What happened
The incident involved an aircraft operating as a delivery flight between Lake Maggiore and Finland. The plane departed its origin point in the early morning hours with two individuals on board. While traversing the Alpine region, the aircraft lost control and impacted the terrain on the Gliems Glacier, located in the Toedi area of Glarus. Both occupants were killed in the crash. Their remains were subsequently transported to Zurich, where they were cremated four days after the accident.
Findings
Swiss authorities investigated the cause of the disaster and determined that the accident resulted from the disintegration of the wooded propeller while in flight. The investigation concluded that this failure was due to a faulty gluing method used during the manufacturing process by Savoia. The official findings further indicated that this defect was the result of sabotage.
