What happened
A cargo operation traveling from Salta to Córdoba, which included a scheduled stop in San Miguel de Tucumán, ended in a fatal accident. The flight was transporting two pilots and one passenger at the time of the incident.
While proceeding toward its destination, the crew received clearance to descend to 8,000 feet before being cleared for an ILS approach to runway 18. During the approach, which was conducted under night conditions and within Instrument Meteorological Conditions (IMC), the aircraft descended below the minimum descent altitude (MDA). The aircraft type struck an open field approximately 11.4 km from the threshold of the runway. The impact resulted in the total destruction of the airframe and three fatalities.
Findings
The investigation determined that the crew failed to successfully intercept the ILS signal for runway 18. Due to this failure, the descent continued past the permitted altitude limits, leading to the impact with terrain below the MDA.
