Accident
While approaching Ibiza Airport, the aircraft encountered poor visibility due to fog. The crew failed to realize their altitude was insufficient. Traveling at an excessive speed of 515 km/h, the airplane struck the slope of a hill located between Mt Rocas Altas (365 m) and Mt Atalaya de San José (301 m). The wreckage was found 8 km northwest of runway 07 threshold, approximately 30 meters below the summit. The aircraft disintegrated on impact, and all 104 occupants were killed.
Crew
The flight crew consisted of Captain José Luis Ballester Sepúlveda, Copilot Jesús Montesinos Sánchez, Flight Engineer Vicente Rodríguez Mesa, and stewards Pilar Merino López Baeza, Pilar Miravet Martín, and Manuel Fernández Cuesta.
Investigation and Probable Cause
The official investigation concluded that the accident was the result of a controlled flight into terrain due to a premature descent in limited visibility, causing the airplane to descend below the minimum descent altitude (MDA).
