On June 21, 1998, at 1430 central daylight time, a Cessna 172, N99548, sustained substantial damage on impact with the terrain and nose over during a landing on runway 9 (3,270' X 40' dry/asphalt), at Campbell Airport near Grayslake, Illinois. The student pilot reported minor injuries. The airplane was being operated as a personal flight under 14 CFR Part 91 when the accident occurred. The pilot said his flare was high. He said on initial touchdown the airplane bounced and he lost control. The flight originated in Wheeling, Illinois at 1355. Visual meteorological conditions prevailed at the time and no flight plan was filed. The pilot reported on his second approach his flare was too high, but he did not correct it. The airplane bounced with the airplane veering to the left. He said he may have applied power while maintaining back pressure on the yoke. He said the airplane rolled into a soft area north of the runway and nosed over. An inspection of the airplane subsequent to the accident did not reveal any pre-accident anomalies..
