## Analysis

WHILE EXECUTING A SINGLE ENGINE ILS APPROACH TO A TOUCH AND GO LANDING, THE CFI PULLED THE MIXTURE CONTROL ON THE RIGHT ENGINE.  UPON LANDING THE PILOT APPLIED FULL POWER TO BOTH ENGINES BUT THE RIGHT ENGINE DID NOT RESPOND. ABOUT 2 FT ABOVE THE RWY THE AIRCRAFT ROLLED TO THE RIGHT AND CONTACTED THE GROUND 100 FT RIGHT OF THE CENTERLINE COLLAPSING THE LEFT MAIN GEAR, NOSE GEAR, AND DAMAGING THE RIGHT WING.
