THE PILOT REPORTED THAT DURING POST LANDING TAXI OPERATIONS, HE WAS UNABLE TO STEER THE AIRPLANE OR APPLY NORMAL BRAKES. THE AIRPLANE DEPARTED THE TAXIWAY, AND RAN ACROSS A GRASS MEDIAN AND SERVICE ROAD BEFORE IT IMPACTED A LIGHT POLE AND CAME TO A STOP. POST ACCIDENT INVESTIGATION REVEALED A FAILED NOSEWHEEL STEERING HYDRAULIC LINE, WHICH ALLOWED SYSTEM FLUID TO BE PORTED OVERBOARD INTO THE NOSE WHEELWELL. FURTHER EXAMINATION REVEALED THE LINE FAILED AS A RESULT OF A PUNCTURE OF THE INTERNAL HOSE BY THE WORN/FRAYED OUTER BRAID. RECORDS INDICATE THE FAILED LINE WAS ORIGINAL EQUIPMENT AND HAD OPERATED THROUGH 17,969 HOURS AND 21,324 CYCLES.
