PLT OF AN SMA SEL DAMAGED THE PROP WHEN HE TOUCHED DOWN ON GEAR UP LNDG AND SUCCESSFULLY WENT AROUND.

Narrative

WHEN FLYING TO W03; THE ALTERNATOR WAS CHANGING FROM CHARGE TO NO CHARGE. I HAD BEEN TRYING TO GET THE ALTERNATOR TO CHARGE BY SWITCHING THE SWITCHES. THIS HAD DISTRACTED ME. ON THE DOWNWIND LEG AT W03 I NEGLECTED TO LOWER THE LNDG GEAR. THERE WAS LOTS OF CHATTER ON THE RADIO; I USE A BOSE AVIATION HEADSET AND FAILED TO HEAR THE GEAR ALARM BUZZER. I WAS LNDG ON RWY 21 AND WITH THE GLARE OF THE SUN I DID NOT NOTICE THAT I DID NOT HAVE A GREEN LIGHT ON THE GEAR. ON FIRST CONTACT WITH THE RWY I REALIZED THAT THE GEAR WAS NOT DOWN AND I IMMEDIATELY ADDED PWR; FLEW THE PATTERN AND LANDED. AFTER LNDG I FOUND THAT THE ENDS OF THE PROP BLADES WERE BENT BACK; ABOUT 2 INCHES. THE END OF THE ROTATING BEACON WAS ROUGH FROM CONTACT WITH THE RWY. THE ANTENNA HAD ROUGH AREAS DUE TO CONTACT WITH THE RWY. I WAS UNABLE TO SEE ANY OTHER DAMAGE. I USED POOR JUDGEMENT BY ALLOWING A MINOR PROB TO DISTRACT ME FROM FLYING THE ACFT. I FEEL VERY FORTUNATE THAT MY RESPONSES WERE FAST ENOUGH TO PREVENT DESTRUCTION OF THE ACFT AS WELL AS MYSELF. WE ALL HAVE OUR PREFLT CHKLIST; OUR RUN-UP CHKLIST; BEFORE TKOF CHKLIST; CLBOUT CHKLIST; CRUISE CHKLIST; LETDOWN AND LNDG CHKLIST. WE SHOULD NEVER FLY UNLESS EACH OF THESE CHKLISTS ARE USED AND EACH ITEM CHKED OFF.
