Curtiss C-46 Commando

Everts Air Cargo

The pilot reported that, following a precautionary shutdown of the No. 2 engine, he diverted to an alternate airport that was closer than the original destination. During the landing in tailwind conditions, the airplane touched down "a little fast." The pilot added that, as the brakes faded from continuous use, the airplane was unable to stop, and it overran the end of the runway, which resulted in substantial damage to the fuselage. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Buffalo Airways

The Buffalo Airways Curtiss C-46A (C-GTXW) was operating as flight 525 from Yellowknife, NT (YZF) to Norman Wells, NT (YVQ). While en route, approximately 140 nautical miles southeast of Norman Wells at 6500 feet above sea level, the crew noticed a drop in the right engine oil quantity indicator in conjunction with a propeller overspeed. The propeller pitch was adjusted to control the overspeed however, oil quantity indication continued to drop rapidly. A visual confirmation of the right engine nacelle confirmed that oil was escaping via the engine breather vent at an abnormally high rate. The right propeller speed became uncontrollable and the crew completed the "Prop overspeed drill". However, the propeller did not feather as selected. Several additional attempts were made to feather the propeller before it eventually feathered. The engine was secured and the shutdown checklist completed. The crew elected to divert to Tulita, NT (ZFN), but quickly determined that the descent rate would not permit that as an option. The only other option for diversion was Déline, NT (YWJ) where weather was reported at half a mile visibility and 300 feet ceiling. An emergency was declared with Déline radio. BFL525 was able to land at Déline however, the landing gear was not selected down to prevent further loss of airspeed resulting in a belly landing approximately midpoint of runway 08. The aircraft continued off the end of the runway coming to a stop approximately 700 feet beyond the threshold. The crew evacuated the aircraft sustaining no injuries however, the aircraft was destroyed.

The crew departed Santa Cruz-Viru Viru Airport at 0807LT on a cargo flight to Cobija-E. Beltram Airport. Shortly after takeoff from runway 16, the crew informed ATC he was returning but did not give any details about his situation. On final approach, the aircraft adopted a high-nose attitude, climbed then stalled and crashed 200 metres short of runway, bursting into flames. The passenger was seriously injured and all three crew members were killed. The aircraft was totally destroyed by a post crash fire.

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.

Rolando Medina Marmolejo

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.

Transportes Aéreos Virgen del Carmen

While on a cargo flight, the crew encountered technical problems and was forced to attempt an emergency landing somewhere in east Bolivia. The aircraft crash landed and came to rest in trees, broken in two. There were no casualties. The exact date of the accident remains unknown, somewhere in 1997.

Private American

The aircraft was probably involved in an illegal flight when it crashed and burnt while trying to land in a remote area located near Huetamo de Núñez. No one was found in the wreckage and it was later confirmed that the registration N1442V was false.

Cooperativa Interregional de Colombia

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.

Líneas Aéreas Suramericanas

Upon landing at Puerto Inírida Airport, the undercarriage collapsed. The aircraft came to rest in its belly and was damaged beyond repair. All three crew members escaped uninjured.

Frigorifico Santa Rita

Shortly after takeoff from San Borja-Capitán Germán Quiroga Guardia Airport, while in initial climb, the left engine caught fire. The crew shut down the engine and feathered its propeller but was unable to extinguish the fire. Unable to return, the crew attempted an emergency landing in a field located near Aurora. The aircraft came to rest, bursting into flames. All three crew members escaped uninjured.
