He stated that he landed too fast and the airplane bounced on touchdown. He attempted to recover the landing, but the airplane began to porpoise. The pilot reported the airplane porpoised several times prior to the nose gear collapsing and the airplane coming to rest on the runway. ## Factual narrative On August 14, 2008, at 0910 eastern daylight time, a Cessna 172R, N21SZ, collided with runway 21R (3,802 feet long by 100 feet wide, asphalt) following a loss of control while landing at the Cincinnati Municipal-Lunken Airport (LUK), Cincinnati, Ohio.
