Narrative:

Upon application of power on takeoff roll, the aircraft veered left. The captain immediately reduced power and aborted the takeoff. He was then able to regain steering authority/authorized of the aircraft. Tower was notified of the abort. We exited the runway. All system checked out normally so we took off and the flight was uneventful. Callback conversation with reporter revealed the following information: the reporter stated there was a momentary nosewheel steering light at power application. The light should have been out. There also were gusty winds. The captain at first thought a wind gust caused the swerve until the first officer said the nosewheel steering light was on momentarily. There is good company maintenance at cvg. Not taking the airplane back to the gate was due only to the fact the airplane seemed to steer well enough. There was no light to indicate anything was wrong. The crew had the airplane for at least another leg without any further abnormal problem. The reporter was satisfied there was just a momentary sticking switch.

Title: WITH PWR APPLICATION FOR TKOF THE ACFT VEERS TO THE L AND THE PF ABORTS THE TKOF. THE FLC DID NOT RETURN TO THE GATE TO HAVE MAINT DIAGNOSE THE PROB.

Narrative: UPON APPLICATION OF PWR ON TKOF ROLL, THE ACFT VEERED L. THE CAPT IMMEDIATELY REDUCED PWR AND ABORTED THE TKOF. HE WAS THEN ABLE TO REGAIN STEERING AUTH OF THE ACFT. TWR WAS NOTIFIED OF THE ABORT. WE EXITED THE RWY. ALL SYS CHKED OUT NORMALLY SO WE TOOK OFF AND THE FLT WAS UNEVENTFUL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THERE WAS A MOMENTARY NOSEWHEEL STEERING LIGHT AT PWR APPLICATION. THE LIGHT SHOULD HAVE BEEN OUT. THERE ALSO WERE GUSTY WINDS. THE CAPT AT FIRST THOUGHT A WIND GUST CAUSED THE SWERVE UNTIL THE FO SAID THE NOSEWHEEL STEERING LIGHT WAS ON MOMENTARILY. THERE IS GOOD COMPANY MAINT AT CVG. NOT TAKING THE AIRPLANE BACK TO THE GATE WAS DUE ONLY TO THE FACT THE AIRPLANE SEEMED TO STEER WELL ENOUGH. THERE WAS NO LIGHT TO INDICATE ANYTHING WAS WRONG.
