GA SMA GEAR UP LNDG.

Narrative

AFTER CHKING THE ACFT OUT AND FINDING ALL SYSTEMS WORKING PROPERLY; I FLEW THE ACFT FROM HILLSBORO ARPT TO AURORA ARPT FOR TOUCH AND GOES. AURORA WAS FIELD OF CHOICE FOR PRACTICE BECAUSE OF THE LOW TFC DENSITY. THE WX WAS SLIGHTLY HAZY AND CLEARING QUICKLY. I CALLED AURORA UNICOM 122.7 FOR A FIELD ADVISORY AND WAS GIVEN RWY 17 AS THE PREFERRED RWY; LEFT TFC. THERE WAS NO APPARENT WIND. I PROCEEDED TO MAKE 4 TOUCH AND GOES. EACH TOUCH AND GO WAS MADE FROM A DIFFERENT SITUATION; PATTERN ALT CLOSE IN; PATTERN ALT NORMAL; PATTERN ALT TURNING BASE EARLY; LATE; ETC. THE LNDGS WERE GOING EXTREMELY WELL. THE LAST 2 WERE SO SMOOTH THAT I WONDERED IF I HAD REALLY TOUCHED DOWN. MY THOUGHT TRAIN WAS; 'I'LL MAKE THIS ONE PERFECT AND WILL TAKE HER HOME.' I WAS FOLLOWING A TWIN WHO WAS SHOOTING LNDGS AS WELL. THE TWIN HAD EXTENDED SO I EXTENDED MY DOWNWIND. I LOWERED THE FLAPS AND TRIMMED BUT DID NOT LOWER THE GEAR. I WAS CONCENTRATING ON THE CLRNC DISTANCE BTWN THE TWIN AND MYSELF; AND WHEN THE DISTANCE WAS CORRECT I BEGAN CONCENTRATING ON THAT PERFECT T/D. WHEN THE PWR WAS PULLED AT THE NUMBERS; THE HORN THAT SOUNDED WAS THE STALL WARNING IN MY MIND'S EYE. THE FIRST INDICATION THAT THE ERROR HAD OCCURRED WAS WHEN THE PROP BEGAN CURLING BACK. THERE WAS NOTHING TO DO BUT KEEP THE ACFT AS TRIM AS POSSIBLE; GET THE GAS AND ELECTRICAL OFF AND GET OUT IMMEDIATELY AFTER THE ACFT STOPPED. THE ACFT T/D'ED LIGHTLY; CAUSING MINIMUM DAMAGE. THE ERROR OF POOR ATTN AND CONCENTRATION ON REVIEW OF LNDG CHKS CAUSED THIS ACCIDENT.
