An aircraft struck a hillside slope during final approach to San José Airport, resulting in the destruction of the airframe and the deaths of all 23 people on board.

What happened

During the final approach phase toward San José Airport, the aircraft descended at an altitude that was insufficient for safe clearance. The airframe impacted the slope of a hill located a few kilometers short of the runway threshold. This collision resulted in the total destruction of the aircraft. All 23 occupants aboard, including the pilot and co-pilot, were killed in the incident.

Findings

The primary factor contributing to the accident was the aircraft being too low during its final approach. The terrain profile required a higher descent path than what was maintained by the crew, leading to the controlled flight into terrain.

Probable cause

The aircraft was at an insufficient altitude during final approach, causing it to strike the hillside slope short of the runway.
