Circumstances:
The crew departed San José Airport in the early morning on a cargo flight to Upala. About 20 minutes after takeoff, while cruising at an altitude of 4,700 feet in clouds, the airplane struck the slope of the Arenal volcano. The airplane was destroyed and both pilots were killed.
Probable cause:
It was determined that the airplane was slightly off course at the time of the accident due to a northeast wind. The crew was unable to distinguish the mountain that was shrouded in clouds (stratus). Also, the crew started the descent to Upala a bit too early, which was considered as a contributing factor.
