Circumstances:
The flight crew was returning from off-loading their cargo at a remote site on the west side of a mountain range. The return flight would provide an option of following a lower mountain pass, or flying over the mountainous terrain. Witnesses related that prior to the flight's departure, the marginal VFR weather conditions began to deteriorate very rapidly, with winds in excess of 50 knots, lowering ceilings, rain, and turbulence. An airmet, valid during the time of the accident, forecast high winds, mountain obscuration, and turbulence. The wreckage of the airplane was located near the crest of a 2,900 feet msl ridge. Wreckage debris was scattered on both sides of the ridge, and the airplane was destroyed by the high speed impact. Inspection of the wreckage disclosed no evidence any mechanical anomalies. A radar track analysis of a target airplane believed to be the accident airplane, depicted a track on a direct route of flight over the mountains from the departure airport towards the destination airport. Altitude data was not received from the target airplane's Mode C transponder, and therefore was extrapolated from the less reliable radar plot information. The maximum altitude plotted was approximately 10,800 feet, prior to a descent as the airplane neared the west side of the range. Mountains along the route of flight exceed 10,000 feet msl.
Probable cause:
The flight crew's decision to continue VFR flight into instrument meteorological conditions. Factors associated with the accident are high winds, turbulence, and low ceilings.
Final Report:

Crash of a Curtiss C-46A-60-CS Commando in Villavicencio: 10 killed

Circumstances:
The aircraft, registered to a private individual, departed Villavicencio-La Vanguardia Airport on a charter flight to Mitú, carrying 17 passengers and two pilots while the aircraft was certified to carry 13 passengers maximum. The crew filed an flight plan with only six people on board. Shortly after takeoff, while in initial climb, the right engine caught fire. The crew activated the fire extinguishing system but as both bottles were empty, the fire could not be contained. The captain initiated a right hand turn to return to the airport when the aircraft stalled and crashed, bursting into flames, two minutes after takeoff. Both pilots and eight passengers were killed while nine other people were injured. The aircraft was totally destroyed by impact forces and a post crash fire.
Probable cause:
The decision and inappropriate operation of the pilot to return with a right hand turn with an uncontrolled fire in the n°2 engine leading to a loss of lift on the wing on that side and a loss of control over the aircraft. It was also determined that the aircraft was not airworthy at the time of the accident. The crew flying experience could not be determined as the crew failed to complete their personal logbook. Also, the captain's medical certificate was not valid anymore.

Circumstances:
On approach to Villavicencio-La Vanguardia Airport runway 04, the crew encountered poor weather conditions (heavy rain falls) and a visibility limited to 1,000 metres. After passing the missed approach point, the crew was unable to establish a visual contact with the runway and initiated a go-around procedure. Shortly later, the aircraft struck the slope of a mountain located in the San Jeronimo Mountain Range, about 5 km north of runway 22 threshold. The aircraft disintegrated on impact and all 9 occupants were killed.
Probable cause:
Loss of situational awareness on part of the crew after he deviated from the standard approach procedures. The lack of visibility was considered as a contributing factor.
