Sequence of events
At 03:32 UTC, Flight 331 took off from Lisbon Airport and climbed to 35,000 feet (11,000 m). While on approach to Havana, the crew reported seeing false altitude and air pressure readings. They were then granted permission to descend from 35,000 to 15,000 feet (10,700 to 4,600 m), followed by a descent to 3,000 feet (910 m). At the time, cumulus clouds were present, visibility was 8 kilometres (5.0 mi; 4.3 nmi) with a dense fog at 40 metres (130 ft), atmospheric pressure was 758 mmHg (0.997 atm), and the temperature was 21 °C (70 °F). At 8:45:28 (12:45:28 UTC) local time, still 1,270 metres (1.27 km; 0.79 mi) from the runway, the crew spotted four power lines 28-metre (92 ft) high, and attempted to avoid them by pitching the nose up. However, at 23–25 metres (75–82 ft), they clipped all four lines, slicing the stabilizer and severing the right outboard wing flaps. The damage caused the aircraft to making a sharp 70° bank to the right over the next three seconds. The aircraft then struck the ground with its right wing and nose and caught fire, destroying it. Only the tail section remained.
The only two survivors of the crash were a West German woman and a Soviet man. One of the victims was José Carlos Schwarz, a poet and musician from Guinea-Bissau.
Investigation
An investigation revealed serious errors made by the crew in the last moments of the flight. The main cause of the accident was a blatant violation of approach procedure, errors in calculating altitude that resulted in incorrect altitude readings that led to a premature descent, and the crew's attempt at a visual approach in dense fog. Also cited was the incorrect use of the radio altimeter by the crew.
