Circumstances:
The crew (two pilots, one radio operator and one instructor) were engaged in a local training sortie at Hradec Králové Airport. While cruising at an altitude of about 200 meters, the left engine failed. The crew elected to return for an emergency landing when completing a last turn to the right, the aircraft stalled and crashed in a field located in Rusek, east of the Airfield. The radio operator was seriously injured while three other occupants were killed.
Probable cause:
Failure of the left engine caused by a malfunction of the spark plugs.

Circumstances:
After a takeoff roll of 900 meters on runway 22, the pilot-in-command initiated the rotation. While climbing to a height of about 50 feet in a horizontal visibility of about 100 meters, the crew sighted the chimney and the pilot made a sharp turn to the left to avoid a collision. Doing so, the airplane hit a telephone pole and telegraphic cables, stalled and crashed in flames in a snow covered field located about one km south of the airfield. All four crew members and nine passengers were killed while five other passengers were rescued. The aircraft was destroyed.
Crew:
Jan House, pilot,
Jiří Levý, copilot,
Milroslav Kalenda, radio operator,
Milroslav Häusler, flight engineer.
Probable cause:
No mechanical failure was reported on the airplane prior to the accident. At that time, the cloud base was about 200 meters above ground with a horizontal visibility of 100 meters in snow falls. The takeoff roll was completed on runway 22 that was covered with a layer of 5 to 10 cm of wet snow. The accident was the consequence of poor flying techniques on part of the pilot-in-command during initial climb.

Captain / Total flying hours:
1300
Circumstances:
During the takeoff roll on runway 27, the aircraft reached the speed of 140-150 km/h when the pilot started the rotation. Shortly after takeoff, while climbing to a height of about 30 feet, the aircraft turned slightly to the right and it is believed that the right engine lost power. The pilot-in-command made a turn to the left, raised the flaps and nosed down to gain speed that increased up to 200 km/h when the aircraft hit the ground and eventually crashed in a field. While all three crew members were uninjured, the aircraft was damaged beyond repair.
Crew:
Lt Ernest Trabatický 2.
Probable cause:
No technical anomalies were found on the aircraft and the cause of the accident was attributed to a pilot error.

Circumstances:
The crew left Hradčany AFB at 2147LT for a local training flight with two other Aero C.3. While flying at an altitude of 1,000 meters, the right engine lost power. The captain activated the fuel pump when a fire erupted. He descended to the altitude of 400 meters when both other crew members bailed out. Sole on board, the pilot tried to land on runway 09 but on final approach, the aircraft hit trees and crashed in flames in a field short of runway 09 threshold. The pilot was killed and the aircraft was destroyed by fire. Both other crew members were unhurt.
Crew:
Maj Jan Kopečný, †
Cpt Miroslav Kořínek,
Lt Miroslav Hladník.
Probable cause:
It was determined that the day prior to the accident, the aircraft was grounded for maintenance purposes (50 hours overhaul). While conducting the maintenance of the right engine, the mechanic was fired. Investigations revealed that the other technicians in charge of the maintenance failed to check what was done by the mechanic and the airplane was released without any double check. It appears that several equipment such as fuel pump and piston were not properly fixed.

Circumstances:
The crew was performing a cargo flight in Czechoslovakia, carrying a load of newspapers on behalf of the national career CSA Czech Airlines. While on a night approach to Brno-Tuřany Airport, the aircraft hit the slope of Mt Bradlo (548 meters high) located in the Chriby Mountain Range, about 2,5 km northwest of Vřesovice. The wreckage was found 35 km east of Tuřany Airport and all five crew members were killed.
Crew:
Větroň Antonín,
Antal Viliam,
Dvořák Jiří,
Gregr František,
Koval Vlastimil.
Probable cause:
Following several errors, the flying crew started the descent prematurely. At the time of the accident, the aircraft was at an insufficient altitude of 550 meters instead of the minimum altitude fixed at 1,800 meters in this area. Low visibility caused by night and marginal weather conditions prevented the crew to see the mountain, which was considered as a contributory factor. The Czech Authorities confirmed that the flight should normally be scheduled by the national career CSA but due to poor weather conditions, the CSA crew refused to fly. Thus, a military crew was engaged for this flight despite his lack of training in such weather conditions.
