GEAR UP LNDG IN SINGLE SMA.

Narrative

I LANDED MY SMA WITH THE LNDG GEAR RETRACTED. I ENTERED THE TFC PATTERN A LITTLE TOO FAST TO LOWER THE GEAR AT MY USUAL POS ON THE DOWNWIND LEG. I BECAME DISTRACTED WATCHING FOR A STUDENT PLT WHO WAS FLYING AHEAD OF ME. WHEN I LOOKED DOWN TO CHK MY SPD; I MOMENTARILY LOST HIM AND ONCE I FOUND HIM; I HAVE TOO MUCH OF MY ATTN TO WATCHING OUT FOR HIM. I THOUGHT I HAD SLOWED DOWN AND DROPPED THE GEAR. BEING THIS DISTRACTED; I NEGLECTED TO GO THROUGH MY USUAL PROC AND DIDN'T USE MY NORMAL GUMP PROC. I LOWERED MY FLAPS AND PROCEEDED DOWN THE FINAL APCH. I DIDN'T HEAR THE WARNING HORN; AND OBVIOUSLY DIDN'T LOOK AT THE LIGHTS OR INDICATOR. I WAS UNAWARE OF MY MISTAKE UNTIL THE PROP HIT THE GND (RWY). RECURRENT TRAINING SHOULD EMPHASIZE THE USE OF THE CHKLIST AND A FINAL CHK OF ALL SYS AS THE TURN IS MADE ONTO FINAL. ONE SHOULD NEVER ALLOW HIS ATTN TO BE DIVERTED SO AS TO NEGLECT THE FINAL CHK. I WILL PLACE A PLACARD IN A VERY OBVIOUS PLACE AND WILL SUGGEST TO ALL MY PLT FRIENDS THAT THEY DO LIKEWISE. ONE IS NEVER TOO EXPERIENCED TO USE A CHKLIST.
