## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

INCIDENT OCCURRED ON LANDING ROLLOUT. WEATHER WAS CLEAR WITH UNRESTRICTED VISIBILITY. ON INITIAL BRAKING, A “POP” WAS FELT THROUGH THE LEFT BRAKE PEDAL DURING THE LANDING ROLL. RIGHT BRAKE PRESSURE HAD TO BE RELEASED TO PREVENT TURNING TO THE RIGHT AT SPEED. A SECOND APPLICATION CHECK OF THE LEFT BRAKE HAD NO EFFECT.

THE AIRCRAFT HAS A CASTERING NOSE WHEEL AND REQUIRES DIFFERENTIAL BRAKING TO CONTROL STEERING, SO WITHOUT EQUAL BRAKING ONLY PARTIAL RIGHT BRAKE COULD BE USED TO SLOW THE AIRCRAFT TO PREVENT A MORE EXTREME TURN TO THE RIGHT. GIVEN THE LACK OF BRAKING AND STEERING CONTROL, THE AIRCRAFT DEPARTED THE RUNWAY AT THE

DEPARTURE END OF THE RUNWAY WHILE STILL TRAVELING APPROXIMATELY ~30 KTS. DURING THE RUNWAY OVERRUN, RIGHT BRAKE WAS USED TO AVOID DIRECT IMPACT WITH AIRPORT SIGNAGE, BUT THE RIGHT WING IMPACTED A RUNWAY END LIGHT RESULTING IN VISIBLE DAMAGE TO THE COMPOSITE SKIN ON THE UNDERSIDE OF THE RIGHT WING. ONCE THE SPEED HAD DECREASED TO LESS THAN 15 KTS, FULL RIGHT BRAKE WAS APPLIED TO SPIN THE AIRCRAFT TWICE IN A CIRCLE UNTIL IT STOPPED, AVOIDING IMPACT WITH THE AIRPORT FENCING.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
