Circumstances:
The twin engine aircraft departed Valera Airport on a charter flight to San Antonio del Táchira with an intermediate stop in El Vigía, carrying five passengers and one pilot. All flight was completed under VFR mode but while descending to San Antonio del Táchira, weather conditions worsened and the pilot switched to IFR mode. Shortly later, control was lost and the aircraft crashed on the slope of Mt Laja, near Lobatera. The wreckage was found about 25 km northeast of San Antonio del Táchira Airport. The aircraft disintegrated on impact and all six occupants were killed.
Probable cause:
The most probable cause for the occurrence of this accident was the loss of situational awareness, caused mainly by the change of flight conditions under visual rules to flight under instrumental flight rules, due to the adverse weather conditions in which the descent phase began, so it is possible to establish the Human Factor as the cause of the accident and the Physical Factor as a contributor.

Aircraft flight hours:

Circumstances:
The aircraft departed San Antonio del Tachira Airport at 1230LT for a 2 hours and 45 minutes flight to Maiquetía-Simon Bolivar Airport. En route, while cruising in poor weather conditions, the airplane struck the slope of a mountain located near Páramo de Turmal. The wreckage was found few hours later and all 12 occupants have been killed. At the time of the accident, the airplane was not following the assigned route due to navigation error on part of the crew.
Probable cause:
A navigational error in course of an instrument flight at insufficient altitude caused the accident. Contributing factors were:
- Failure to follow the route San Antonio - Maiquetía as called for by the LAV Operations Manual,
- The flight took place outside of the route established by the National Airways Division,
- Overconfidence of the pilot in his knowledge of the route,
- Instrument flight which prevented visual checking of the position of the aircraft.
