Accident Overview
A twin-engine aircraft departed from San José–Tobías Bolaños Airport under relatively good weather conditions. During its climb to an altitude of 6,000 feet, the aircraft collided with the slope of White Peak (Cerro Blanco), a mountain 2,438 meters high located approximately 20 kilometers southeast of the airport. The wreckage came to rest about 600 meters from the summit. All 23 occupants on board were killed.
Weather and Conditions
At the time of the accident, visibility was reported as good. However, some atmospheric turbulence was noted in the vicinity of the mountains.
Official Findings
The probable cause of the accident was determined to be loss of control resulting from atmospheric turbulence. The investigation also identified contributing factors: the crew was fatigued, and the operator had failed to implement a valid flight safety program.
