Probable cause
The CFI failed 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
The airplane came to rest inverted following a loss of control during a go-around. The purpose of the flight was to practice takeoffs and landings. The certifed flight instructor (CFI) stated the accident occurred on the fourth landing of the flight. The CFI stated the student flew the traffic pattern and was lined up with the runway centerline using a slight crab angle to the right. He stated the airplane began drifting to right during the landing flare. He recalled hearing the student say "runway lights." The CFI stated he called for a go-around and the throttle was advanced to full power. The CFI stated he felt the airplane "mushing" so he pushed the nose forward to maintain airspeed. He stated he anticipated that the nose would lift because they had 30 degrees of flaps extended. He stated the airplane then yawed sharply to the left, hit the ground, and flipped inverted. The CFI stated that during the go-around the airplane required an "inordinate" amount of right rudder to keep the nose straight.

He continued to state that the airplane then yawed sharply to the left, hit the ground, and flipped inverted. The CFI stated he shut off the mixture, fuel selector, magnetos, and master switch prior to exiting the airplane.
