Narrative:

Event occurred during landing rollout on runway 17. T/D occurred 'on the numbers' at approximately 60-65 mph indicated, a wheel landing was being accomplished. Approximately 800-900' from T/D the aircraft left the centerline and veered to the right. There was an approximately 10 KT crosswind condition at the time (80-90 degree). There was scattered spots of snow and ice on the runway. At a point about 100-200' prior to the aircraft veering to the right the engine stopped running (I was aware that this was probably going to happen and made no attempt to stop it from happening). At the point where the problem started the tail had been lowered and the aircraft was in a '3 point confign.' there is no doubt that the crosswind velocity and direction was a significant factor in the aircraft leaving the runway. Although it was well within the airplanes capabilities to compensate for this amount of crosswind. The aircraft left the right side of the runway at an estimated speed of 15-20 mph, the landed approximately 100' in compacted snow about 6-10' deep before nosing over and coming to rest upside down. All electrical equipment was immediately turned off and I started exiting the aircraft. Approximately 1 min passed and assistance arrived and helped me get out. There was no fire of fuel spillage. Damage was sustained to the propeller/spinner, canopy/windshield, left wing tip, vertical fin, and a slight wrinkle at the top left fwd fuselage where it meets the engine cowling. There were no injuries. I did make a conscious decision to steer the aircraft between runway lights rather than attempt to keep it on the runway. This was obviously a mistake, since I miscalculated or failed to calculate the effect the snow would have on the aircraft causing it to nose over.

Title: EXPERIMENTAL ACFT VEERS OFF RWY ON LNDG ROLL. ENCOUNTERS SNOW, NOSES OVER.

Narrative: EVENT OCCURRED DURING LNDG ROLLOUT ON RWY 17. T/D OCCURRED 'ON THE NUMBERS' AT APPROX 60-65 MPH INDICATED, A WHEEL LNDG WAS BEING ACCOMPLISHED. APPROX 800-900' FROM T/D THE ACFT L THE CTRLINE AND VEERED TO THE R. THERE WAS AN APPROX 10 KT XWIND CONDITION AT THE TIME (80-90 DEG). THERE WAS SCATTERED SPOTS OF SNOW AND ICE ON THE RWY. AT A POINT ABOUT 100-200' PRIOR TO THE ACFT VEERING TO THE R THE ENG STOPPED RUNNING (I WAS AWARE THAT THIS WAS PROBABLY GOING TO HAPPEN AND MADE NO ATTEMPT TO STOP IT FROM HAPPENING). AT THE POINT WHERE THE PROB STARTED THE TAIL HAD BEEN LOWERED AND THE ACFT WAS IN A '3 POINT CONFIGN.' THERE IS NO DOUBT THAT THE XWIND VELOCITY AND DIRECTION WAS A SIGNIFICANT FACTOR IN THE ACFT LEAVING THE RWY. ALTHOUGH IT WAS WELL WITHIN THE AIRPLANES CAPABILITIES TO COMPENSATE FOR THIS AMOUNT OF XWIND. THE ACFT L THE R SIDE OF THE RWY AT AN ESTIMATED SPD OF 15-20 MPH, THE LANDED APPROX 100' IN COMPACTED SNOW ABOUT 6-10' DEEP BEFORE NOSING OVER AND COMING TO REST UPSIDE DOWN. ALL ELECTRICAL EQUIP WAS IMMEDIATELY TURNED OFF AND I STARTED EXITING THE ACFT. APPROX 1 MIN PASSED AND ASSISTANCE ARRIVED AND HELPED ME GET OUT. THERE WAS NO FIRE OF FUEL SPILLAGE. DAMAGE WAS SUSTAINED TO THE PROP/SPINNER, CANOPY/WINDSHIELD, L WING TIP, VERTICAL FIN, AND A SLIGHT WRINKLE AT THE TOP L FWD FUSELAGE WHERE IT MEETS THE ENG COWLING. THERE WERE NO INJURIES. I DID MAKE A CONSCIOUS DECISION TO STEER THE ACFT BTWN RWY LIGHTS RATHER THAN ATTEMPT TO KEEP IT ON THE RWY. THIS WAS OBVIOUSLY A MISTAKE, SINCE I MISCALCULATED OR FAILED TO CALCULATE THE EFFECT THE SNOW WOULD HAVE ON THE ACFT CAUSING IT TO NOSE OVER.
