On October 27, 1994, at 0957 hours Pacific daylight time, a Cessna 152, N64851, sustained a hard landing on runway 26L at Brackett Airport, La Verne, California. The student pilot was practicing solo touch-and-go takeoffs and landings. The airplane, operated by Cable Air, Upland, California, sustained substantial damage. The student pilot was not injured. Visual meteorological conditions prevailed. The flight originated at Cable Airport, Upland, California, at 0930 hours. The student's instructor reported in the aircraft accident report that the airplane ballooned on the initial touchdown and became airborne. The instructor said that during the recovery the student failed to hold the airplane's nose up and the airplane began to porpoise. The student applied power to execute a go-around, but accidently pushed the control wheel forward, which caused the nose to pitch down. The nose wheel collapsed when it struck the runway in a nose-down attitude.
