Olympic Airways — Flight 954

Olympic Airways Flight 954, a Douglas DC-6B, crashed into Mount Paneio during an instrument approach to Athens in poor weather. The aircraft struck the mountain at approximately 2,000 feet with its landing gear still retracted, killing all 90 people on board. Investigators determined the crew had deviated from the prescribed approach track and descended below the minimum safe altitude.

Investigation Summary

Flight 954 was a domestic scheduled service from Crete to Athens. During the approach to Athens-Ellinikon International Airport, the region was experiencing heavy rain and high winds. Despite the poor visibility and weather conditions, the crew attempted an ILS approach. During this procedure, the aircraft strayed from the intended flight path and descended prematurely. The Douglas DC-6B, named 'Isle of Corfu', impacted the slopes of Mount Paneio near Keratea. The impact occurred at an altitude of roughly 2,000 feet. At the time, it was the deadliest aviation disaster in Greek history, a record that stood until the Helios Airways crash in 2005. It remains the deadliest accident involving the Douglas DC-6 airframe.

Final Conclusions

The official investigation concluded that the primary cause was the flight crew's failure to maintain the proper track and altitude. By descending below the minimum safe altitude (MSA) while off-course during the approach, the crew inadvertently flew the aircraft into terrain. The adverse weather conditions, including rain and wind, likely contributed to the crew's navigational difficulties.
