What happened
During the flight, the weather environment deteriorated significantly due to the onset of rain showers and a lowering cloud ceiling. In response to these changing conditions, the crew made the decision to abort the current mission and return to the point of departure. However, during this diversion, the aircraft drifted away from its intended flight path.
While the crew was operating the aircraft under visual flight rules (VFR) despite being inside instrument meteorological conditions (IMC), the plane impacted a mountain slope. The collision caused the aircraft to burst into flames upon impact. There were three fatalities among the occupants of the aircraft.
Findings
Investigations into the accident determined that the primary factor was the decision to maintain VFR flight procedures while flying through IMC conditions, which led to the controlled flight into terrain.
