## Sequence of events

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

- Airframe/component/system failure/malfunction, maneuvering
  - stall - performed, pilot in command
  - wing - overload
  - design stress limits of aircraft - exceeded, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

SEVERAL WITNESSES OBSERVED THE ULTRALIGHT VEHICLE FLYING IN A SOUTHWESTERLY DIRECTION AT ABOUT 1500 FT AGL. THEY REPORTED THAT THE PLT HAD EXECUTED 5 OR 6 STALL MANEUVERS, FOLLOWED BY NORMAL STRAIGHT AHEAD RECOVERIES. DURING THE LAST STALL, THE ACFT WAS OBSERVED IN A STEEPER THAN NORMAL CLIMB ANGLE, THEN FELL OFF AT THE TOP OF THE MANEUVER & ENTER A DIVE IN A SLIGHTLY INVERTED ATTITUDE. MOMENTS LATER, THE WINGS FOLDED & THE ULTRALIGHT CRASHED. AN INVESTIGATION REVEALED THAT THE UPPER KING POST HAD COLLAPSED. THERE WAS EVIDENCE THE FAILURE OCCURRED WHEN NEGATIVE AERODYNAMIC LOADS WERE ENCOUNTERED.
