According to the pilot, the airplane bounced during the landing. He added power in an attempt to recover, but then decided to perform a go-around maneuver. He performed the go-around checklist; however, he inadvertently retracted the flaps to the zero degree, or "UP" position, instead of the required 20 degree flap position. The airplane settled onto the grass to the left of the runway and struck bushes and cement blocks located about 150 feet off the runway, which resulted in substantial damage to the horizontal stabilizer. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
