## Analysis

THE PLT STATED THAT HE WAS GIVING LOCAL SIGHTSEEING FLIGHTS.HE INDICATED THAT A 'WIDE' GENTLEMAN AND A 'MODERATE' SIZE GENTLEMAN BOARDED THE ACFT. THE PLT MOVED THE THROTTLE TO ENSURE CLEARANCE BUT FOUND ONE OF THE PAX RESTRICTED THE MOVEMENT SLIGHTLY. THE PAX WAS REPOSITION AND THE PLT INITIATED THE FLIGHT. THE ACFT WOULD NOT ATTAIN FULL POWER AND THE PLT COULD NOT MOVE THE THROTTLE THRU ITS FULL RANGE OF TRAVEL. THE GRASS STRIP USED FOR TAKEOFF WAS ROUGH AND THE ACFT LIFTED OF PREMATURELY. THE PLT ABORTED THE TAKEOFF AND DURING THE GROUND ROLL HE USED THE BRAKES TO CONTROL THE ACFT ATTITUDE. THE ACFT ROLLED OVER A SLIGHT BUMP AND THE TAIL LIFTED CAUSING THE PLT TO SHIFT FORWARD ONTO THE BRAKES, WHICH AGGREVATED THE TAIL-HIGH ATTITUDE. THE ACFT NOSED OVER.
