Weather Briefing
The pilot, holding an Airline Transport Pilot (ATP) rating, obtained a complete weather briefing prior to departure. The briefing included forecasts of occasional moderate icing, a Cleveland Center weather advisory, winds aloft with temperatures at the planned flight altitude of 6,000 feet ranging from -1 to -4 degrees Celsius, and pilot reports (PIREPs) of moderate icing from 5,000 to 11,000 feet. One PIREP indicated moderate to severe icing at 5,000 feet.
Departure and Communications
The aircraft was not equipped with deice or anti-ice systems. After departure, within three and a half minutes, the pilot began requesting altitude diversions. Communications between the pilot and air traffic control, along with radar data, showed that the pilot was unable to maintain altitude.
Accident
The aircraft subsequently crashed and burned in a mountainous area. No further information on injuries, fatalities, or aircraft details was provided in the source.
