From the Wikipedia article
The 1954 ČSA accident near Bratislava occurred on 12 December 1954. On that day a Douglas DC-3/C-47A of ČSA, which had taken off from Prague Airport and made an intermediate landing at Brno Airport, crashed on approach to Bratislava Airport. All four occupants of the aircraft were killed in the accident.
Accident sequence
The flight was conducted in the late evening hours and in darkness. The leg from Prague to Brno was flown without any particular incidents. At 22:42 the crew contacted air traffic control in Brno and requested clearance for an approach to runway 23 of the airport, which was granted immediately.
While flying a turn to bring the aircraft onto the approach course, the aircraft struck terrain at an altitude of 200 metres above sea level and burned out. All four occupants were killed. The accident site was near Pezinok, at a distance of 14.5 kilometres from the runway threshold and 1,500 metres to the right of the extended runway centreline.
Investigation and cause
Cause
The wreckage of the aircraft was found after two days. When examining the debris, the investigators found that the pitot tube heating had been switched off. Based on the circumstances of the accident, they concluded that the pitot tubes had been blocked by rain or ice formation. For this reason, incorrect values for altitude and airspeed had been transmitted to the cockpit. The crew had then let the aircraft descend to an altitude of 70 metres above the airport elevation (200 metres above sea level). At that location, however, the minimum safe altitude had been 600 metres.
