Investigation Summary
The flight was operating a routine domestic route from Rome to Palermo, carrying many passengers returning to Sicily for national elections. The approach to Palermo Punta Raisi Airport was notoriously difficult due to the proximity of high terrain. During the descent, the crew reported passing the PRS NDB at 5,000 feet and stated they would report downwind for runway 25 Left. However, the aircraft deviated from the prescribed approach path, heading directly toward the 3,000 foot peaks south of the airport. At approximately 22:24 local time, the DC-8 struck the crest of Montagna Longa at an elevation of 1,980 feet, roughly 300 feet below the summit. The impact was catastrophic, and the wreckage was scattered over a 2.5-mile area. The official inquiry concluded the pilots failed to adhere to the established approach procedures in limited visibility, resulting in Controlled Flight Into Terrain (CFIT). However, this conclusion has been contested for decades. Witnesses in the towns of Carini and Cinisi reported seeing the aircraft on fire before it struck the mountain. Furthermore, an independent investigation led by Giuseppe Casarubea, whose father died in the crash, suggested the aircraft may have been the victim of a bombing or sabotage linked to the 'Strategy of Tension' during the 1972 Italian general elections.
Final Conclusions
The official investigation determined the primary cause was the crew's failure to follow the established approach vectors and altitudes, leading to a collision with terrain while the aircraft was under control. The board noted that the crew had approximately three miles of visibility but did not maintain adequate situational awareness regarding their position relative to the mountains. Despite the official CFIT ruling, an independent investigation later suggested the possibility of an onboard explosion, though this was never formally adopted by the state aviation authorities.
