[1][2] The aircraft was a Douglas DC-3 manufactured in the United States during World War II and purchased by Philippine Air Lines in 1946.

He was qualified on the Manila-Iloilo-Manila route as captain in May 1954, and his medical record required that he had to wear corrective lenses while exercising his pilot's license.

The throttles appeared to be on the normal cruise setting, except that both mixture control levers were found to be halfway between the auto-lean and the idle cutoff position.

The pilots were expected to follow an airway "Amber-I" which was a straight line above Romblon however it was found that the aircraft had deviated around 30 miles from the initial flight path.

[5] After the crash, relatives of deceased passengers filed lawsuits against Philippine Air Lines for moral damages, income losses and legal fees.
