THE PLT RENTED THE ACFT & REPORTED THAT HE & HIS FRIEND WOULD BE GOING ON A LOCAL FLT. A WITNESS STATED THAT HE SAW THE ACFT FLY OVER AT AN ESTIMATED 1000 TO 1500 FT AGL. REPORTEDLY, THE ACFT WAS IN LEVEL FLT WHEN THE PLT 'CUT' THE POWER, THE ACFT 'NOSED UP A LITTLE BIT', THEN ENTERED A SPIN. ANOTHER WITNESS STATED THAT SHE SAW THE ACFT & THOUGHT THAT 'THEY WERE DOING SOME KIND OF STUNT.' SUBSEQUENTLY, THE ACFT IMPACTED THE GROUND IN A NOSE DOWN ATTITUDE. THE WRECKAGE WAS CONFINED WITHIN THE DIMENSIONS OF THE ACFT. NO PREIMPACT/MECHANICAL FAILURE OR MALFUNCTION WAS FOUND.
