A cirrus crashed in Lancaster, CA, in the last day or so; parachute deployed in the pattern, with all dead, I believe. That was something like the 14th fatal crash out of 31 in the last few years.
I've decended out of cloud under canopy in the winter with ice on the canopy, and a coating of ice on my chest, arms, lets, and face.
Below is a clip I saw and pasted from another site about the latest Cirrus accident-- great points consistent w/ Avbugs recent essays on a recent thread about non-certified aircraft launching into icing.
Good info also on icing and reference to a current article apparently from the author of the comments that follow -- all worth studying -esp if you are on the ground in warm air w/ a clean airframe and a frosty mug in your hand.

Yet another Cirrus accident! This afternoon while departing Birmingham, AL. "Experienced" pilot of an SR22 (no TKS) flew through an icing layer 3000-4000 ft thick after the passage of a cold front. Was on top at 8000 feet and the aircraft departed controlled flight. CAPS was activated, all three souls on board survived.
I cannot understand why pilots, experienced or not, attempt to challenge Mother Nature with little or no regard for the potential outcome.
The chances of icing was near certain. I'll say that another way. THERE WAS NO DOUBT THAT ICING WOULD OCCUR.
1. An AIRMET for icing existed which included Birmingham.
2. Strong cold front passed by earlier in the afternoon.
3. Strong cold-air advection behind the front lowering freezing levels throughout the day.
4. Saturated conditions (0°C dew point depression) from 3,500 ft through 6,700 ft with temperatures of 0°C at 3,500 ft to -5°C at the cloud tops around 7,000 ft. Very high risk of supercooled water droplets in the presence of cold-air advection = A high risk of severe icing.
If anyone doesn't get IFR Magazine, please read my latest article,
The Appleman Line, which illustrates the atmospheric conditions that can produce icing.
