## Sequence of events

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

- Loss of control - in flight, maneuvering
  - aerobatics - attempted, pilot in command (cause)
  - overconfidence in personal ability, pilot in command (contributing factor)
  - altitude - improper, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

SHORTLY AFTER TAKEOFF AT AN ALT OF APRX 200 FT AGL, THE PLT ATTEMPTED A SNAP-ROLL. THE PLT WAS UNABLE TO RECOVER AFTER THE INTENDED 1 ROLL AND THE MANEUVER CONTINUED FOR 1 1/2 ROLLS. THE PLT WAS ABLE TO LEVEL THE WINGS BUT THE ACFT CONTACTED THE TERRAIN IN A STEEP NOSE DOWN ATTITUDE. THE ACFT THEN BOUNCED INTO THE AIR AND CONTACTED THE GROUND A SECOND TIME IN A TAIL DOWN ATTITUDE WHICH RESULTED IN THE ACFT FLIPPING OVER BACKWARD.
