Incident Description
During a solo flight practicing touch-and-go landings, a student pilot experienced a loss of control following a hard landing. The flight instructor, supervising from the ramp, observed the sequence of events and noted that the first touch-and-go was performed adequately.
On the second approach, the instructor saw the student flare improperly, prompting the student to execute a go-around before touching down. During the third touch-and-go, the student flared improperly again. Upon touchdown, the aircraft began to porpoise. As the porpoising continued, the propeller struck the ground, and the nose landing gear collapsed.
Sequence of Events
The student pilot was unable to recover control after the porpoise developed. The aircraft sustained damage from the propeller strike and collapsed nose landing gear. No further details about the aircraft or location were provided in the available information.
