Factual narrative

THE PLT WAS TAKING PART IN AN AIRSHOW WITH A PERSON STANDING ON THE LEFT WING. THE PLT SAID THAT WHEN BRAKES WERE APPLIED DURING LANDING ROLL, THE RIGHT BRAKE OPERATED PROPERLY, BUT THE LEFT BRAKE FAILED. THE PLANE THEN TURNED RIGHT AND DEPARTED THE RUNWAY, RESULTING IN A GROUND LOOP. THE LEFT WING STRUCK THE GROUND AND BOTH LEFT WINGS WERE BENT. THE PERSON, WHO WAS STANDING ON THE LEFT LOWER WING, WAS THROWN CLEAR. A POST-ACDNT EXAM REVEALED THAT 3 OF THE 4 BRAKE PADS WERE MISSING FROM THE LEFT BRAKE.
