What happened
During a scheduled cargo operation traveling from Mendoza to Córdoba, the flight crew encountered deteriorating meteorological conditions. Specifically, low visibility caused by fog impacted the flight path. The aircraft subsequently lost control and impacted hilly terrain situated approximately 32 km north of San Luis. Upon impact, the airframe burst into flames. All three occupants were killed in the accident. The aircraft, identified as 'Santa Elena', was destroyed by the combination of impact forces and the subsequent post-crash fire.
