Narrative:
As I remember the winds were reported as calm or marginal. About 1/2 mi from touchdown, I noticed a crosswind component from the right. After the analysis of this I corrected for the crosswind and was back on for the approach. Right before touchdown I brought the plane out of the correction and had a soft landing (no bounce) on the back, 2 tires. Before the nose could touchdown, a crosswind hit the front right quadrant of the plane, pushing the nose. The plane attempted to drop its front left quadrant. At this time I tried to raise the nose, and gained altitude. The aircraft had however slowed down too much to gain much altitude and I was afraid of what the plane would do at that slow of an airspeed so low to the ground. At this time I tried to settle the plane back down and pulled the throttle back. I slowly braked as necessary as not to FLIP or ground loop. When the plane came to a stop the propeller was still spinning because I didn't have the time to pull the mixture all the way out. I performed my aircraft shutdown procedures, and afterwards turned the master and avionics switches back on, so as to communicate with tower further. I left both switches on until the firemen arrived and then turned them off so as to not set off any live magneto. Before turning off the radio I heard tower still reporting calm wind when the windsock to my left was now blowing to the west steadily. The incident occurred simply because a freak wind gust.

Title: SPI ENCOUNTERS WIND GUSTS ON LNDG HAS LOSS OF ACFT CTL.
Narrative: AS I REMEMBER THE WINDS WERE RPTED AS CALM OR MARGINAL. ABOUT 1/2 MI FROM TOUCHDOWN, I NOTICED A XWIND COMPONENT FROM THE R. AFTER THE ANALYSIS OF THIS I CORRECTED FOR THE XWIND AND WAS BACK ON FOR THE APCH. RIGHT BEFORE TOUCHDOWN I BROUGHT THE PLANE OUT OF THE CORRECTION AND HAD A SOFT LNDG (NO BOUNCE) ON THE BACK, 2 TIRES. BEFORE THE NOSE COULD TOUCHDOWN, A XWIND HIT THE FRONT R QUADRANT OF THE PLANE, PUSHING THE NOSE. THE PLANE ATTEMPTED TO DROP ITS FRONT L QUADRANT. AT THIS TIME I TRIED TO RAISE THE NOSE, AND GAINED ALT. THE ACFT HAD HOWEVER SLOWED DOWN TOO MUCH TO GAIN MUCH ALT AND I WAS AFRAID OF WHAT THE PLANE WOULD DO AT THAT SLOW OF AN AIRSPD SO LOW TO THE GND. AT THIS TIME I TRIED TO SETTLE THE PLANE BACK DOWN AND PULLED THE THROTTLE BACK. I SLOWLY BRAKED AS NECESSARY AS NOT TO FLIP OR GND LOOP. WHEN THE PLANE CAME TO A STOP THE PROP WAS STILL SPINNING BECAUSE I DIDN'T HAVE THE TIME TO PULL THE MIXTURE ALL THE WAY OUT. I PERFORMED MY ACFT SHUTDOWN PROCS, AND AFTERWARDS TURNED THE MASTER AND AVIONICS SWITCHES BACK ON, SO AS TO COMMUNICATE WITH TWR FURTHER. I LEFT BOTH SWITCHES ON UNTIL THE FIREMEN ARRIVED AND THEN TURNED THEM OFF SO AS TO NOT SET OFF ANY LIVE MAGNETO. BEFORE TURNING OFF THE RADIO I HEARD TWR STILL RPTING CALM WIND WHEN THE WINDSOCK TO MY L WAS NOW BLOWING TO THE W STEADILY. THE INCIDENT OCCURRED SIMPLY BECAUSE A FREAK WIND GUST.
