GEAR UP LNDG.

Narrative

SHORT AND SOFT FIELD TKOFS AND LNDGS WERE BEING CONDUCTED AT POGUE ARPT FOR THE PURPOSE OF REVIEW FOR THE STUDENT'S CERTIFIED FLT INSTRUCTOR CHKRIDE. DURING THE FOURTH PATTERN; AFTER A NORMAL TURN TO DOWNWIND; THE STUDENT WAS PREPARING FOR THE NEXT LNDG. HE WAS ABOUT TO EXTEND THE LNDG GEAR BUT I ADVISED HIM TO WAIT AS THIS LNDG WAS TO BE A SIMULATED EMER LNDG. AT MIDFIELD; I ANNOUNCED ON THE CTAF THAT WE WERE EXECUTING A SHORT APCH TO RWY 17; SIMULATING AN ENG FAILURE. SHORTLY THEREAFTER; ANOTHER ACFT ANNOUNCED A 4 MI FINAL TO THE SAME RWY. ABEAM THE NUMBERS OF RWY 17 I REDUCED PWR TO IDLE AND INSTRUCTED THE STUDENT TO EXECUTE AN EMER LNDG. HE BEGAN A TURN TOWARD THE ARPT. AT THIS TIME THE ACFT ON THE 4 MI FINAL RPTED A 2 MI FINAL TO RWY 17. OUR MODIFIED APCH; IN MY OPINION; WOULD HAVE PLACED US TOO CLOSE TO THE OTHER ACFT FOR A SAFE LNDG. AT THIS TIME; I TOOK CTL OF THE ACFT AND TURNED BACK TO THE DOWNWIND AND INFORMED THE STUDENT TO DISCONTINUE THE EMER APCH IN FAVOR OF ANOTHER SOFT-FIELD APCH. I ALSO TOLD HIM TO TURN TO A BASE LEG WHEN WE WERE ABEAM THE ACFT ON FINAL. THE APCH WAS CONTINUED UNTIL ON ABOUT A 1/4 MI FINAL I NOTICED THE GEAR WAS STILL RETRACTED. AT THE SAME INSTANT; I ALSO NOTICED THAT THE OTHER ACFT THAT LANDED BEFORE US WAS STILL ON THE ACTIVE RWY. THERE WAS SOME DOUBT IN MY MIND AS TO WHETHER WE WOULD LAND BEFORE THE OTHER ACFT HAD EXITED THE RWY. THE STUDENT HAD ALSO DRIFTED OFF OF THE CTRLINE OF THE RWY. WE HAD NOW CROSSED THE THRESHOLD OF THE RWY JUST AS THE OTHER ACFT HAD DEPARTED THE ACTIVE AT THE MIDFIELD TXWY. AT THIS POINT; THE ACFT SETTLED ONTO THE RWY GEAR UP. HOW THE PROB AROSE -- DISTR BY ANOTHER ACFT ON A NON STANDARD APCH AND OUR EFFORTS TO SALVAGE THE LNDG. CONTRIBUTING FACTORS -- ACFT WAS SLOW TO EXIT THE ACTIVE RWY AND I WAS INTENT ON THE STUDENT CORRECTING TO THE CTRLINE. CORRECTIVE ACTIONS -- THE INSTRUCTOR'S (MY GUARD) SHOULD NEVER BE LET DOWN. THROUGH MY PREOCCUPATION OF THE OTHER ACFT AND TRYING TO TEACH I MISSED AN IMPORTANT PRE-LNDG ITEM. IT IS OBVIOUS THAT EACH ITEM ON THE PRE-LNDG CHKLIST SHOULD BE VERIFIED BEFORE THE NEXT ITEM IS COMPLETED. NOTE: THE ACFT'S GEAR AURAL WARNING SYS ONLY SOUNDED AT IDLE PWR; AND THE AUTOMATIC GEAR EXTENSION SYS WAS INOP. I STILL DO NOT KNOW WHY I FAILED TO CATCH THE GEAR BEING UP; IN THE LAST FEW SECONDS BEFORE LNDG I WAS STILL THINKING ABOUT IMPRESSING UPON THE STUDENT THE NEED TO COVER EACH CHKLIST ITEM. I DOUBT VERY SERIOUSLY IF I WILL EVER FORGET ABOUT LNDG GEARS. THE ACFT RECEIVED MINOR DAMAGE AND NO ONE WAS INJURED.
