Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The ultralight pilot had been practicing maneuvers that weredescribed as whip stalls which were not taught or authorizedbecause of the excessive 'g' forces imposed. An instructor checked his machine and warned him of the dangers on the day of the accident. The plt said he understood and would 'watch it'. Later that day he practiced similar maneuvers again and the left wing folded from negative g forces. This machine is limited to 3 negative 'g's'. The vehicle fell from about 350 ft in a vertical uncontrolled descent after the wing failed.
