GA SMA GEAR UP LNDG DURING TOUCH AND GO TRAINING FLT.

Narrative

I WAS GIVING DUAL INSTRUCTION IN AN SMA X AT CAPITAL CITY ARPT. WE HAD REQUESTED AND WERE GRANTED CLOSED TFC STATUS TO RWY 30 LEFT HAND PATTERN. THE ACFT OWNER'S WIFE AND MYSELF WERE THE ONLY TWO PERSONS ABOARD AND I WAS ENGAGED IN GIVING TKOF AND LNDG PROCS INCLUDING PWR SETTINGS; FLAP AND GEAR OPS. WE WERE ON DOWNWIND FOR OUR FOURTH AND FIFTH TOUCH AND GO. WE HAD CALLED TWR AND RECEIVED PERMISSION FOR THE TOUCH AND GO AND PROCEEDED WITH PROPER SEQUENCE. WE COMPLETED A PRELNDG CHK AND VIS CHKED A WHEEL DOWN ON EACH SIDE. THIS PROCEDURE WAS REPEATED ON BASE LEG. WE TURNED FINAL APPROX 3/4 TO 1 MI FROM END OF RWY AND ALL WAS WELL. THE TWR WAS USING TWO RWYS FOR TKOFS AT THIS TIME AND AN SMA Y WAS IN POS AND HOLDING ON RWY 26. THIS ACFT WAS CLRED FOR TKOF WHILE WE WERE ON BASE LEG AND UPON TURNING FINAL THE TKOF CLRNC TO THE SMA Y WAS RESCINDED BY THE TWR SEVERAL TIMES; HOWEVER THE SMA Y NEVER ACKNOWLEDGED AND CONTINUED ITS TKOF. AT THIS POINT IN TIME OUR FLT CONDITIONS WERE 20 DEG FLAPS; GEAR DOWN AND PWR REDUCED AND IN MY OPINION WE WERE IN A COMMITTED POS PARTICULARLY SINCE A GO AROUND WAS IMPOSSIBLE DUE TO THE POS OF THE DEPARTING SMA Y. TO THE BEST OF MY RECOLLECTION OUR ALT WAS APPROX 800' MSL 3/4 MI FROM END OF RWY. THE TWR AT THIS POINT GAVE US A LEFT TURN 360 DEG TO REENTER THE FINAL. THIS WAS AN EVASIVE MOVE. AT THIS TIME THE GEAR WAS RETRACTED TO REDUCE DRAG; PWR ADDED TO MAINTAIN ALT. WE WERE LOW AND SLOW PLUS TURNING TOWARD A RIDGE. I FELT THIS WAS AN APPROPRIATE ACTION DUE TO CIRCUMSTANCES AT THE TIME. UPON RETURNING TO SHORT FINAL THE ACFT WAS BEING FLOWN BY THE STUDENT AND NEITHER OF US REMEMBERED TO EXTEND THE GEAR. THE ACFT LANDED GEAR UP WITH MINIMAL DAMAGE AND NO INJURIES. THE FAA IS HANDLING AS AN INCIDENT NOT AN ACCIDENT. WE RECEIVED NO GEAR WARNING HORN DURING THE PWR OFF LNDG. IT IS VERY IMPORTANT TO NOTE THAT THIS ACFT WAS FLOWN ON PREVIOUS OCCASIONS INCLUDING THE DAY BEFORE AND ALL SYS WERE WORKING AND OPERATIONAL. I DID NOTICE DURING THIS FLT; HOWEVER THAT THE HORN DID NOT OPERATE ON ONE OF THE TOUCH AND GO'S WHEN INADVERTENTLY THE FLAPS WERE EXTENDED BEYOND 10 DEG. I CAN'T REMEMBER WHICH PASS IT WAS; BUT I DID MAKE A MENTAL NOTE TO HAVE IT CHKED ON LNDG.
