Lineas Aéreas La Urraca

Shortly after takeoff from Bogotá-El Dorado Airport, while climbing, the crew encountered technical problems with an engine that lost power. Unable to maintain the prescribed altitude, the crew attempted an emergency landing in a prairie when the aircraft crashed near the suburb of La Libertad, about 9 km southwest of the airport. All three occupants escaped uninjured while the aircraft was damaged beyond repair.

When landing at Arauca (AUC) after a flight from Paz de Ariporo (PZA) and Tame (TME) a loss of hydraulic fluid was noted on the left main gear hydraulic system. A split hose was changed before the aircraft left for a flight to Cúcuta. Some 5 minutes after takeoff a burning smell and smoke were noticed in the cockpit. It appeared then that the undercarriage was still extended, though the undercarriage indicators in the cockpit didn't show this. The crew elected to divert to Villavicencio and made two low runs over the field to obtain instructions from the chief of maintenance and the airline's instructor. While on final approach to runway 22 the pilot was told by the instructor on the ground to feather the no. 1 engine as a precautionary measure. After passing the threshold at low altitude, power was reapplied and the aircraft turned slowly to the left, lost altitude and crashed in flames.

The Curtiss C-46 operated on a ferry flight from Fairbanks to Bogotá via Miami and Kingston, carrying four spare engines and spare parts. The plane arrived at Kingston on November 25, 17:01 GMT. Following refueling of the aircraft, fuel was observed venting from the right front tank. This caused a delay in departure. At 08:47 GMT the next day, the C-46 lifted off from runway 29 after a long takeoff run and was cleared to climb ahead to 1500 feet. The plane started to turn left on crossing the coastline. Three minutes after takeoff, while still in a shallow climbing left-hand turn, the aircraft flew onto the southern face of Port Henderson Hills at a height of 700 feet. After scraping along rough ground over the brow of the hill, the aircraft fell down a steep precipice and caught fire.
