Circumstances:
The aircraft took off from Tenerife airport at 0821. After two minutes of flight the propeller of the left engine began overspeeding. The pilot-in-command applied the normal overspeed procedures, but obtained no response to the manoeuvre. He then actuated the feathering mechanism but this also was ineffective and as the aircraft was losing height he was obliged to ditch it approximately one mile from the coast, since the orography of the locality made a landing impossible. The ditching took place normally. The aircraft remained afloat approximately five minutes and then sank carrying with it one of the passengers who refused to abandon it and who had impeded the evacuation of the other passengers and resisted the efforts of the pilot-in-command and hostess to get him to safety.
Probable cause:
The accident resulted as a consequence of propeller overspeed on the left side, the cause of which could not be determined owing to the fact that the aircraft was not recovered.

Circumstances:
Shortly after takeoff from Al Azaiba Airport, the airplane encountered difficulties to gain height. It struck trees, stalled and crashed 500 meters past the runway end. All 20 occupants were rescued while the aircraft was damaged beyond repair.
Probable cause:
Loss of engine power due to the carburetor air intake shutters had been selected to 'Hot air' instead of 'Ram air'. On other C-47 aircraft operated by Gulf Air, the air intake control levers were positioned the other way around.

Circumstances:
The aircraft was set off for a surveillance mission around the Pathet Lao stronghold of Sam Neua. During the mission the aircraft flew close to (and may even have crossed) the border into North Vietnam. MiGs had occasionally been seen operating close to the Laotian border but it was thought that they posed little threat to aircraft operating in the Sam Neua area. However, a MiG-17 made a high speed dash to the border and shot down the RC-47D before making off deep into North Vietnam. All eight crew members were killed:

Probable cause:
Shot down by the pilot of a North Vietnam Air Force MiG-17.

Circumstances:
Flight 785 was a scheduled domestic VFR flight from Manila to San Jose with an intermediate stop at Mamburao. The aircraft departed Manila at 1030 hours local time and arrived at Mamburao after an uneventful flight. It then took off from Mamburao at 1204 hours. At 1215 hours, the flight requested terminal weather information from San Jose Radio Station. The requested information was transmitted but was not acknowledged. A witness stated that at approximately that same time he had observed an aircraft flying at very low altitude towards the mountain on a heading of approximately 065° and that, soon after, the aircraft disappeared from sight, he heard a loud explosion coming from the mountains east of his position. Subsequent efforts of San Jose Radio Station to contact the flight on both VHF and HF frequencies proved unsuccessful. In the afternoon of 1 July 1966 the wreckage of the aircraft was found at 2,300 feet AMSL in a ravine at the northern slope of Mt Rabangan (altitude 3,500 feet) which is approximately midway between Mamburao and San Jos6 and approximately 10 nautical miles inland. Two passengers were seriously injured while 26 other occupants were killed.
Probable cause:
The Board determined that the probable cause of the accident was misjudgement of the terrain clearance which resulted in the collision with trees. The instrument meteorological conditions en-route accompanied by severe turbulence and strong gusty winds over the crash site were a contributory factor. The weather and the sky condition at the time the airplane as seen over Sablayan was described as low thick dark clouds with strong wind and heavy rain. The actual weather in the vicinity of the crash site was substantially similar to the weather forecast that was conveyed to the pilot by the dispatcher during the weather briefing prior to the flight. Thirteen minutes after take-off the pilot encountered instrument meteorological conditions en-route under a VFR flight clearance.
