What happened
While operating en route, the crew encountered adverse meteorological conditions characterized by snow showers. During this period, visibility decreased to approximately two miles. While flying through these reduced visibility conditions, the pilot-in-command lost control of the aircraft, which subsequently entered a dive and struck an open field. The impact resulted in a large explosion that completely destroyed the airframe.
There were six fatalities recorded in the accident, with no survivors among the occupants.
Findings
Investigation into the crash determined that the primary factor was that the crew failed to maintain the necessary flying speed during the encounter with the weather.
