Although the pilot filed an IFR flight plan through the Direct User Access Terminal System (DUATS),” said the NTSB, “no evidence of a weather briefing was found.” The Safety Board determined the probable cause(s) of this accident to be:

The airplane's encounter with unforecasted severe icing conditions that were characterized by high ice accretion rates and the pilot's failure to use his command authority to depart the icing conditions in an expeditious manner, which resulted in a loss of airplane control.

We have become a generation of self-briefers. Near-real-time weather is available online and from ATC and pilots aloft. However, we have to look for it electronically or ask for it. Investigators are beginning to see more accidents involving incomplete self-briefing.

Ice can always be a killer. Any mention of ice should start pilots thinking about ice avoidance. As the SIMCOM instructor said, “. . . the installed ice protection systems are intended to provide protection while departing icing conditions.”

When your aircraft is accumulating ice, you need to be somewhere else quickly. That could mean declaring an emergency to get immediate relief. It's always better to deal with the ATC paperwork after you land safely than burden NTSB personnel with the paperwork that goes with an accident investigation.
