German Federal Bureau of Aircraft Accident Investigation (BFU) released first information, related to
OK-ACH registered Time Air Cessna 550, departed Prague at 20:08 on 14.02.2010 for a ferry flight to Karlstad. At 20:19, the aircraft's radar signal vanished from the monitors of the Air Traffic Service Provider. The crash site was found during the night close to the village Reinhardtsdorf-Schöna in the area of the mountain Großen Zschirnstein, Saxony. In the following few days rescue work was under way during which the Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR) were recovered. Analysis of the Cockpit Voice Recorder showed evidence that shortly before the crash an aerobatics manoeuvre (barrel roll) was initiated. The aircraft was neither designed nor approved for such manoeuvres. The BFU issued safety recommendations, that the CAA-CZ responsible for air operators within the Czech Republic should arrange for an inspection of the involved air operator's aircraft in regard to structural overload and it should determine actions for the improvement of the air operator's Quality Management System and the Safety Culture. The investigation into the accident by the BFU is still in progress.
