LAKE 270 NOSE GEAR STUCK UP DURING LNDG CAUSING DAMAGE TO THE GEAR DOORS AND HULL KEEL.

Narrative

I DEPARTED TULLY LAKE; NY; WITH MY LAKE RENEGADE AND 2 PAX. R SEAT WAS A CFI WITH MANY OTHER RATINGS. MY PAX WAS TRYING TO BE HELPFUL WITH GUMP CHK; ETC. HOWEVER; IT DISRUPTED MY NORMAL FLOW PATTERN AND VISUAL CHKS. HE REGULARLY LANDS AT THIS ARPT AND SAID 'YOU ARE LINED UP FOR A STRAIGHT-IN ON RWY 33.' I SAID 'OK.' AS I DID MY FLOW CHK AND LOWERED THE GEAR AND FLAPS; HE SAID 'GOT R GEAR; GOT L GEAR.' WE WERE GETTING SOME LIGHT TURB AND I WAS CONCENTRATING ON FLYING THE AIRPLANE. I HAD FAILED TO VISUALLY CHK THE NOSE GEAR. THE MAINS CONTACTED THE RWY; THE NOSE CAME DOWN CONSIDERABLY LOWER THAN NORMAL; AND A SCRAPING SOUND WAS HEARD. OTHERWISE; THE ACFT WAS UNDER COMPLETE CTL. I STOPPED THE ACFT. THE 3 OF US GOT OUT. I HAD MY FRIEND PUSH THE TAIL DOWN WHICH HELD THE NOSE UP. I USED MY BOAT PADDLE TO ALIGN THE TIRE THAT HAD CONTACTED THE GEAR DOORS THAT PREVENTED THEM FROM OPENING. THE GEAR CAME DOWN AND I TAXIED THE AIRPLANE TO THE RAMP. I DID A CLOSE INSPECTION AND NOTED APPROX 1 1/2 FT OF THE KEEL HAD EXTENSIVE WEAR. WE WENT IN FOR BREAKFAST. WHILE EATING; I CALLED AN A&P MECH TO CHK THE PLANE PRIOR TO FLT; BUT WAS UNABLE TO GET ANYONE THAT COULD COME THAT DAY. PRIOR TO FINISHING BREAKFAST; OUR WAITRESS INFORMED ME THAT THE FAA WAS ON THE PHONE. THEY REQUESTED THAT I LEAVE THE PLANE FOR THEM TO INSPECT -- I AGREED. ON TUESDAY MORNING; 2 FAA INSPECTORS; MYSELF; AND A MECH ALL LOOKED THE AIRPLANE OVER. WE JACKED THE NOSE AND CYCLED THE GEAR. NOTING THERE WAS NO APPARENT PROB. I WAS ISSUED A FERRY PERMIT TO TAKE THE AIRPLANE TO ANOTHER FACILITY FAMILIAR WITH THIS PARTICULAR ACFT AND HAVE IT REPAIRED.
