Probable cause

Failure of the pilot to maintain adequate airspeed during the go-around, which resulted in an inadvertent stall.

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

After initiating a go-around from a VFR approach to land, the experimental custom built aircraft entered a descent & crashed. Subsequent inspection of the aircraft failed to reveal any anomaly that would have contributed to the event.
