## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- In flight collision with terrain/water, maneuvering
  - autorotation - improper, pilot in command (cause)
  - altitude - misjudged, pilot in command (cause)

## Analysis

DURING AN AIRSHOW, THE PLT TOOK OFF TO PERFORM A PLANNED 8-SPIN AUTOROTATIVE LANDING FROM AN ALT OF APRX 800 FT. AN FAA INSPECTOR WHO OBSERVED THE ACCIDENT STATED THE FLT ASCENDED TO APRX 650 FT MSL. AFTER CLOSING THE THROTTLE, THE PLT BEGAN THE MANEUVER. WHILE DESCENDING THROUGH ABOUT 100 FT AGL & HAVING COMPLETED 6-SPINS, THE PLT CONTINUED THE MANEUVER. SUBSEQUENTLY, THE ACFT CONTACTED THE GROUND & WAS DAMAGED. ACCORDING TO THE PLT, THE ACFT SPUN TOO LOW FOR PULL-OUT & HIT THE GROUND.
