THE PLT WAS ON A FLT TO OSHKOSH TO AN EAA CONVENTION. WHEN HE ARRIVED, TRAFFIC WAS HVY & SPECIAL TRAFFIC PROCEDURES WERE IN EFFECT. INFO TO ATTENDEES (BEFORE THE CONVENTION) ADVERTISED THAT THE NORTH/SOUTH RWYS WOULD BE USED PRIMARILY FOR DISPLAY ACFT & THE EAST/WEST RWYS WOULD BE IN USE PRIMARILY FOR ITINERANT ACFT; HOWEVER, THERE WAS NO RESTRICTION ON RWY USE. DUE TO HVY TRAFFIC, TWR PSNL DID NOT ROUTINELY OFFER WIND INFO & ALTERNATE RWY USE; HOWEVER, IF REQUESTED, THESE WOULD HAVE BEEN PROVIDED. DRG ARRIVAL, THE PLT EXPECTED TO USE THE NORTH/SOUTH RWY & OBTAINED WIND INFORMATION FROM THE ATIS. HE REALIZED THERE WOULD BE A 12 KT X-WIND, BUT DID NOT BELIEVE THIS WOULD BE A PROBLEM. HE RPRTD THAT DRG ARRIVAL, HE TURNED ONTO A SHORT FINAL APCH FOR RWY 18 & COMPENSATED FOR A STRONG X-WIND BY LOWERING THE RIGHT WING. HE STATED THAT ABOUT 10' ABV THE RWY, THE ACFT ENTERED A RAPID DSCNT & LANDED HARD, BREAKING THE STRUCTURE FOR THE RGT GEAR (WHICH WAS ALSO THE RGT CANARD) & DAMAGED THE PROP.
