SMA STUDENT PLT AND INSTRUCTOR LAND GEAR UP DUE TO DISTRS FROM PATTERN TFC AND TRAINING.

Narrative

MY INSTRUCTOR AND I WERE PRACTICING ENG OUT PROCS AND LNDGS ON RWY 18. WHEN THE ACFT WAS ABEAM THE NUMBERS ON RWY 18 FOR A L DOWNWIND; MY INSTRUCTOR PULLED THE PWR TO THE ACFT TO SIMULATE ENG OUT PROCS. WE WERE AT PATTERN ALT; SOME STEEP SPIRAL WAS REQUIRED. BEFORE I COULD MAKE ANY CHANGES TO THE CONFIGN OF THE ACFT; I NOTICED A PLANE TURNING FROM BASE TO FINAL FOR RWY 18. AT OUR PARTICULAR POS AT THAT TIME; WE WOULD HAVE CUT THE OTHER ACFT OFF. WE CHOSE TO INCREASE PWR AND EXTEND THE DOWNWIND LEG. WHEN WE TURNED FINAL; MY INSTRUCTOR PULLED THE PWR. ALL OF MY ATTN WAS FOCUSED ON MY AIRSPD AND MAKING THE RWY. I DID MY GUMPS CHK; BUT DID NOT CHK FOR THE GEAR DOWN. WE TOUCHED DOWN JUST PAST THE NUMBERS AND HEARD A LOUD SCREECHING SOUND. AT THAT POINT WE REALIZED WHAT HAD HAPPENED. AFTER THE INITIAL IMPACT WHICH WAS WITH FULL FLAPS; PWR ALL THE WAY OUT; AND A TOUCHDOWN SPD OF ABOUT 50 KTS; MY INSTRUCTOR IMMEDIATELY PULLED THE MIXTURE BACK TO KILL THE ENG. ONCE WE CAME TO A COMPLETE STOP ABOUT 450 FT PAST THE NUMBERS; WE MADE RADIO CALLS FOR OTHER ACFT IN THE PATTERN TO GO AROUND. WE THEN SHUT OFF THE MASTER AND IGNITION SWITCHES. WE GOT DISTR AND OUT OF RHYTHM WATCHING THE OTHER TFC AND ASSUMED THAT WE HAD ALREADY DONE WHAT WAS NEEDED. SUPPLEMENTAL INFO FROM ACN 618119: UPON EVALUATING THE ACCIDENT; I SHOULD HAVE MADE THE DECISION TO ABORT THE 180 DEG ACCURACY ENG OUT AND MAKE IT A GAR. WE BOTH LEARNED WHAT HAPPENS IF YOU ARE DISTR FROM YOUR BASIC HABIT PATTERN. MY STUDENT AND I WERE DISTR BY THE OTHER TFC AND THE DECISIONS WE MADE FORMED A NEGATIVE CHAIN OF EVENTS.
