Narrative: The weather was excellent except for heavy rain showers approaching the airport from the east. Winds were moderate as reported by control and confirmed on approach by the wind sock on the north side of runway. My approach to the airport was normal and uneventful. Approach directed me to the airport for a straight in landing. No landing traffic was reported and none was seen before or for some time after the incident; heavy rain started within a few minutes after landing. On approach to land; at 130 KTS; I put down the gear and followed soon after with 12 to 13 degrees of flaps; prior to 80 KTS I put on full flaps and maintained that speed until over the end of the runway. Fuel was on both tanks as recommended for landing with approximately 27 gallons remaining; fuel pump on; full rich on the mixture; wheels down; and full increase on the prop in preparation for landing. Everything was normal; aircraft was running perfectly. I performed the GUMPS checklist one more time on final approach. On my approach to landing there was no indication of wind gusts or turbulence. The ride was smooth. The wind was slightly quartering; from the left and required minimal aileron and rudder cross control to maintain centerline alignment. The weather was clear and excellent visual conditions. My previous landing was a similar cross wind but much stronger; reported at 18 gusting to 25. The aircraft handled this without difficulty. Over the runway; with my vision ahead and down the center of the runway and just prior to the main wheels settling on to the surface; I encountered severe wind shear from the left that lifted the left wing. I responded with left aileron down into the wind and cross controlled (right) rudder pedal. I could not maintain directional control of the aircraft and immediately applied full power; still the wind carried me to the right off the runway to the right. As the wind became more across and behind; the aircraft struggled for lift and sunk into the terrain 230 FT from where I thought was going to be making an uneventful touch down on the runway. It all happened very fast and I did not have time to clean up the airplane. The aircraft settled to the ground under full power damaging the aircraft. At a speed near stalling the aircraft was traveling at approximately 60 KTS. 230 FT at 60 KTS takes just a little over 2 seconds. It all happened very quickly and there was no hope for recovery. I am fortunate the aircraft settled as quickly as it did; there is a block wall another 75 yards or so in front of where the aircraft landed. I closed the mixture; shut off the master and exited the aircraft immediately.
