What happened
During a nighttime final approach into Buenos Aires, a four-engine airplane encountered heavy fog which significantly restricted visibility for the flight crew. While attempting to land on runway 11, the aircraft descended below the required altitude and collided with trees situated approximately 2.5 km before the runway threshold. The impact caused the plane to lose altitude and crash into a wooded area located roughly 300 meters to the right of the extended centerline. A large fire broke out following the impact, resulting in the total destruction of the airframe. Among those on board, 22 occupants were injured, while 42 others escaped without harm.
Findings
Investigations into the accident determined that the crew utilized an incorrect approach configuration during the descent. The primary contributing factor was the crew's failure to follow the established approach checklist and monitor flight instruments while operating in reduced visibility. This lack of procedural compliance led to the aircraft maintaining an altitude that was too low for a safe approach.
