Circumstances:
While descending to Zurich-Kloten Airport, the flight engineer encountered technical issues with the cabine pressure and was forced to control it manually. Focused on this problem, he failed to hear and understand the instruction of the captain to lower the gear. In such circumstances, the airplane landed on its belly on runway 16 and slid for 875 metres before coming to rest, bursting into flames. All 20 occupants were quickly evacuated and uninjured while the aircraft was damaged beyond repair. Apparently, the crew failed to hear the gear alarm.
Probable cause:
Belly landing caused by a crew error. The following factors were considered as contributing:
- Poor planned approach,
- Lack of crew coordination,
- Lack of crew concentration.

Circumstances:
After takeoff from Prague-Ruzyne Airport, while climbing, one of the engine failed. The airplane went out of control and crashed in an open field located 7 km southwest from the airport. Three crew members and eight passengers were killed while 29 other occupants were injured. The aircraft was en route from Prague to Košice with an intermediate stop in Piešťany.
Probable cause:
Engine failure for undetermined reason. It was also reported that the crew coordination and reaction to an emergency situation was inappropriate, which was considered as a contributing factor.

Circumstances:
Flight LZ101 was a scheduled international air service from Sofia to Berlin with intermediate stops in Budapest and Prague. The four engine airplane departed Budapest-Ferihegy Airport at 1146LT bound for Prague, but en route, the crew was informed the airport of Prague-Ruzyne was closed to all traffic due to poor weather conditions. So the crew decided to divert to Bratislava-Ivanka Airport where he landed at 1258LT. About 1550 hours the pilot-in-command of the aircraft decided to resume his flight to Prague. He took off from Bratislava Airport at 1628:30. After take-off he made a turn to starboard according to the flight clearance with the instruction to perform a right turn on to the OKR Beacon, to climb only to 300 m and then to climb on to the NI beacon up to the flight level of 5 100 m. At 1630:20 hours the flight was requested to change to the ATC approach service frequency, 120.9 Mc/s. The crew confirmed reception of this message, but they did not carry out the retuning. Shortly afterwards the aircraft crashed into wooded ground in the mountains. The accident occurred 8 km away from the 31 runway threshold of Bratislava Airport at an altitude of 420 m above MSL, i.e. 288 m above the airport level. The aircraft was totally destroyed and none of the 82 occupants survived the crash.
Probable cause:
The Commission could not definitely establish the cause of accident. The Commission assumed that the most probable cause of the accident was insufficient evaluation of terrain relief and weather conditions in the Bratislava Airport control zone by the aircraft crew and lack of adaptation of the flight to these conditions. There are serious reasons to doubt whether the crew thoroughly evaluated the geographical and meteorological situation and drew from this evaluation the necessary conclusions in choosing the take-off runway, in accepting the flight clearance and in performing the takeoff and the departure by making a turn to the starboard on to the OKR beacon. The possibility must be admitted that the non-maintenance of the 15° bank and the 400 km/h speed (or the lowest possible limit of 360 km/h), which non-maintenance had a causal connexion with the accident, could be partly due also to errors in controlling and navigating the aircraft.

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.

On approach to Prague, the crew encountered poor weather conditions and was forced to make a go around. During the next hour, four other attempts to land were aborted. Finally, the captain informed ATC that he was short of fuel and was forced to make an emergency landing. The aircraft crash landed in a field located in Dobrovíz, two km north of the airfield. All 18 occupants were evacuated, two of them (both crew members) were injured. The aircraft was damaged beyond repair. The ETA in Prague was 1535LT and the accident occurred at 1736LT. The crew of a Pan Am Constellation who should land in Prague decided to continue to Brussels due to poor weather conditions.
