## Sequence of events

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

- Loss of control - in flight, maneuvering
  - supervision - improper, check pilot (cause)
  - aerobatics - performed (contributing factor)
  - aircraft handling - not maintained (cause)
  - stall/spin - not corrected, check pilot
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PURPOSE OF THE FLT WAS FOR ONE INSTRUCTOR PLT (CFI) TO CHECK OUT THE OTHER CFI IN THE ULTRALIGHT VEHICLE. REPORTEDLY, MANY WITNESSES WATCHED AS THE ACFT CLIMBED TO APRX 3000 FT AGL. THE AIRCREW THEN PERFORMED A SERIES OF ROLLS TO THE LEFT & RIGHT. THE ACFT THEN ENTERED A SPIN & CRASHED. NO EVIDENCE OF AN IN-FLT STRUCTURAL FAILURE OR POWER FAILURE WAS FOUND. ACCORDING TO THE OWNER'S MANUAL, AEROBATIC MANEUVERS & INTENTIONAL SPINS WERE PROHIBITED.
