## Analysis

The student pilot reported that he was performing touch-and-go landings. When he added power to take off, he lost control of the airplane as it veered left. He was unable to regain control before the airplane impacted a snowbank. The airplane flipped over and came to rest inverted on the side of the runway, which resulted in substantial damage to the wings, fuselage, and vertical stabilizer. The pilot reported there were no mechanical malfunctions or failures that would have precluded normal operations. At the time of the accident, the pilot was landing on Runway 34 with wind from 350°at 4 knots.
