The student pilot said he was on final approach for landing on runway 12 at 20U when he encountered a crosswind from the northeast. He corrected for the crosswind and proceeded to land. The airplane ballooned, touched down, and pulled to the right. The student pilot applied full power in an attempt to abort the landing. The airplane went off the right side of the runway, became airborne, and struck a large hay bale. Post-accident examination revealed the firewall was buckled, both wing leading edges were crushed, the nose landing gear was sheared off, and there was some damage to the empennage.
