## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

THE STUDENT PILOT RENTED THE AIRCRAFT FROM THE FLIGHT SCHOOL HE WAS ENROLLED WITH FOR SOLO TRAINING. STUDENT PILOT STATED THAT HE PERFORMED THE PREFLIGHT OF THE EXTERIOR AND INTERIOR USING THE POH CHECKLISTS BEFORE THE START OF THE ENGINE AND THAT THE PARKING BRAKE WAS SET. AFTER THE ENGINE WAS STARTED IT IMMEDIATELY WENT TO HIGH RPM AND BEGAN ROLLING FORWARD AND HARD LEFT, STRIKING THE STEEL BEAM OF THE OVERHANG PARKING STRUCTURE WITH THE LEFT WING. THE STUDENT PILOT STATED THAT THE BRAKES SEEMED INEFFECTIVE AS THE AIRCRAFT CONTINUED AROUND THE BEAM PIVOTING ON THE LEFT WING ALL THE WAS AROUND 3/4 OF A FULL TURN UNTIL THE AIRCRAFT STRUCK AND ROLLED OVER A CEMENT DIVIDER APPROXIMATELY 3 INCHES TALL, AT WHICH TIME THE AIRCRAFT ENGINE WAS STOPPED. THERE WAS NO INJURY REPORTED. THE AIRCRAFT ALSO STRUCK THE RIGHT WING ON ANOTHER STEEL BEAM OF THE OVERHANG PARKING STRUCTURE AS IT CAME TO A STOP. MY INVESTIGATION FOUND SUBSTANTIAL DAMAGE TO THE LEFT WING AND RIGHT WING. THE PROPELLER SHOWED SIGNS OF BEING BENT, THOUGH NO EVIDENCE WAS FOUND OF IT STRIKING ANYTHING. DURING THE INVESTIGATION, OPERATIONS ASI ^PRIVACY DATA OMITTED^WAS ASSIGNED AFTER THE STUDENT PILOT LOGS WERE OBTAINED. OPERATIONAL CHECK OF THE THROTTLE, MIXTURE CONTROL, AND BRAKES FOUND NO DISCREPANCIES IN THEIR OPERATIONS.
