## Analysis

THE ACFT CRASHED WHILE SPINNING AFTER ONLY A FEW MINUTES FLT. THE ACFT HAD JUST BEEN FLOWN BY ANOTHER PLT FOR APRX 20 MINUTES JUST PRIOR TO THE ACCIDENT FLT. THIS PLT/OWNER SAID THE ACFT OPERATED IN A TROUBLE FREE MANNER. DURING THE ACCIDENT FLT THE PLT MADE A HIGH SPEED PASS OVER THE RWY AFTER TAKEOFF AND PULLED UP IN A STEEP CLIMB. THE ACFT THEN ENTERED A SPIN TO THE RIGHT WHICH ENDED IN THE CRASH WITH AN INTENSE GROUND FIRE THAT DESTROYED THE ACFT. THERE WERE NO MECHANICAL MALFUNCTIONS REVEALED AND THE PHYSICAL EXAMINATION OF THE PLT SHOWED NO PRE-ACCIDENT IMPAIRMENTS WHICH WOULD HAVE INTERFERED WITH THE PROPER OPERATION OF THE ACFT.
