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.

In low visibility, the airplane struck a snow covered mountain located 12 km from the runway threshold. The aircraft was destroyed and all three crew members were killed.
Probable cause:
The probable cause was the fact that the aircraft got below the prescribed altitude limits as a consequence of having deviated from the instrument flight rules.

Circumstances:
The flight took off from Rosario at 09:01 for a flight to Buenos Aires, the last leg of a flight from Santa Fe to Buenos Aires. Flight plan altitude was 1200 m. Turbulence, however, forced the crew to climb to 1800 m and later to 2400 m. At 09:43 the pilot reported a localized fire in the cabin and reported that they intended to make an emergency landing at Zárate. The plane didn't make it to Zárate and was seen trying to make an emergency landing in a field, 9 km from Zárate. The plane struck the ground with the undercarriage, left wing and engine and started to disintegrate. A fire erupted, but didn't spread over the entire aircraft. A passenger was seriously injured while 30 other occupants were killed.
Probable cause:
Impact with the ground, for reasons which could not be ascertained, during a precautionary landing. There were fumes or smoke in the cabin and No.2 engine was cut and its propeller was windmilling, due to oil leakage.

Circumstances:
The aircraft was on a non-scheduled flight from Moosonee to Nemiscan Settlement. The pilot stated that he used the rear fuel tanks for takeoff and cruise and that they contained about 150 gallons of fuel, with about 10-15 gallons in each of the front tanks. The power settings used for the flight were about 28 inches manifold pressure and 2050 rpm with automatic lean mixture. About 50 minutes after takeoff the left engine fuel pressure dropped to zero, and the engine failed. The booster pumps were switched on and the tank selections were changed without effect. At this time the right engine fuel pressure dropped to zero, and the engine failed. Attempts to re-start were unsuccessful and when the aircraft was 200 ft above the ground the pilot realized he could not reach the Rupert River. A forced landing was made into trees about 1000 ft from the river with the undercarriage down. Both pilots were severely injured.
Examination of the wreckage showed that the front fuel tanks were empty and no fuel had apparently been used from either of the rear tanks.
Probable cause:
Engine failure due to fuel exhaustion.

Circumstances:
A Purdue Aeronautics Corporation, Douglas DC-3, N386T crashed while making an instrument approach to the Morgantown Municipal Airport, Morgantown, West Virginia. The accident occurred 2.5 nautical miles from the Morgantown VOR on the 340 degrees radial at 1110 c.s.t. 1 November 29, 1963. The stewardess was fatally injured in the accident but the captain and first officer escaped with minor injuries. There were no other persons aboard the aircraft. The aircraft was damaged beyond repair by the impact and post impact fire. N386T was being ferried to Morgantown in preparation for a charter flight.
Probable cause:
The Board determines that the probable cause of this accident was the pilot's execution of an instrument approach in an aircraft not equipped with navigational instrumentation appropriate to the ground facilities being used.
