## Narrative

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

DURING LANDING ROLLOUT ON RUNWAY 33 AT ORLANDO APOPKA AIRPORT, LEFT BRAKE OF AIRCRAFT FAILED.  DUE TO LENGTH OF RUNWAY (3,284 FEET), PILOT COULD NOT ROLLOUT TO THE END OF THE RUNWAY WITHOUT APPLYING BRAKES.  SUCH BRAKE APPLICATION CAUSED THE AIRCRAFT TO DEPART THE RIGHT SIDE OF THE RUNWAY NEAR THE END OF THE RUNWAY.  AFTER DEPARTING THE PAVEMENT, THE AIRCRAFT'S NOSE WHEEL ROLLED UP A SMALL EMBANKMENT CAUSING THE TAIL OF THE AIRCRAFT TO CONTACT THE GROUND. SUCH GROUND CONTACT BENT THE LEFT HORIZONTAL STABILIZER, CAUSING SUBSTANTIAL DAMAGE TO THE FRONT AND REAR SPARS OF THE STABILIZER.

DURING A POST ACCIDENT INSPECTION AND SUBSEQUENT DISASSEMBLY OF THE LEFT BRAKE MASTER CYLINDER, OBSERVED BY AN FAA AIRWORTHINESS INSPECTOR, NUMEROUS APPLICATIONS OF BRAKE PRESSURE PRODUCED NORMAL OPERATION, BUT ON INFREQUENT OCCASION, THE BRAKE FLUID WOULD INTERNALLY BY-PASS WITHIN THE BRAKE CYLINDER, CAUSING LOSS OF BRAKE FLUID PRESSURE TO THE LEFT BRAKE CALIPER.  THE CAUSE OF SUCH INFREQUENT BUT INTERMITTENT BRAKE FLUID BY-PASSING CONDITION WAS ATTRIBUTED TO BRAKE SEAL WEAR AND DEBRIS FOUND WITHIN THE BRAKE FLUID RESERVOIR.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.

- [NTSB ERA16LA213](https://openairdocs.org/ntsb/ERA16LA213), Jun 10, 2016: Cessna 310 (N8943Z), Apopka, FL, substantial damage. Probable cause: The intermittent failure of the left brake master cylinder, which resulted in asymmetric braking and the subsequent loss of directional control during the landing roll.

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.
