As the aircraft was cruising, the left engine suffered a failure, which disabled the oil system in that engine. The crew then radioed in a mayday and diverted to La Rinconada, a plantation. While they were descending, the crew could not feather the engine which was required in an engine failure, thus they began to lose speed as the engine windmilled, creating drag. At 10:31 am local time, the crew made their final transmission stating they had the runway in sight. Ground witnesses in the area said they saw the aircraft doing several turns while descending. The aircraft then crashed in proximity to a road, coming to rest just over the road, on fire. Plantation workers rushed to help, but they found no survivors.
