## Discrepancy

AIRCRAFT WAS ON THE RUNWAY, HOLDING POSITION WITH BRAKES ON IN ORDER TO PERFORM SHORT FIELD TAKE OFF PROCEDURE. THE STUDENT PILOT, UNDER GUIDANCE OF THE CFI, RELEASED THE BRAKES AND THE RIGHT WHEEL GRABBED MOMENTARILY, AS THE LEFT WHEEL STARTED TO MOVE FORWARD. A SECOND LATER, THE RIGHT MAIN GEAR LEG HAD SEPARATED FROM THE AIRCRAFT, CAUSING THE RIGHT WINGTIP AND HORIZONTAL STABILIZER TO CONTACT THE GROUND. IN INSPECTION, THE RIGHT GEAR STRUT HAD SHEARED OFF. THE SHEER WAS VISIBLE THROUGH THE INSPECTION PORT UNDER THE CARPET, BEHIND THE CO-PILOTS SEAT.
