What happened
Following the completion of airwork, a flight instructor and a student pilot returned to the airport traffic pattern. The aircraft transitioned through the base leg and onto final approach with 20 degrees of flaps extended. At the time, the wind was reported as a direct crosswind from the right at 4 knots.
During the landing sequence, the instructor noted that the aircraft flared slightly high and maintained a speed that appeared slightly fast. While holding the pitch attitude, the airplane began to descend at a higher rate than anticipated. In response, the instructor applied partial then full power to initiate a go-around while maintaining the established pitch.
During this maneuver, the flight controls became sluggish. The instructor relaxed back pressure on the controls, causing the aircraft to bank to the left. This bank was not corrected using full right aileron and rudder input. Consequently, the left wingtip made contact with the runway. The impact caused the airplane to rotate approximately 180 degrees before coming to rest in an upright position. Both occupants were not injured.
