Narrative:

On a flight from ind to rfd everything was normal until landing. I was on an IFR flight plan and the WX at rfd was VFR. I was cleared for a visibility approach to runway 18. I entered the pattern on a left downwind at 800' AGL. Turn to base and final was normal and I rolled out on the G/south as determined by the VASI lights. Final was normal until T/D. When the nose gear touched down it went down farther than seemed normal, and the aircraft started to porpoise. I heard a loud 'bang' and I applied power to go around. When power was applied the porpoising stopped and since the runway was 8199' long, I determined that I had sufficient runway remaining to allow a safe landing. I stopped easily in the remaining runway. When I turned off the runway I could feel that the nose tire was flat. I shut down the aircraft and got out. On looking at the aircraft I could see that the nose gear was flat and that the propeller had hit the runway and that the nose gear oleo strut had collapsed. At this point I am not aware of any further damage to the aircraft.

Title: PLT OF SMA ON LNDG NOTED THE ACFT ATTEMPTING TO PORPOISE. APPLIED POWER AND PORPOISING STOPPED. REDUCED POWER AGAIN AND CAME TO STOP ON RWY. POSTFLT INSPECTION REVEALED A BLOWN NOSE TIRE, FLAT NOSE STRUT, DAMAGED PROPELLER.

Narrative: ON A FLT FROM IND TO RFD EVERYTHING WAS NORMAL UNTIL LNDG. I WAS ON AN IFR FLT PLAN AND THE WX AT RFD WAS VFR. I WAS CLRED FOR A VIS APCH TO RWY 18. I ENTERED THE PATTERN ON A LEFT DOWNWIND AT 800' AGL. TURN TO BASE AND FINAL WAS NORMAL AND I ROLLED OUT ON THE G/S AS DETERMINED BY THE VASI LIGHTS. FINAL WAS NORMAL UNTIL T/D. WHEN THE NOSE GEAR TOUCHED DOWN IT WENT DOWN FARTHER THAN SEEMED NORMAL, AND THE ACFT STARTED TO PORPOISE. I HEARD A LOUD 'BANG' AND I APPLIED PWR TO GO AROUND. WHEN PWR WAS APPLIED THE PORPOISING STOPPED AND SINCE THE RWY WAS 8199' LONG, I DETERMINED THAT I HAD SUFFICIENT RWY REMAINING TO ALLOW A SAFE LNDG. I STOPPED EASILY IN THE REMAINING RWY. WHEN I TURNED OFF THE RWY I COULD FEEL THAT THE NOSE TIRE WAS FLAT. I SHUT DOWN THE ACFT AND GOT OUT. ON LOOKING AT THE ACFT I COULD SEE THAT THE NOSE GEAR WAS FLAT AND THAT THE PROP HAD HIT THE RWY AND THAT THE NOSE GEAR OLEO STRUT HAD COLLAPSED. AT THIS POINT I AM NOT AWARE OF ANY FURTHER DAMAGE TO THE ACFT.

Pilot of small aircraft on landing noted the aircraft attempting to porpoise. Applied power and porpoising stopped. Reduced power again and came to stop on runway. Postflt inspection revealed a blown nose tire, flat nose strut, damaged propeller.
