Accident occurred JUL-15-84 at CARBONDALE, CO
Aircraft: NORTH AMERICAN P-51D, registration:
N5449V
Injuries: 2 Fatal.

THE PLT WAS PERFORMING AEROBATIC MANEUVERS IN A P-51D THAT HAD BEEN MODIFIED FOR RACING & EXHIBITION. WITNESSES NEAR THE ACCIDENT SITE STATED THAT THE ACFT HAD JUST COMPLETED SEVERAL AEROBATIC MANEUVERS BEFORE IT BEGAN A VERTICAL CLIMB. THE CLIMB WAS TERMINATED AT ABOUT 3000 FT, THEN THE ACFT WENT INTO A NOSE DOWN SPIN. THE ACFT CONTINUED TO SPIN UNTIL GROUND IMPACT. THE PLT HANDBOOK STATES THAT POWER OFF SPINS ARE PERMITTED WHEN STARTED ABOVE 12,000 FT, BUT POWER ON SPINS & SNAP ROLLS ARE PROHIBITED. STALLS ARE COMPARATIVELY MILD & THE ACFT HAS VERY LITTLE TENDENCY TO DROP INTO A SPIN. DURING RECOVERY FROM POWER OFF SPINS, THE ACFT NORMALLY STOPS SPINNING IN 1 TO 1-1/4 TURNS AFTER RECOVERY CONTROLS ARE APPLIED. POWER ON SPINS REQUIRE AS MANY AS 5 TO 6 TURNS & 9000 TO 10,000 FT TO RECOVER.
