After Oshkosh last year a IVP was IMC at 21,000 somewhere over Montana. The ATC controller as well as the Strike Finder reported no cells ahead, but there was a sudden entry into a rather violent cell that produced a several thousand foot per minute ascent. Soon the A/C was at 27,000 ft and there was no opportunity to close the throttle to dump the nose because pressurization would be lost. The pilot reported about 1" of ice on leading edge and golf ball size hail. Close attention to keeping up airspeed successfully averted a stall or other departure from controlled flight. After about three minutes the cell was exited a precautionary landing was made at Missoula. The pressurization heat exchanger had impact damage on the screen and there was minor paint damage on the cowling from hail impact. Otherwise the A/C was not damaged. There was no report that I know of about ice on the tail surfaces. I doubt that there was opportunity to take notice during the encounter. The second actually preceded the above report and occurred about two years ago north of Coeur D'Alene, Idaho. The pilot and a passenger departed Felts Field in Spokane and flew to Coeur D'Alene for fuel. It was night and they departed eastward intending to cross the mountains. They are known to have been circling at fairly low altitude over a lake a few miles from the departure point when the A/C spun into an unoccupied home and ended up in the basement. Both pilot and passenger were killed. The speculation is that they got ice on the airframe and while circling to try to maintain VFR, they decreased speed enough to encounter the fatal spin.
