Analysis

While on a visual flight plan flight the non-instrument rated plt operated his unpressurized Cessna 210 above the clouds and up to an altitude of 16500 feet MSL. The plt stated that just after passing, 'crazy peak', he encountered extreme turbulence and the acft was sucked down into the clouds below. The plt stated that as the acft entered the clouds he retarded the engine power. Further he said that the acft started a steep descent and banked at least 90 degrees. The acft exited the clouds in an inverted spin at an altitude of about 10000 feet MSL. The acft was substantially damaged during this out-of-control sequence and subsequent spin recovery. The acft was flown to the destination where it landed uneventfully.
