When power was applied, the airplane yawed to the left, struck a runway remaining sign, and bounced off the ground. The flight instructor moved the throttle to idle, and the airplane settled to the ground and rolled onto runway 30 center and then stopped. The airplane sustained substantial damage to the aft fuselage bulkhead and horizontal stabilizer. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The operator reported that during a training flight, the flight instructor attempted a go-around on runway 30 right.
