Circumstances:
Crew was performing a cargo flight from Lima to Malvinas, east part of Peru, and left Lima-Jorge Chavez Airport at 1009LT for a 78 minutes flight. After 32 minutes into the mission, while overflying Andes mountains at FL195, aircraft disappeared from radar screens and crashed in a mountainous region near Tomas. SAR arrived on scene one day later and all four occupants were killed while the aircraft was destroyed by impact forces.
Causes:
Both engines failed in flight due to icing accumulation and incorrect use of deicing systems.
Following factors were considered as contributory:
Poor flight planning on part of the crew,
Poor crew resources management,
Poor crew simulator training (icing detection and dual engine failure),
Lack of procedures relating to icing conditions and dual engine failure,
Marginal weather conditions which contributed to ice accumulation on engines and airframe.
Final Report:
