The NTSB's narrative final · quoted from the NTSB record
THE PILOT REPORTED THAT THE APPROACH AND LANDING TO TOUCHDOWN WERE NORMAL. AT TOUCHDOWN, THE AIRCRAFT SHUTTERED AND PULLED TO THE RIGHT, BUT WAS KEPT ON THE RUNWAY THROUGH THE USE OF LEFT BRAKE AND NOSEWHEEL STEERING. AFTER CONTINUING DOWN THE RUNWAY FOR ABOUT 1500 FT, THE AIRCRAFT SLOWED TO APPROXIMATELY 10 MPH, THEN YAWED VIOLENTLY TO THE RIGHT AND SKIDDED WITH THE LEFT WING FORWARD. THE LEFT MAIN GEAR COLLAPSED AS THE AIRCRAFT CAME TO A HALT. WHEN EXAMINED, THE RIGHT WHEEL WOULD ROTATE SLOWER THAN THE LEFT WHEN BOTH WERE ROTATED TOGETHER, BUT NEITHER LOCKED UP. WHILE THE RIGHT WHEEL WAS BEING TURNED, A BRAKE PUCK FELL OUT OF THE BRAKE ASSEMBLY. A DISASSEMBLY OF THE BRAKE REVEALED A SECOND PUCK WAS ALSO LOOSE. AFTER REASSEMBLY, THE RIGHT BRAKE OPERATED NORMALLY.
