A PA28R PLT LANDS GEAR UP.

Narrative

AFTER PRACTICING A STEEP SPIRAL; SEVERAL CHANDELLS AND LAZY-EIGHTS FOR COMMERCIAL RATING TRAINING; I WENT BACK TO THE ARPT AND PERFORMED SEVERAL (4 OR 5) PRECISION SHORT APCHS IN THE PATTERN. I HAD TO MAKE AN EXTENDED DOWNWIND FOR 2 INCOMING PLANES ON FINAL. AFTER TURNING BEHIND THE LAST PLANE AND BECOMING ESTABLISHED ON FINAL APCH; I BEGAN FOLLOWING THE GS IN; FOR PRACTICE. (RWY 11; ZZZ). MY CONCERN WITH STICKING TO THE GS AND HAVING DONE ALL MY INST TRAINING IN A FIXED GEAR ACFT APPARENTLY DISTR ME FROM DOING A PROPER LNDG CHKLIST; WHICH INCLUDED PUTTING THE GEAR DOWN. PERHAPS A FOOT OFF THE RWY; I REALIZED THE GEAR WAS STILL UP; BUT IT WAS TOO LATE; EVEN THOUGH I APPLIED GAR PWR. THE ACFT THEN CONTACTED THE RWY AND A SMOOTH GLIDE ON THE SURFACE WAS MADE; UNTIL IT STOPPED MOVING. I IMMEDIATELY SHUT OFF THE FUEL IN CASE OF FIRE. SEEING NO FIRE; I CONTACTED THE TWR AND EMER VEHICLES WERE DISPATCHED. I WAS NOT INJURED (EXCEPT FOR FEELING FOOLISH) AND NO FIRE RESULTED. SINCE THE LNDG WAS VERY SMOOTH; NO STRUCTURAL DAMAGE WAS APPARENT TO THE PLANE. THE ENG WILL HAVE TO BE REBUILT BECAUSE OF THE PROP STRIKING THE RWY; OF COURSE.
