Circumstances:
The aircraft was on a non-scheduled flight from Kalibo to Manila. It took off from runway 05 at 1740 hours Philippine local time and the co-pilot testified that the take-off was normal and all engine instruments were indicating within normal operating range throughout the take-off and during the initial climb. He further testified that approximately 20 minutes after take-off, severe vibration and misses, decreasing oil pressure and increasing oil temperature of the left-hand engine, were noted as the airplane was climbing to 2,200 feet. The left-hand engine was shut down, its propeller feathered, and shortly after the pilot-in-command reversed course and descended with the intention of landing at either Kalibo or Roxas Airports. Neither airport was rated for night operations. The flight proceeded to Kalibo. Precipitation was encountered on the way and the visibility was so poor that the crew failed to make visual contact with Kalibo Airport. At 1823 hours, a climb to 2,000 feet was attempted to clear the terrain on the way to Bacolod Airport, the nearest airport available for night operations. However, with METO power on the remaining engine, the aircraft not only failed to climb but also failed to maintain altitude with the airspeed decreasing to 80 mph. Several attempts to climb were made but were discontinued due to pre-stall warning. At 1835 hours with 500 feet altitude, the pilot-in-command decided to ditch and warned the passengers accordingly. At 1839 hours, the ditching was attempted but the airplane collided with coconut trees located approximately 500 feet from the Barrio Camansi Norte shoreline and crashed on the muddy bed of an abandoned fishpond on a heading of 300°, approximately 160 feet from the point of initial collision. The accident occurred around 1840 hours.
Probable cause:
The Board determined that the probable cause of the accident was failure to maintain safe single-engine speed and altitude following failure of the left engine. The precipitation and poor visibility prevailing at the time of the accident over Kalibo and its vicinity and the failure on the part of the maintenance personnel to take action to correct discrepancies logged in the aircraft logbook, individually or collectively contributed to the cause of the accident.

Circumstances:
Prior to his departure from Siocon Airport, the pilot was informed about the poor weather conditions enroute and at destination. Despite the visibility was below the minima, he decided to start the flight. While flying under VFR mode in heavy rain falls, the single engine airplane struck a hill and was destroyed. The wreckage was found few hours later and all 11 occupants have been killed.
Probable cause:
The pilot continued to fly VFR into unfavourable weather over the jagged shoreline with practically zero visibility due to heavy rain. At the time of the accident, the visibility was below minima.

Circumstances:
The aircraft was completing a flight from Travis AFB to Clark AFB with an intermediate stop at Hickam Field, Honolulu, carrying US soldiers and their family members. While descending to Clark AFB runway 02, the crew encountered poor weather conditions with low clouds, rain falls and a limited visibility to one mile. Five km from the runway threshold, the crew passed below the glide and the ATC in charge of the approach sent three warnings to the crew. Despite this, the pilot-in-command continued the approach and at three km from the runway threshold, the crew was instructed to go around. As the captain had the runway in sight, he neglected this order and decided to continue the approach, changed his frequency and contacted the tower when he was cleared to land. At a distance of 1,050 meters short of runway threshold, the nose gear struck a fence and the left wing struck the TACAN (Tactical Air navigation) antenna. The airplane stalled, hit the ground and slid for several yards, crossed a road where it struck a taxi and came to rest in flames 600 meters short of runway and 100 meters to the left of the extended centerline. Five crew members, among them both pilots, were injured, while all 74 passengers, five others crew members and the taxi driver were killed. Both taxi's passengers were injured as well.
Probable cause:
Wrong approach configuration on part of the flying crew who decided to continue the approach despite he was instructed by ATC to abandon the approach and to go around. Marginal weather conditions were considered as a contributing factor as well as the lack of ATC coordination as the ATC in charge of the approach instructed the crew to go around and the ATC by the Tower cleared the crew to land.

Circumstances:
The aircraft departed Malabang at 1540LT under VFR rules in good weather conditions. While overflying the Lanao Lake at an altitude of 2,300 feet, weather conditions worsened but the captain decided to continue under VFR mode. Approaching Marawi in poor visibility, the aircraft struck the slope of a mountain and disintegrated on impact. A passenger survived while 31 other occupants were killed.
Probable cause:
Pilot factor: The pilot continued to fly VFR into unfavourable weather. The weather enroute and at the destination was below VFR minima. The pilot flew at low altitude over mountainous terrain in instrument meteorological conditions. Weather factor: Low ceiling, limited visibility and rain contributed to the accident. Turbulence characterized by downdrafts or updrafts were prevalent over the mountainous area at low altitude.

Circumstances:
Flight 984 was on a scheduled domestic flight from Zamboanga to Davao, with an intermediate stop at Cotabato. It departed Cotabato at 0940 hours, with a crew of three and twenty-four passengers, estimating Davao at 1025 hours. At 1002 hours the flight reported to the Company radio station at Cotabato that it was halfway to Davao, at Flight level 60, descending. Later on, it contacted the Company radio station at Davao and requested the Davao weather. After having received weather information the flight advised that its arrival would be delayed on account of bad weather. No aircraft difficulty was reported and this was the last message from the flight. When the aircraft failed to arrive, 30 minutes after its ETA a search was started. The aircraft was subsequently found on Mt. Boca, approximately 50 miles SE of Davao Airport, where it had crashed at an altitude of 3 000 ft around 1130 hours. All 27 occupants were killed.
Probable cause:
The probable cause of the accident was due to navigational error, en-route and during let-down. Contributory factors were the limited visibility and the crosswind, all existing on the final phase of the flight.

Circumstances:
Shortly after takeoff from Manila-Intl Airport, while climbing, the airplane went out of control and crashed in the suburb of Parañaque located south of the airfield. The aircraft was destroyed and all three crew members were killed while there were no casualties on the ground. The crew was involved in a local training flight at the time of the accident.
Probable cause:
It would be inconclusive for the Board to advance any definitive cause(s) of this accident. The airplane was in emergency a few seconds before it crash-landed. It is, however, deduced that the emergency landing was in all probability attributed to the error on the part of the crew, in that the attempt to relight the left engine, presumable during the process thereof, the right engine was instead, and unintentionally taken for granted. Factors contributing to the accident were the very short time and the relatively low altitude.
