Accident
A four-engine aircraft, cruising at an altitude of 8,000 feet, struck the slope of Mount Tabeyoc (9,322 feet high) located about 150 km north of Clark AFB. At the time of the accident, visibility was reduced due to clouds in the area, and the crew was unable to distinguish the mountain.
Wreckage and Casualties
The wreckage was found two days later in an isolated area. All 38 occupants were killed.
Probable Cause
The crew was flying under instrument flight rules when the accident occurred, and no mechanical failure was reported on the aircraft. The accident was considered a controlled flight into terrain.
