Flight Crew Human Performance
I was about a mile from the FAF for runway 27; was asked if I wanted the visual or continue on the ILS. I advised the controller I had the field in sight but wanted to continue on the ILS to be safe. The controller turned me in 30 degrees or so and cleared me for the approach. I joined the ILS; the glideslope fell in and the approach was quite pretty if I do say so myself. I crabbed into the wind a bit to maintain the localizer. The winds were coming from my 10-11 O'clock. The ride got quite bumpy all of a sudden on approach. I was little fast on the approach so I chopped the throttle back a bit. By the time I crossed threshold I had 20 degrees of flaps out and greased a sweet landing. The roll out went fine. I got the plane cleaned up and slowed down to almost a complete stop; let off the brakes and started a left turn on taxiway 2A. When I was about 45 degrees into the turn; all of a sudden the right wing jumped up and tipped the plane to the left. It happened so fast that I had no time to react. People always say that things happen in slow motion when the crap hits the fan. Well that right wing was popped up so fast but it seemed like we hung up there forever. I pulled the throttle the rest of the way back and pulled the elevator back for full deflection. This dropped the tail back down ever so gently (or so it seemed). While we were hanging in the air I heard that god awful sound of metal grinding; but only for a very short time. Once the plane settled down I gently gave it throttle and taxied past the hold short line and switched to ground. At this point I didn't know what I heard grinding but figured since the engine was still running it couldn't have been the propeller. I taxied up to the ramp at company and shut it down. Everything sounded and acted normal with the plane and engine. When the propeller finally stopped and I started unbuckling I noticed it. About the first two inches of the propeller were rolled back almost 90 degrees. The metal grinding sound I heard was the propeller hitting the concrete of the runway.

Title: C172 PLT LOSES CTL DURING TAXIING CLR OF THE RWY AND HAS A PROP STRIKE AT MEM.
Narrative: I WAS ABOUT A MILE FROM THE FAF FOR RWY 27; WAS ASKED IF I WANTED THE VISUAL OR CONTINUE ON THE ILS. I ADVISED THE CTLR I HAD THE FIELD IN SIGHT BUT WANTED TO CONTINUE ON THE ILS TO BE SAFE. THE CTLR TURNED ME IN 30 DEGS OR SO AND CLRED ME FOR THE APCH. I JOINED THE ILS; THE GLIDESLOPE FELL IN AND THE APCH WAS QUITE PRETTY IF I DO SAY SO MYSELF. I CRABBED INTO THE WIND A BIT TO MAINTAIN THE LOC. THE WINDS WERE COMING FROM MY 10-11 O'CLOCK. THE RIDE GOT QUITE BUMPY ALL OF A SUDDEN ON APCH. I WAS LITTLE FAST ON THE APCH SO I CHOPPED THE THROTTLE BACK A BIT. BY THE TIME I CROSSED THRESHOLD I HAD 20 DEGS OF FLAPS OUT AND GREASED A SWEET LNDG. THE ROLL OUT WENT FINE. I GOT THE PLANE CLEANED UP AND SLOWED DOWN TO ALMOST A COMPLETE STOP; LET OFF THE BRAKES AND STARTED A LEFT TURN ON TXWY 2A. WHEN I WAS ABOUT 45 DEGS INTO THE TURN; ALL OF A SUDDEN THE R WING JUMPED UP AND TIPPED THE PLANE TO THE LEFT. IT HAPPENED SO FAST THAT I HAD NO TIME TO REACT. PEOPLE ALWAYS SAY THAT THINGS HAPPEN IN SLOW MOTION WHEN THE CRAP HITS THE FAN. WELL THAT R WING WAS POPPED UP SO FAST BUT IT SEEMED LIKE WE HUNG UP THERE FOREVER. I PULLED THE THROTTLE THE REST OF THE WAY BACK AND PULLED THE ELEVATOR BACK FOR FULL DEFLECTION. THIS DROPPED THE TAIL BACK DOWN EVER SO GENTLY (OR SO IT SEEMED). WHILE WE WERE HANGING IN THE AIR I HEARD THAT GOD AWFUL SOUND OF METAL GRINDING; BUT ONLY FOR A VERY SHORT TIME. ONCE THE PLANE SETTLED DOWN I GENTLY GAVE IT THROTTLE AND TAXIED PAST THE HOLD SHORT LINE AND SWITCHED TO GND. AT THIS POINT I DIDN'T KNOW WHAT I HEARD GRINDING BUT FIGURED SINCE THE ENGINE WAS STILL RUNNING IT COULDN'T HAVE BEEN THE PROP. I TAXIED UP TO THE RAMP AT COMPANY AND SHUT IT DOWN. EVERYTHING SOUNDED AND ACTED NORMAL WITH THE PLANE AND ENGINE. WHEN THE PROP FINALLY STOPPED AND I STARTED UNBUCKLING I NOTICED IT. ABOUT THE FIRST TWO INCHES OF THE PROP WERE ROLLED BACK ALMOST 90 DEGS. THE METAL GRINDING SOUND I HEARD WAS THE PROP HITTING THE CONCRETE OF THE RWY.
