## Discrepancy

AFTER TURNING ON TAXI LIGHT, A STRONG ELECTRICAL BURNING ODOR WAS NOTICED, WITH THE CIRCUIT BREAKER HOT TO THE TOUCH.  FURTHER INSPECTION REVEALED A BURN MARK ON THE SIDE OF TAXI LIGHT CIRCUIT BREAKER.  AD 2008-13-17 HAD BEEN COMPLETED 691 FLIGHT HOURS PREVIOUSLY.  INTERNAL FAILURE IS BELIEVED TO BE THE CAUSE.  NO RECOMMENDATIONS AT THIS TIME.
