Narrative:

I was on a cross country, round robin flight beginning at john C tune airport. Before departing jwn, I obtained a standard briefing from nashville FSS by telephone. I also accessed the WX computer at the jwn FBO. I left john tune airport and traveled to tullahoma, tn, where I did 6 touch-and-goes before landing to get gas. I was not on a flight plan. After filling up, I took off from tullahoma and flew northwest to shelbyville, tn. I did a similar number of touch-and-goes at this location before taking off to fly toward maury county's columbia, tn, airport. While traveling west at 2500 ft, I began to observe a dark haze in the distant horizon. Upon closer inspection, I discovered a series of rain cells carrying both heavy rain and lightning. I deviated from my next stop and turned back east and called nashville approach. After speaking of the thunderstorms, bna approach told me that this line of storms extended from my location north into kentucky. It was apparent that it would be impossible for me to return north to john tune airport to land. After identing my position and being given both a squawk code and flight following, nashville approach suggested murfreesboro airport as an alternate. After picking up the AWOS at murfreesboro and reporting the airport in sight, flight following was cancelled and I maneuvered to enter the pattern. I observed the windsock on the ground favoring an approach for runway 18. The winds were gusting badly. As I landed the airplane, a dramatic shift in wind direction occurred. The wind changed direction by 180N degrees and a sudden gust of wind lifted my plane from behind causing it to tip forward. By this time, I had slowed my airplane to a taxi speed and had entered the taxiway when my plane toppled over onto its nose.

Narrative: I WAS ON A XCOUNTRY, ROUND ROBIN FLT BEGINNING AT JOHN C TUNE ARPT. BEFORE DEPARTING JWN, I OBTAINED A STANDARD BRIEFING FROM NASHVILLE FSS BY TELEPHONE. I ALSO ACCESSED THE WX COMPUTER AT THE JWN FBO. I LEFT JOHN TUNE ARPT AND TRAVELED TO TULLAHOMA, TN, WHERE I DID 6 TOUCH-AND-GOES BEFORE LNDG TO GET GAS. I WAS NOT ON A FLT PLAN. AFTER FILLING UP, I TOOK OFF FROM TULLAHOMA AND FLEW NW TO SHELBYVILLE, TN. I DID A SIMILAR NUMBER OF TOUCH-AND-GOES AT THIS LOCATION BEFORE TAKING OFF TO FLY TOWARD MAURY COUNTY'S COLUMBIA, TN, ARPT. WHILE TRAVELING W AT 2500 FT, I BEGAN TO OBSERVE A DARK HAZE IN THE DISTANT HORIZON. UPON CLOSER INSPECTION, I DISCOVERED A SERIES OF RAIN CELLS CARRYING BOTH HVY RAIN AND LIGHTNING. I DEVIATED FROM MY NEXT STOP AND TURNED BACK E AND CALLED NASHVILLE APCH. AFTER SPEAKING OF THE TSTMS, BNA APCH TOLD ME THAT THIS LINE OF STORMS EXTENDED FROM MY LOCATION N INTO KENTUCKY. IT WAS APPARENT THAT IT WOULD BE IMPOSSIBLE FOR ME TO RETURN N TO JOHN TUNE ARPT TO LAND. AFTER IDENTING MY POS AND BEING GIVEN BOTH A SQUAWK CODE AND FLT FOLLOWING, NASHVILLE APCH SUGGESTED MURFREESBORO ARPT AS AN ALTERNATE. AFTER PICKING UP THE AWOS AT MURFREESBORO AND RPTING THE ARPT IN SIGHT, FLT FOLLOWING WAS CANCELLED AND I MANEUVERED TO ENTER THE PATTERN. I OBSERVED THE WINDSOCK ON THE GND FAVORING AN APCH FOR RWY 18. THE WINDS WERE GUSTING BADLY. AS I LANDED THE AIRPLANE, A DRAMATIC SHIFT IN WIND DIRECTION OCCURRED. THE WIND CHANGED DIRECTION BY 180N DEGS AND A SUDDEN GUST OF WIND LIFTED MY PLANE FROM BEHIND CAUSING IT TO TIP FORWARD.
