This quote missed an important aspect of icing violations though.
A validated forecast, by definition, means that icing is being observed, i.e.
During landing, they lost control due to icing and substantially damaged the aircraft.
So icing myth #2, that power overcomes ice, does not hold up if the pilot is unable to escape to an area where ice is shed for descent and landing.
The third myth to explore is that FAA-approved "known" icing certification makes the airplane safe in icing conditions.
He requested a turn, and this was denied by the controller as there were two other airplanes in the vicinity with similar icing problems.
His best advice about icing is that, if you begin to ice up, to "do something--climb, turn, descend or land." Sometimes "in the terminal area on approach" you might continue if you're sure you'll break out well above ground, but otherwise ice means "do something different" to get out of it.
To increase your icing knowledge, take the advice of pilots "on a mission" to fly in potential icing conditions.
* Know your escape plan before you enter potential icing conditions.
