Incident Overview
An aircraft experienced a crash landing after the pilot encountered severe structural icing conditions during flight. The pilot had been briefed on enroute weather prior to departure, and records indicate that SIGMETs for icing and turbulence along the route were provided. Despite this information, when the pilot encountered icing conditions in flight, he continued on the route instead of turning back to non-icing conditions.
Weather Briefing
According to available records, the pilot received a weather briefing that included SIGMETs warning of icing and turbulence along the intended route. The specific nature and extent of the briefing were detailed in the documentation.
Flight Progress
During the flight, the aircraft entered conditions conducive to icing. Structural ice accumulated very rapidly on the airframe. At some point, the pilot requested and received vectors to fly to the nearest airport. During the descent, the pilot reported that more ice accumulated, and he was unable to see through the windshield due to ice coverage.
Accident
The pilot attempted a landing but made a crash landing across the runway. The aircraft came to rest in a location that was not on the runway surface.
Witness Observations
Witnesses at the scene reported that the aircraft wreckage exhibited a thick covering of structural ice after the accident. This observation corroborated the pilot's report of icing conditions during flight.
