Investigation Summary
The flight was a multi-leg domestic service from São Paulo to Fortaleza with a stopover in Rio de Janeiro. During the final leg, as the aircraft approached Fortaleza at night, the crew received clearance to descend to 5,000 feet. The captain, Fernando Antônio Vieira de Paiva, appears to have become visually fixated on the bright lights of the city of Fortaleza. This visual distraction, combined with a possible lack of situational awareness regarding the local topography, led him to continue the descent past the assigned altitude. The Cockpit Voice Recorder (CVR) captured the co-pilot questioning the descent and the Ground Proximity Warning System (GPWS) sounding multiple alerts, all of which were ignored by the captain. The aircraft impacted the Aratanha Mountains at approximately 2,500 feet, roughly 30 kilometers from the airport.
Final Conclusions
The investigation concluded the primary cause was Controlled Flight Into Terrain (CFIT) resulting from pilot error. The captain failed to adhere to the altitude clearance limit and ignored both the co-pilot's verbal warnings and the automated GPWS alerts. Contributing factors included visual illusions caused by city lights in a night environment and poor cockpit resource management, as the first officer failed to take control of the aircraft despite recognizing the danger.
