Narrative:

Descending at the request of center from FL290 to FL240 into the tops of clouds that my onboard radar and storm scope showed to be 'safe,' I encountered immediate turbulence, windshear, and clear ice. The aircraft flipped over rolling to the right and entered a nose down attitude. The event happened in seconds. The attitude indicator tumbled making it useless and it took me several thousand ft and 40 degrees of heading variation to safely get the aircraft upright and on the proper heading. The gyro recovered several mins later. The whole event was IMC and I recovered at about FL180. The event was so severe that even with the power at idle, the aft exceeded redline. A subsequent inspection revealed no damage. My 1 passenger was not hurt. If the aircraft had been of lesser quality, and I had not had recent simulator training, I doubt that I could have recovered.

Title: TBM-7 PLT HAD ACFT UPSET IN ZFW CLASS A AIRSPACE.

Narrative: DSNDING AT THE REQUEST OF CTR FROM FL290 TO FL240 INTO THE TOPS OF CLOUDS THAT MY ONBOARD RADAR AND STORM SCOPE SHOWED TO BE 'SAFE,' I ENCOUNTERED IMMEDIATE TURB, WINDSHEAR, AND CLR ICE. THE ACFT FLIPPED OVER ROLLING TO THE R AND ENTERED A NOSE DOWN ATTITUDE. THE EVENT HAPPENED IN SECONDS. THE ATTITUDE INDICATOR TUMBLED MAKING IT USELESS AND IT TOOK ME SEVERAL THOUSAND FT AND 40 DEGS OF HDG VARIATION TO SAFELY GET THE ACFT UPRIGHT AND ON THE PROPER HDG. THE GYRO RECOVERED SEVERAL MINS LATER. THE WHOLE EVENT WAS IMC AND I RECOVERED AT ABOUT FL180. THE EVENT WAS SO SEVERE THAT EVEN WITH THE PWR AT IDLE, THE AFT EXCEEDED REDLINE. A SUBSEQUENT INSPECTION REVEALED NO DAMAGE. MY 1 PAX WAS NOT HURT. IF THE ACFT HAD BEEN OF LESSER QUALITY, AND I HAD NOT HAD RECENT SIMULATOR TRAINING, I DOUBT THAT I COULD HAVE RECOVERED.
