## Narrative

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

THE FOLLOWING IS THE PILOT'S STATEMENT OF EVENTS:

"WE TAXIED OUT OF MID ISLAND TO THE WIDE PORTION OF ALPHA IN N2438S. RUN UP WAS UNEVENTFUL AND NORMAL. AS WE STARTED TAXIING TO RUNWAY 6 FOR TAKEOFF I NOTICED THE STUDENT HAVING A BIT OF TROUBLE STAYING IN THE MIDDLE OF THE TAXIWAY. I TOOK CONTROL AND REALIZED THE LEFT BRAKE WAS INOPERATIVE. THERE WAS A PLANE IN FRONT OF US AND THE ONLY THING I COULD DO WAS SHUT THE ENGINE DOWN AND STEP ON THE RIGHT BRAKE CAUSING US TO VEER TO THE RIGHT INTO THE GRASS ON THE SIDE OF THE TAXIWAY. NO ONE WAS HURT AND THERE WAS NO DAMAGE DONE TO PLANE OR AIRPORT PROPERTY."

AFTER THE AIRCRAFT ARRIVED BACK TO MID ISLAND'S HANGAR, THE PILOT WROTE UP THE FOLLOWING SQUAWK: "LEFT BRAKE STOPPED WORKING. VEERED TO THE RIGHT INTO THE GRASS."

INSPECTORS FROM THIS OFFICE CONTACTED THE MECHANIC WHO INSPECTED THE AIRCRAFT AFTER THE INCIDENT OCCURRED. THE FOLLOWING IS A STATEMENT FROM THE MECHANIC WHO CONDUCTED THE INSPECTION:

"TROUBLESHOOTING REVEALED A PROBLEM TO BE FAULTY LH BRAKE MASTER CYLINDER. SINCE AIRCRAFT 100HR INSPECTION WAS COMING DUE, REPAIR WAS ACCOMPLISHED DURING INSPECTION AND IS INCLUDED WITHIN THE 100HR INSPECTION LOG ENTRY."

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.
