The NTSB's narrative final · quoted from the NTSB record

According to the student pilot, he completed a stabilized approach to the runway, with the airspeed 5 knots higher than the prescribed approach speed due to the 8 knot headwind condition. During the landing flare, the airplane encountered a gust of wind, and bounced on the runway. He said he added power to slow the descent, but the airplane ballooned again with some drift to the left. He decided to execute a go around, and as he applied full power without adding rudder, the airplane veered to the left and departed the left side of the runway. He then reduced the power in an attempt to regain directional control of the airplane, but it continued forward until the nose gear collapsed and the airplane came to rest in a grassy area to the left of the runway. During the accident sequence, the airplane incurred substantial damage to the firewall and left wing. The student pilot reported there were no mechanical anomalies with the airplane. The wind reported at the airport about the time of the accident was from 150 degrees at 8 knots.
