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
During a local pleasure flight, the aircraft was observed to make a climbing right turn to the inverted position. When observed a few seconds later, the aircraft was right side up in a shallow spin. The aircraft remained in this position until colliding with the terrain. Inspection of the wreckage revealed no sign of fuel in the fuel tanks or around the wreckage site.
