On September 21, 2002, at 1715 eastern daylight time, a Cessna 172S, N784SA, sustained substantial damage to the engine firewall during a hard landing at Boyne Mountain Airport (BFA), Boyne Falls, Michigan. The private pilot and one passenger were not injured. The Title 14 CFR Part 91 personal flight departed Tulip City Airport (BIV), Holland, Michigan, at 1530, and was making a full stop landing at BFA. Visual meteorological conditions prevailed and no flight plan was filed. The pilot reported he landed on the center of runway 35 (5,200 feet by 60 feet, asphalt) about 800 feet from the beginning of the runway. He reported, "I did not feel or hear any striking of the prop on the runway. I felt that I simply flared too high, floated, and landed hard. I bounced once, added a little power, and landed properly. It was not until later that it was discovered the propeller tip was bent and that the nose wheel probably was the first to hit the runway."
