Circumstances:
While cruising under VFR mode on a flight from Quibdó to Medellín, the crew encountered marginal weather conditions with mist and intermittent rain falls. At an altitude of 11,500 feet, the airplane impacted the slope of Mt El Plateado located in the northeast part of the Chocó Province, about 66 km northeast of Quibdó. The aircraft was destroyed by impact forces and all 23 occupants were killed.
Probable cause:
The following findings were identified:
- The crew continued the flight under VFR mode in adverse weather conditions.
- The crew deviated from the airway specified in the air route manual and maintained a flight level below that established for instrument flight conditions.
- Poor supervision on part of the Operation Personnel and the Operator, by allowing crews to deviate from flight routes within the airways clearly established in the Colombian Air Routes Manual.
