Circumstances:
Just after liftoff from runway 03, while in initial climb, the captain informed ATC about the failure of the left engine. He received the permission to return for an emergency landing but the airplane stalled, banked left and crashed in a huge explosion about 4 km from the airfield. Both pilots and 26 passengers were killed while nine other occupants were injured.
Probable cause:
The accident was caused by the malfunctioning of the left engine shortly after take-off but after V2 (the takeoff safety speed). Contributing factors were:
- The darkness of the night which limited the visibility of the pilot during the emergency,
- The inappropriate emergency procedure(s) carried out, or resorted to by the pilot.

Circumstances:
While flying in poor weather conditions on a flight from Iloilo City to Manila, the airplane struck the slope of Mt Baco located in the occidental Mindoro province. The wreckage was found a week later, on the east slope of the mountain, at an altitude of 1,829 meters. All 33 occupants were killed in the crash. At the time of the accident, the airplane was off course by 51 km and weather conditions were poor with thunderstorm activity.
Probable cause:
The probable cause of the accident was a navigational error. Contributing factors were: adverse weather conditions and poor visibility, a 25-35 knot crosswind coming from the east, unreliability of the airborne navigational equipment due to either atmospheric disturbance night and terrain effects and/or its possible malfunctioning.

Circumstances:
While descending to Zamboanga City Airport, weather conditions deteriorated and the crew was instructed by ATC to divert to Davao City located 400 km east to their actual position.

All 31 occupants were quickly rescued while the aircraft sank and was lost.
Probable cause:
It was determined that both engines failed due to fuel exhaustion.

Circumstances:
The aircraft was on a scheduled flight from San Francisco, California to Singapore with numerous intermediate stops including Manila, The Philippines. It carried a crew of 8 and 49 passengers including one infant. At 21 23 hours (1 June) GMT the aircraft landed on Runway 06 at Manila. During the landing roll, the main landing gears of the aircraft collapsed. The aircraft skidded and swerved to the right until it finally settled on the right shoulder of the runway approximately 2 850 ft from the west end and 27 ft from the edge of the runway. One of the blades of No. 3 propeller flew off and penetrated the cabin area causing the death of one passenger and seriously injuring another. The aircraft was seriously damaged.
Probable cause:
The hard landing of the aircraft caused the failure or collapse of the right main gear 'V' strut support. Contributing factors were the heavy rains and gusty wind.

Captain / Total flying hours:

Circumstances:
PI-C626 departed Manila on a non-scheduled flight to Cebu and return with intermediate stops at Marinduque, Iloilo and Bacolod. The flight as far as Bacolod was uneventful. However, shortly after taking-off from Bacolod at 1210LT, and on reaching the height of 5 to 8 ft from the ground, the aircraft banked to the left. The pilot tried to correct the attitude of the aircraft but was unsuccessful. He, therefore decided to crash land the aircraft. There were no fatalities but the pilot and some passengers suffered minor injuries. Fire broke out on impact which destroyed the main front section of the aircraft.
Probable cause:
The captain prematurely "lifted" the aircraft before attaining the V2 speed. A contributing factor could have teen the presence of the 25 to 30 mph crosswind.

Circumstances:
At approximately 1310 hours PI-C55 took off from Ozamis City Airport for Pagadian on a scheduled flight with a pilot, nine passengers and two infants on board. Following a normal take-off and climb, the aircraft, at an altitude of 75 ft, was seen on a steep climb followed by a steep turn to the left. It then suddenly lost altitude, hit two trees and crashed in a nose-down attitude. Fire broke out immediately. The pilot and one passenger were killed, all 10 other occupants were injured.
Probable cause:
The probable cause of the accident was the uncontrollable stall at low altitude which resulted from the abrupt steep climb immediately after take-off. Contributing factors were:
- The improper loading of the aircraft,
- The prevailing gusty wind with a relatively high ambient temperature.

Circumstances:
At approximately 0540LT, PI-C622, with 5 passengers and a pilot aboard took off from the Manila International Airport on a charter flight to Ozamis City and return. The aircraft departed Ozamis on the return trip to Manila at approximately 1550LT the same day. At approximately 1830LT, radio contact with the Manila Tower was established and the aircraft reported its position to be over the Province of Batangas, which is about 60 nautical miles SW of Manila and lies on course on the route Ozamis-Manila. On the C-45F Beechcraft it takes about 25 minutes flight time to Manila. The pilot requested information as to the prevailing weather conditions over Manila and vicinity and the weather report as of 1800LT was relayed to and received by the pilot. Further efforts were made by the Tower at 1900LT and 1930LT to contact the aircraft but with negative results. At approximately 2030LT, the Manila Tower received the information from the Rescue Coordinating Centre that the aircraft crashed in a wooded area located on Mt Makiling, in the region of Tanauan, about 45 miles SW of Manila. The aircraft was totally destroyed and all six occupants were killed, among them Carlos P. Romulo, son of the US Ambassador in the Philippines. The pilot founded PADC in 1954.
Crew:
Paul L. Gunn, pilot.
Passengers:
Carlos P. Romulo,
Allen O. Gorman,
Raplh L. Tover,
Zane Duncan,
Harold Broad.
Probable cause:
The Board determined that the probable cause of the accident was the unsuccessful procedure of the pilot in trying to avoid the severe thunderstorm existing over the area at that time. His attempt to fly below the thunderstorm resulted in a ground collision. A contributing factor was the weather over the area which, at the time of the accident, was zero visibility and almost zero ceiling, with a high degree of turbulence, heavy rain and lightning. Also, the Board concluded that even if the right engine of PI-C-622 was feathered at such 1,500-foot altitude over the vicinity of the crash, the aircraft could still have climbed. From evidence gathered by the Board, there was no factual finding either on the airframe or on the engine maintenance that might have contributed to the crash. The Board was more inclined to attach the circumstances surrounding the accident to the weather in that the pilot in all probability flew low to 'get under the overcast'
