What happened
During the final approach to Rio de Janeiro-Galeão Airport, the flight crew encountered deteriorating meteorological conditions characterized by low visibility. The aircraft was on an inbound track from the southwest when it descended below the safe glide path. Consequently, the airframe impacted the terrain of a mountain slope within Tijuca National Park. The collision with the ground resulted in the destruction of the aircraft and the fatalities of all 21 people on board.
Findings
The accident occurred during the approach phase under adverse weather conditions that limited visual references. The primary contributing factor was the aircraft being at an insufficient altitude relative to the terrain, leading to a controlled flight into terrain event.
