Narrative:
On touchdown, aircraft began to drift to the right side of runway. PIC attempted to counter with nosewheel steering. As we started to get close to the right side of runway we reviewed a message on the panel 'nosewheel steering failure.' to stop the drift PIC used differential braking. The aircraft then turned hard left and came to a stop 90 degrees left of centerline. There was no damage to the aircraft except a small scrape on the right main landing gear fairing door. I believe that we hit a runway light. Callback conversation with reporter revealed the following information: the reporter stated the gulfstream nosewheel steering is all electronic with nosewheel speed sensing and computer controled operation that has a high failure rate. The reporter said the failure was not found and all components were removed and sent to gulfstream. The reporter stated the only clue to the failure was a wheel speed sensing fault in the computer self test. The reporter said the FAA has expressed interest in this incident.

Title: A GULFSTREAM IV ON LNDG ROLL ACFT DRIFTED TO THE R WITH 'NOSEWHEEL FAILURE' WARNING ILLUMINATED. USED BRAKING. ACFT STOPPED 90 DEGS TO RWY CTRLINE.
Narrative: ON TOUCHDOWN, ACFT BEGAN TO DRIFT TO THE R SIDE OF RWY. PIC ATTEMPTED TO COUNTER WITH NOSEWHEEL STEERING. AS WE STARTED TO GET CLOSE TO THE R SIDE OF RWY WE REVIEWED A MESSAGE ON THE PANEL 'NOSEWHEEL STEERING FAILURE.' TO STOP THE DRIFT PIC USED DIFFERENTIAL BRAKING. THE ACFT THEN TURNED HARD L AND CAME TO A STOP 90 DEGS L OF CTRLINE. THERE WAS NO DAMAGE TO THE ACFT EXCEPT A SMALL SCRAPE ON THE R MAIN LNDG GEAR FAIRING DOOR. I BELIEVE THAT WE HIT A RWY LIGHT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE GULFSTREAM NOSEWHEEL STEERING IS ALL ELECTRONIC WITH NOSEWHEEL SPD SENSING AND COMPUTER CTLED OP THAT HAS A HIGH FAILURE RATE. THE RPTR SAID THE FAILURE WAS NOT FOUND AND ALL COMPONENTS WERE REMOVED AND SENT TO GULFSTREAM. THE RPTR STATED THE ONLY CLUE TO THE FAILURE WAS A WHEEL SPD SENSING FAULT IN THE COMPUTER SELF TEST. THE RPTR SAID THE FAA HAS EXPRESSED INTEREST IN THIS INCIDENT.
