SMA LANDS GEAR UP.

Narrative

ON SEVERAL UNSUCCESSFUL ATTEMPTS TO EXECUTE A SIMULATED ENG-OUT PROC; THE OWNER PLT OF THE ACFT IN THE L SEAT WOULD HAVE LANDED FAR SHORT OF THE RWY AND WAS NOT FOLLOWING THE CHKLIST PROPERLY. FINALLY; AFTER A RATHER HARD LNDG IN WHICH WE WERE AT CROSS PURPOSES IN CTLING THE ACFT; I SUGGESTED THAT I DEMONSTRATE THE PROC WHILE HE READ OFF THE CHKLIST ITEMS. THROUGHOUT THE APCH I WAS HAVING TO ASK REPEATEDLY; 'WHAT SHOULD WE BE DOING NEXT?;' EMPHASIZING THE NEED TO RESPOND MORE QUICKLY IN AN EMER SIT LIKE THIS. INSTEAD OF GETTING THROUGH THE CHKLIST; THE OWNER WAS TOO ENGROSSED IN LOOKING AT THE AIRSPD INDICATOR AND WATCHING TO SEE THAT WE WERE GOING TO REACH THE RWY. HE KEPT CALLING OUT THAT WE WERE STILL AT BEST GLIDE. AS WE CROSSED THE THRESHOLD; HE PUT DOWN THE CHKLIST AND SAID 'YOU DID IT.' WE HAD NOT REACHED THE CHKLIST ITEM TO PUT THE LNDG GEAR DOWN AND HEARD METAL SCRAPING BEFORE WE REALIZED IT. ON A PREVIOUS LNDG; WHILE I WAS DEMONSTRATING A SOFT-FIELD LNDG; THE R SEAT HAD SUDDENLY SLIPPED BACK (A PROB WHICH HAD ALSO OCCURRED DURING THE RUNUP AT DULLES). AT THE LAST MOMENT DURING THIS GEAR-UP LNDG; I WAS PREOCCUPIED WITH THE THOUGHT OF BEING READY IN CASE THE SEAT SLIPPED; WHICH PUSHED OUT OF MIND THOUGHTS OF THE LNDG GEAR. THE GREEN GEAR LIGHTS ARE NOT VISIBLE FROM THE R SEAT WITHOUT LEANING INTO THE L SEAT. WHENEVER THE OWNER WAS LNDG; I ROUTINELY LEANED OVER TO CHK THE LIGHTS AND CALL OUT 3 GREEN. ON THIS OCCASION; WHILE INTENT ON MAKING THE RWY AND THE TECHNIQUES OF THE PROC; I WAS 'MAXED OUT' AND FAILED TO DOUBLE CHK.
