The airplane landed hard and bounced back into the air. The pilot then added full power in an attempt to execute a go-around. He stated that the airplane failed to climb and drifted off to the left side of the runway until the left wing hit the ground, resulting in the airplane flipping over. The pilot reported that there were no malfunctions with the airplane prior to the accident. ## Factual narrative The pilot reported that during landing and just before touch down the wind shifted to a tailwind.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
