What happened
During a flight from Innsbruck to Zurich (Dübendorf), the pilot encountered deteriorating weather conditions that necessitated an immediate response. Unable to continue safely, the crew initiated an emergency landing procedure. However, the aircraft failed to maintain control or altitude sufficiently to reach a safe surface, resulting in a collision with the terrain. The impact caused the airframe to come to rest almost upside down.
The accident resulted in fatal and non-fatal injuries among the occupants. One fatality was confirmed, involving the pilot, while both passengers sustained injuries. No specific aircraft registration or model is provided in the available source material.
