On June 23, 2005, about 1700 eastern daylight time, a Cessna 152, N46541, was substantially damaged while landing at Greenville Municipal Airport (4G1), Greenville, Pennsylvania. The student pilot was not injured. Visual meteorological conditions prevailed, and no flight plan was filed for the solo instructional flight conducted under 14 CFR Part 91. The student pilot stated that he departed 4G1 about 1630, to practice takeoffs and landings. The student pilot completed three "touch and go's" to runway 33, a 2,703-foot-long, 75-foot-wide, asphalt runway. During the flare for the fourth landing, the student pilot "overcontrolled and ballooned up." The student pilot then applied forward force to the yoke, and the airplane bounced on the runway twice, collapsing the nose gear. The airplane came to rest on the runway, and sustained substantial damage. The student pilot reported that the wind was light and variable at the time of the accident.
