## Analysis

THE PLT WAS ADVISED THAT HE WAS CLEARED FOR AN INTERSECTION TAKEOFF ON RWY 17R. AFTER HIS RUN UP, THE PLT ATTEMPTED A NIGHT TAKEOFF TO THE NORTH ON AN UNLIGHTED TAXIWAY THAT RAN PARALLEL TO THE ACTIVE RUNWAY. CONTROLLERS ADVISED THE PILOT TO ABORT, WHICH HE DID, HOWEVER, HE WAS UNABLE TO STOP THE ACFT PRIOR TO RUNNING OFF THE END OF THE TAXIWAY. PLT STATED THAT HE HAD NOT APPLIED FULL BRAKING AS THE TAXIWAY WAS NOT LIT AND HIS LANDING LIGHT WAS INOP AND AS A RESULT HE COULD NOT SEE HOW MUCH TAXIWAY REMAINED. HE CITED HIS LACK OF FAMILIARITY WITH THE AIRPORT AS BEING THE REASON HE ATTEMPTED TO DEPART ON THE TAXIWAY. HE DID NOT EXPLAIN WHY HE ATTEMPTED TO DEPART TO THE NORTH WHEN HE WAS CLEARED TO SOUTH ON RUNWAY 17R.
