The NTSB's narrative final · quoted from the NTSB record

The pilot reported that the landing was uneventful, however, during the landing roll a sudden gust of wind from the right pushed the aircraft toward the left side of the runway and the "Welcome to Bandera" sign. The aircraft struck the sign, and shortly after the aircraft came to rest, the pilot heard a "whoomp" sound followed by the start of a fire. The pilot released his seatbelt and exited the aircraft sustaining serious burns to his lower legs and feet. The aircraft was then consumed by the fire. The pilot reported that he believed that the fuel tank was ruptured when he collided with the sign and traveled over the rough terrain which splattered fuel onto the hot section of the engine.
