## Discrepancy

THE AIRCRAFT LANDED ON RUNWAY 20R AT KSNA UNDER VISUAL METEOROLOGICAL CONDITIONS. NORMAL BRAKING WAS AVAILABLE DURING THE LANDING ROLL USING THE PRIMARY HYDRAULIC BRAKING SYSTEM.

THE AIRCRAFT EXITED THE RUNWAY AT TAXIWAY ECHO AND TURNED LEFT ONTO TAXIWAY ALPHA. IMMEDIATELY AFTER THE TURN ONTO TAXIWAY ALPHA, THE “PWR BRK LOW PRESS” ANNUNCIATOR ILLUMINATED, AND A COMPLETE LOSS OF PRIMARY HYDRAULIC BRAKING WAS OBSERVED.

THE BACKUP BRAKING SYSTEM (PNEUMATIC NITROGEN) WAS IMMEDIATELY SELECTED AND USED TO ARREST FORWARD MOTION. TO ENSURE THE AIRCRAFT CAME TO A COMPLETE STOP AND TO PREVENT FURTHER MOVEMENT, BOTH ENGINES WERE SUBSEQUENTLY SHUT DOWN. ALL EXTERIOR LIGHTS WERE LEFT ON.

KSNA GROUND CONTROL WAS ADVISED THAT THE AIRCRAFT HAD LOST PRIMARY BRAKING, WAS OPERATING ON THE BACKUP BRAKING SYSTEM ONLY, AND WOULD REQUIRE TOWING ASSISTANCE TO THE RAMP.

APPROXIMATELY 10 MINUTES LATER, ACI NORTH ARRIVED, AND THE AIRCRAFT WAS SECURELY ATTACHED TO THE TUG. AFTER THE AIRCRAFT WAS ATTACHED TO THE TUG, PASSENGERS WERE ADVISED OF A BRAKING SYSTEM MALFUNCTION AND INFORMED THAT THE AIRCRAFT WOULD BE TOWED TO THE RAMP, RESULTING IN A SLIGHT DELAY TO ARRIVAL.

THE AIRCRAFT WAS TOWED TO THE RAMP WITHOUT FURTHER INCIDENT. NO INJURIES OCCURRED.

CREW ACTIONS

EMPLOYED BACKUP PNEUMATIC BRAKING SYSTEM
SHUT DOWN BOTH ENGINES TO PREVENT UNINTENDED MOVEMENT
NOTIFIED GROUND CONTROL IMMEDIATELY
