Circumstances:
About thirty minutes after his departure from Ostrava Airport, the crew encountered poor weather conditions with drizzle, low visibility and strong winds gusting to 90 km/h.

Three crew members and two passengers were killed.
Crew killed were:
Vaclav Soukup, pilot,
Augustin Korotvička, radio operator,
Richard Olšovský, flight engineer.
Passengers killed were:
Jan Kloda,
Ladislav Škrabálek.
Probable cause:
The accident was the result of a faulty navigation on part of the crew. Low visibility caused by poor weather conditions was considered as a contributory factor.

Circumstances:
The crew completed several maneuvers during the day, taking part to a training mission combined with a second Czech Air Force Aero C.3 registered S-11 and carrying a crew of seven as well. In the afternoon, both crew were instructed to stay at Prostějov due to poor weather conditions. At 2230LT, the headquarter informed both crew they were able to fly back to Chrudim as the weather improved. En route, both airplanes went out of control and crashed in the same time. S-11 crashed in a field northwest of Jaroměřice while S-15 crashed in a wooded area located on km southwest of Jevíčko. All 14 crew members on both aircraft were killed.

Zděnek Kolaček.
Probable cause:
At the time of the accident, weather conditions were marginal with the presence of a cold front. Both aircraft went out of control at the same time, apparently due to downdraft, turbulences or weather factors. According to the Czech Authorities, it seems unlikely that the fall of both aircraft is the consequence of a collision in flight. Analysis on S-15 revealed that the aircraft hit the ground at high speed, nose first (angle down to 75°) without its left wing.

Circumstances:
On approach to Prague-Ruzyne Airport, when the aircraft broke through the clouds, it was deviated by 300 meters to the right of the runway centerline. Rather than making a go around, the pilot completed a steep turn to the left to join the runway but on final, the left wing hit the ground and the aircraft came to rest in a grassy area to the right of the runway. While all occupants escaped uninjured, the aircraft was damaged beyond repair.

Circumstances:
The aircraft left Prague-Kbely Airport in the early morning with a crew of three and three engineers on board, bound for Liberec where they should take part to a meeting. While descending to Liberec in poor weather conditions (heavy rain falls), the twin engine aircraft hit the slope of Mt Ještěd few meters below the top and came to rest in flames. Two passengers were seriously injured and evacuated to a local hospital while four other occupants were killed. Six days later, one of the survivor died from his injuries. The visibility was very limited due to heavy rain falls and low ceiling.
Crew:
Václav Barborka, pilot,
Jan Padouch, radio operator,
Josef Kroulík, navigator.
Passengers:
Antonín Husník (survived but died 6 days later),
Vladimír Karmazín, killed,

Circumstances:
Enroute from Bucharest to Prague, the crew encountered poor weather conditions with low clouds. The pilot lost his orientation due to fog and decided to reduce his altitude to establish a visual contact with the ground when the aircraft hit tree tops and crashed in a dense wooded area. Thirteen passengers were rescued, among them Arel Grigoresco, ambassador of Romania in Prague, while thirteen other occupants were killed, among them all five crew members.
Probable cause:
Due to poor weather conditions, the crew decided to fly at an insufficient altitude, neglecting navigational rules. It appears that radio failed in flight, which was considered as a contributory factor.
