing over Bern, the crew was authorized to descend to 6,000 feet. While passing over the Lake of Geneva, weather conditions worsened. At an altitude of about 5,600 feet, the airplane went through clouds and the pilot made a left turn of 20° for unknown reasons. The airplane then struck the mountain.
Weather Conditions
Weather conditions at the time were described as poor, with icing conditions present.
Investigation Findings
The exact cause of the accident could not be determined with certainty. However, the investigation noted poor weather and icing conditions, and the possibility that the accident resulted from a navigation error on the part of the crew was not ruled out.
