Unfallbericht:
Flight 103 took off from Boston runway 33L at 14:08 in bad weather (800 m visibility in snow, fog and moderate to severe icing in precipitation).
The cargo aircraft reached an altitude of 1700 feet after takeoff and started to descend. The aircraft descended into a wooded area and crashed.

Probable Cause:

PROBABLE CAUSE: "Degraded aerodynamic performance beyond the flight capabilities of the aircraft resulting from an accumulation of ice and snow on the airframe before take-off and a further accumulation of ice when the aircraft was flown into moderate to severe icing conditions following take-off.
Contributing were encounters with windshear, downdraughts and turbulence during the climb. The failure of the flight crew to obtain an adequate pre-flight weather briefing and the failure of the National Weather Service to advise the crew of a SIGMET for severe icing conditions were also contributing factors."
