Overview
On a charter flight from Egelsbach Airport, a twin-engine aircraft departed at 1743LT with one passenger and two pilots, bound for Friedrichshafen-Bodensee Airport. The flight was uneventful at Flight Level 210 until the crew contacted Zurich Air Traffic Control Center and received clearance to begin descent, with a planned ILS approach to Runway 24.
Descent and Loss of Control
After descending past 4,000 feet at a speed of 240 knots, the crew was completing a turn in clouds when the aircraft entered a rapid and uncontrolled descent. The airplane crashed in a wooded area near Sieberatsreute, approximately 15 kilometers short of the runway threshold. The impact was severe, resulting in the disintegration of the aircraft and fatal injuries to all three occupants.
Investigation Findings
The official investigation concluded that the accident was caused by a sudden loss of control while turning in clouds at night. It was noted that frontal weather conditions, including light to moderate turbulence, snowfall, and icing, likely contributed to the incident. However, due to the lack of recorded data from onboard systems, the precise factors leading to the loss of control could not be determined.
