The student then completed three more touch-and-go landings, but on the final landing, the airplane touched down nose first and then bounced. She attempted to go around, but the airplane bounced again, and the propeller struck the runway. She maneuvered the airplane back to the ramp without further incident. The airplane sustained substantial damage to the engine mount frame, mounts, and nose landing gear tunnel. The student reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Factual narrative The solo student pilot reported that, after completing touch and go maneuvers in the pattern with her flight instructor, the flight instructor deplaned.
