The student pilot completed three takeoffs and landing with the certified flight instructor (CFI) on board, then took off for his first solo flight in the pattern. During the first landing, the airplane bounced twice and on the third touchdown, the nose gear collapsed and the airplane slid to a stop. The student pilot was not injured, but the airplane sustained substantial damage to the firewall. There were no reports of preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
