Circumstances:
The crew was performing a cargo flight from Lima to Las Malvinas (Sabeti), and departed Lima-Jorge Chávez Airport at 1009LT for a 78-minutes flight. 32 minutes into the flight, while overflying the Andes mountains at FL195, the crew lost control of the airplane that crashed in a mountainous area located near Tomas. The wreckage was found the following day and all four occupants were killed while.
Probable cause:
Both engines failed in flight due to icing accumulation and inappropriate use of the deicing systems. The 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.
