HE CONTINUED TO STATE THAT ON THE LAST LANDING HE TOUCHED DOWN ON THE RUNWAY, THEN ADDED FULL POWER AND RETRACTED THE FLAPS, BUT INADVERTANTLY RETRACTED THE LANDING GEAR. THE AIRCRAFT HIT THE RUNWAY, BOUNCED APRX 25 TO 50 FEET IN THE AIR, SLID OFF THE RUNWAY AND CAUGHT FIRE. THE INSTRUCTOR RATED PILOT AND REGISTERED OWNER IN THE RIGHT SEAT STATED THAT AFTER THE AIRCRAFT INITIALLY BOUNCED, HE COMPLETED THE LANDING.
