DURING TAILWHEEL TYPE ACFT TRAINING; IN A CHAMPION CITABRIA CH9; THE PVT PLT TRAINEE STRUCK THE PROP DURING A WHEEL LNDG RESULTING IN THE PLT INSTRUCTOR ABORTING THE TOUCH-AND-GO TKOF IN ORDER TO CHK FOR PROP DAMAGE. THE PROP WAS FOUND TO BE BENT AT THE TIPS.

Narrative

I AM CURRENTLY TAKING TAILWHEEL LESSONS. TODAY'S LESSON WAS TOUCH-AND-GOES AT PAINE FIELD (22 NM N OF BOEING FIELD; ACFT'S HOME BASE). WINDS WERE FAIRLY STRONG; WITH A SMALL XWIND COMPONENT. FIRST 2 LNDGS WERE UNEVENTFUL; BUT BOTH HAD SLIGHT BOUNCES. LNDGS WERE PWR ON. SECOND LNDG REQUIRED A SHOT OF PWR TO SMOOTH THE BOUNCE. AFTER SECOND LNDG; A B747 DEPARTED. THIRD LNDG WAS PWR OFF DEMONSTRATION BY INSTRUCTOR; WITH SMALL BOUNCE. FOURTH LNDG WAS PROP STRIKE. FOURTH LNDG WAS PWR IDLE ABEAM THE NUMBERS ON DOWNWIND. BASE WAS CLOSE TO RWY DUE TO STRONG HEAD WINDS. FINAL WAS ALIGNED WITH RWY R OF CTRLINE. APCH WAS APPROX 80 MPH (CITATION MODEL 7G(AA)). TOUCHDOWN SEEMED GENTLE AND STICK WAS MOVED FORWARD AGGRESSIVELY TO PREVENT BOUNCE. HEARD 'STRANGE SOUND' AND THOUGHT IT MIGHT BE PROP STRIKE. ACFT BOUNCED APPROX 5 FT AND TOUCHED DOWN. I ASKED INSTRUCTOR IF THAT WAS PROP STRIKE. ENG SOUNDED NORMAL AND PWR WAS ADDED FOR TKOF; WHILE TAIL WAS UP. INSTRUCTOR CALLED TO REJECT TKOF. HE PULLED OFF TO TXWY TO CHK PROP. 1 BLADE TIP BENT FORWARD; 1 BENT BACKWARDS. I HAVEN'T HAD TROUBLE MAINTAINING STRAIGHT ROLLOUT/TKOF. I THINK I MAY HAVE BEEN TOO AGGRESSIVE PUSHING FORWARD BECAUSE FIRST 2 LNDGS WERE MILD BOUNCES. I WANTED TO AVOID THE BOUNCE; WAS INSTRUCTED 'NOT TO WORRY ABOUT PROP STRIKE' AND TO 'PLANT' ACFT ON GND. THE AIRPLANE FELT LIKE IT WAS UNDER CTL AND THERE WAS NO INDICATION THAT THE LNDG WAS TOO NOSE FORWARD OR TOO HARD.
