What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
During second full stop landing attempt of first solo flight, student pilot lost directional control of aircraft on rollout after touchdown. The aircraft propeller struck the runway pavement and subsequently struck a taxiway sign upon the aircraft's departure from the runway. The student pilot was not injured and damage to the aircraft was limited to the propeller, with additional damage potentially being caused to internal engine components.
