## Narrative

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

1. AIRCRAFT ^PRIVACY DATA OMITTED^/BUILDER BLED BRAKE SYSTEM BEFORE FLIGHT.

2. AFTER EXITING RUNWAY AT SAN CARLOS, PILOT'S LEFT BRAKE WAS INOPERATIVE. BRAKING ACTION AT TAXI SPEED CAUSED AIRCRAFT TO VEER RIGHT OFF TAXIWAY INTO GRASS. PROP STRUCK SIGN.

3. AFTER INCIDENT, PILOT/BUILDER FOUND RIGHT SIDE RUDDER/BRAKE PEDALS OPERATED NORMALLY, BUT LEFT SIDE LEFT PEDAL WAS DISCONNECTED FROM BRAKE MASTER CYLINDER. THE AN365-1032 NUT FASTENING BRAKE MASTER CYLINDER TO LEFT RUDDER PEDAL HAD FALLEN OFF.

4. PILOT/BUILDER FOUND ROOT CAUSE TO BE IMPROPER TORQUE OF NUT AFTER BRAKE BLEEDING MAINTENANCE OPERATION.

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.
