Narrative:

Appropriate left pattern flown for runway 27. No other traffic in sight. On final, made runway and over (just past) threshold. Reduced power and began flare. Aircraft bounced/skipped on runway. Porpoised. Heard propeller hit runway. Recovered. Maintained center of runway and slowed. Taxied off of runway onto taxiway and stopped aircraft. Did a checklist shutdown of the aircraft. I could see the tip of the propeller was bent. When I deplaned, saw the nose wheel was flat. I was surprised at the flat nose wheel since my feeling of the force of the bounce was not sufficient to blow the tire on the nose down porpoise. Action taken at the bound up to try to maintain aircraft in ground effect; however, the porpoise nose down occurred quickly. Then action was to complete the landing to a full stop (since the propeller must have been damaged) and clearing the active runway. I am not sure of the actual cause. Possible are: 1) pilot inexperience, hence bounce--although last flying time included 7 successful lndgs to full stop. If this is cause, correctable by flying with an instrument when a long time gap exists between flts; e.g., 60-90 days. 2) nose wheel tire possibly defective, so it blew on the nose down porpoise, hence allowing the propeller to hit the runway. Correction would be a better preflight inspection (although it looked ok during the preflight) or time-log of tire usage. I understood that the FAA inspector classified this as an incident, not an accident.

Title: LOW TIME PLT PORPOISES ACFT ON LNDG, BLOWS TIRE AND STRIKES PROPELLER.

Narrative: APPROPRIATE LEFT PATTERN FLOWN FOR RWY 27. NO OTHER TFC IN SIGHT. ON FINAL, MADE RWY AND OVER (JUST PAST) THRESHOLD. REDUCED PWR AND BEGAN FLARE. ACFT BOUNCED/SKIPPED ON RWY. PORPOISED. HEARD PROP HIT RWY. RECOVERED. MAINTAINED CENTER OF RWY AND SLOWED. TAXIED OFF OF RWY ONTO TXWY AND STOPPED ACFT. DID A CHKLIST SHUTDOWN OF THE ACFT. I COULD SEE THE TIP OF THE PROP WAS BENT. WHEN I DEPLANED, SAW THE NOSE WHEEL WAS FLAT. I WAS SURPRISED AT THE FLAT NOSE WHEEL SINCE MY FEELING OF THE FORCE OF THE BOUNCE WAS NOT SUFFICIENT TO BLOW THE TIRE ON THE NOSE DOWN PORPOISE. ACTION TAKEN AT THE BOUND UP TO TRY TO MAINTAIN ACFT IN GND EFFECT; HOWEVER, THE PORPOISE NOSE DOWN OCCURRED QUICKLY. THEN ACTION WAS TO COMPLETE THE LNDG TO A FULL STOP (SINCE THE PROP MUST HAVE BEEN DAMAGED) AND CLRING THE ACTIVE RWY. I AM NOT SURE OF THE ACTUAL CAUSE. POSSIBLE ARE: 1) PLT INEXPERIENCE, HENCE BOUNCE--ALTHOUGH LAST FLYING TIME INCLUDED 7 SUCCESSFUL LNDGS TO FULL STOP. IF THIS IS CAUSE, CORRECTABLE BY FLYING WITH AN INSTR WHEN A LONG TIME GAP EXISTS BTWN FLTS; E.G., 60-90 DAYS. 2) NOSE WHEEL TIRE POSSIBLY DEFECTIVE, SO IT BLEW ON THE NOSE DOWN PORPOISE, HENCE ALLOWING THE PROP TO HIT THE RWY. CORRECTION WOULD BE A BETTER PREFLT INSPECTION (ALTHOUGH IT LOOKED OK DURING THE PREFLT) OR TIME-LOG OF TIRE USAGE. I UNDERSTOOD THAT THE FAA INSPECTOR CLASSIFIED THIS AS AN INCIDENT, NOT AN ACCIDENT.
