The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Pilot made an immediate landing on RUNWAY15 at which time the pilot noticed a large part of the propeller blade was missing and smoke was entering the cabin. The pilot and student evacuated the aircraft and observed that the engine compartment was in flames. Fire was extinguished by airport personnel. The seperated propeller blade penetrated the lower engine cowling damaging the engine intake and exhaust system, alternator mount and carburator air box causing the fire.
