Narrative:
GAF Nomad ZP-TDZ was chartered for some flights in northern Argentina. It left Asunción (ASU) for Resistencia Airport, CH (RES). After another landing at Joaquín V. González, the aircraft continued to Salta (SLA). During the descent both engines flamed out as a result of icing of the air intake. The pilots had to carry out a forced landing near the Ruta Provincial 24. The Nomad struck some trees and landed in a plowed field. The undercarriage was completely destroyed.

CAUSE:
During a non-scheduled commercial flight, in the final approach phase, a landing was made on an unprepared field, due to the failure of both engines because of incorrect use of aircraft anti-icing system, resulting in significant damage but no injuries to the people aboard.
Contributing factors:
1) Poor flight planning.
2) Conditions favorable for the formation of ice.
