Probable cause
The pilot-in-command's failure to maintain airspeed sufficient to avoid a stall/spin at an altitude insufficient to effect a full recovery.
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 aircraft was engaged in performing aerobatic maneuvers in connection with the experimental aircraft associations convention. The aircraft entered a slow roll to the left. At approximately the inverted position, the aircraft departed controlled flight, entered an uncommanded snap roll (stall/spin), to the left. The aircraft completed three-quarters of the roll, stopped in knife-edge flight and descended approximately 200 to 300 feet into the terrain.
