Circumstances:
Christened 'Mount Pinatubo', the airplane departed Cebu City past 0130LT bound for the capital city, carrying journalist, members of the government and Ramon Magsaysay, President of the Republic of The Philippines. While climbing by night, the right engine lost power then failed. The crew was unable to maintain a safe altitude when the airplane struck the slope of Mt Manunggal located about 35 km northwest of the Airport. Rescuers arrived on the scene in the early morning and a passenger, a journalist of the 'Philippine Herald' was seriously injured and evacuated while 25 other occupants were killed.
Probable cause:
The accident was the consequence of the failure of the spindle drive shaft on the carburetor that snapped during climb, causing the right engine to fail.

Probable cause:
Investigations were unable to determine the exact cause of the accident. Nevertheless, investigators pinpointed the following findings:
- The captain was distracted while the first officer was looking for different radio frequencies,
- Apparent failure of some instruments,
- A sudden power loss on two engines on the same side of the plane, #1 & 2 or # 3 & 4,
- Engagement of the autopilot system by a person not entitled to do so, apparently by a person other than the two pilots,
- A lateral loss of control as a result of the malfunction of flaps that have been deployed in an asymmetric position,
- Technical issue on the primary control system,
- A structural failure that probably occurred on the extremity of both wings and on the tail simultaneously.
