PLT OF SMA GA ACFT ACCIDENTLY WAS LNDG WITH 'GEAR UP' AND RECOGNIZED THE ERROR IN TIME TO ONLY STRIKE THE PROP BEFORE EXTENDING THE 'GEAR.'

Narrative

I WAS FLYING AN SMA SEL TO GREATER KANKAKEE ARPT (IKK) ON A CLR; LATE WINTER DAY. THE CONDITIONS WERE PLEASANT. I WAS RELAXED; AS IT TURNED OUT; TOO RELAXED. ALONG WITH ME FOR THE RIDE WAS ANOTHER PLT/FRIEND. ENRTE I PERFORMED STEEP TURNS; SOMETHING I TRY TO DO WHENEVER I GET THE CHANCE TO MAINTAIN SKILLS. I ALSO PERFORMED A TOUCH-AND- GO LNDG AT KANKAKEE; AND INTENDED TO PERFORM ANOTHER. THE OTHER PLT HAD NOT BEEN UP IN A SMALL PLANE FOR AWHILE. HE HAD BEEN WORKING AS A CHARTER PLT; FLYING BUSINESS JETS. AS I APCHED FOR THE SECOND LNDG; PERHAPS 1/4 MI OUT; I THOUGHT MY FRIEND MIGHT WANT TO MAKE A LNDG. I TOLD HIM 'IT'S YOURS.' HE ACCEPTED; BUT ASKED ME TO CONTINUE FLYING THE ACFT WHILE HE ADJUSTED HIS SEAT. HE TOOK OVER THE CTLS AND AS HE FLARED FOR THE LNDG; WE HEARD A SCRAPING SOUND. WE BOTH IMMEDIATELY REALIZED THE GEAR WAS STILL UP. HE ADDED ENOUGH PWR TO CLB A FEW FT ABOVE THE LONG RWY. I LOWERED THE GEAR SWITCH AND WAITED FOR THE '3 GREEN' GEAR DOWN INDICATION. THEN MY FRIEND LANDED THE PLANE. I TAXIED TO THE RAMP AND SHUT DOWN. DURING THE FIRST TOUCH-AND-GO APCH; I MENTALLY PERFORMED THE GUMP CHK. ON THE SECOND APCH; I OBVIOUSLY DIDN'T; BUT I THOUGHT I DID. WHEN MY FRIEND ASKED GUMP CHK; I ANSWERED 'YES.' I NEGLECTED TO ENUMERATE EACH ITEM. I HAVE NO EXPERIENCE WITH DUAL-PLT OP. MY FRIEND DOES. AS I MADE TURNS; HE CALLED TFC CHKS; I CALLED FLAP POS AND SPD. IN RETROSPECT; THAT INFORMAL DUAL-PLT PROC APCH MADE ME RELAX TOO MUCH. IT MADE ME ASSUME HE WAS PICKING UP SOME DUTIES. HE ASSUMED I WAS DOING THINGS AND I MISINFORMED HIM ABOUT THE GEAR. I WAS NOT CONCENTRATING ON PROC LIKE I SHOULD HAVE BEEN; BECAUSE I WAS SPENDING SOME TIME INTERACTING IN THE COCKPIT. ONE OTHER FACTOR. THE AUTO GEAR EXTENSION SYS; WHICH IS SUPPOSED TO SOUND A HORN AND LOWER THE GEAR WITH LOW AIRSPD AND THROTTLE RETARDATION; DID NOT WORK. IN SHORT; MY TOO-INFREQUENT FLTS INVOLVING DIFFERENT RENTAL ACFT; COUPLED WITH A TOO-RELAXED APCH; ALMOST LED TO DISASTER. I MUST REMEMBER A BASIC: FOLLOW PROC!
