Accident Details
On final approach to Posadas-Libertador General José de San Martín Airport, the aircraft encountered heavy fog with visibility reported at 100 meters. The crew passed the decision height and continued the approach without establishing visual contact with the runway. The aircraft struck the tops of eucalyptus trees and crashed in a dense wooded area located 3 kilometers short of runway 01. Upon impact, the aircraft burst into flames and was totally destroyed. All 22 occupants were killed.
Probable Cause
The official investigation determined the probable cause to be the crew's decision to continue the approach in weather conditions below minimums, causing the aircraft to descend below the decision height without visual contact with the runway. Contributing factors included a poorly planned approach, lack of crew coordination, and lack of visibility.
