What happened
The flight originated in Amsterdam and proceeded without incident until the crew began their final approach to Essen-Mülheim Airport. Visibility was significantly reduced by foggy conditions during this phase of flight. As the aircraft descended on final, it was positioned too low for its trajectory. Consequently, the airframe collided with the chimney of a factory situated near Kettwig.
Following the impact with the structure, the aircraft entered a stall and crashed into an open field located approximately 3 km southwest of the airfield. The accident resulted in fatal injuries to all three crew members on board. The three passengers sustained non-fatal injuries.
Findings
The primary contributing factor identified was the low altitude of the aircraft during the final approach segment, which occurred under conditions of limited visibility due to fog.
