Synopsis
On 2 June 2021, the AAII was notified by the Rescue Coordination Centre of an air accident of the above mentioned aircraft. During a navigation flight from České Budějovice to Příbram, a passenger began experiencing airsickness. The pilot decided to land in the field. During the landing, the aircraft in the landing run turned over. The pilot and the passenger were not injured. Following the air accident, the aircraft was damaged to a large extent.
Preparation for flight, based on the testimony of the pilot of the event flight
Approximately one week before the flight, the flight was being prepared with two pilots along the following flight route:
EDNA Waldkrauburg (Germany, 30 km E Munich) – EDNB Arnbruck (Germany, 15 km W Železná Ruda) – EDPS Sonnen (Germany, 20 km N Passau) – LKCS (Czech Republic, České Budějovice) – LKPM (Czech Republic, Příbram) – LKLN (Czech Republic, Líně) – LKLT (Czech Republic, Klatovy) – EDNB – EDNA.
The NOTAM preparation was conducted during the stated preparation for the flight and also the night before the flight.
The entire route was prepared and discussed by both the pilots.
The meteorological preparation was carried out in the morning on 2 June 2021.
VFR maps covering Germany and the Czech Republic were available on board for navigation purposes.
Flight day on 2 June 2021, based on pilot’s testimony
Flight 2: EDNB TO 08:25 DCT EDPS LDG 09:23 Passenger, also pilot (with the pilot of the event flight travelling as a passenger)
Flight 3: EDPS TO 09:23 via Plöckenstein, Moldau LKCS LDG 10:04 Pilot of the event flight (with a passenger who was also a pilot)
Event flight, the fourth flight on the same day, based on the event flight pilot’s testimony
Flight 4: LKCS TO 10:43 DCT LKPM, LDG by Stěžov 11:18 Pilot of the event flight (with a passenger who was also a pilot).
The fourth flight was troubled due to thermal effects. The passenger, who is also a pilot, was helping with navigating using charts. He was experiencing dizziness due to the turbulence and visual contact with the on-board navigation aids. He requested the pilot to land immediately. The pilot identified a dry field and performed landing in the westbound direction. After the landing and brakes release, the nose wheel dug into the ground and the front landing gear leg broke. The probable speed was 30 km/h. The aircraft rolled over the nose and landed on its back. Both pilots disembarked the aircraft uninjured. The pilot reported the occurrence by telephone to PRAGUE Information.
