## Discrepancy

SMOKE DEVELOPED FROM BEHIND COCKPIT OVERHEAD PANEL AFTER TURNING ON ENGINE ANTI-ICE WHILE CRUISING AT FL 240 EN ROUTE FROM EWR TO CAE. THE SMOKE CEASED WHEN ANTI-ICE WAS TURNED OFF. THE FLIGHT WAS CONTINUED TO CAE WHERE IT LANDED WITHOUT FURTHER PROBLEMS.  MAINTENANCE FOUND BURNT WIRING TO ANTI-ICE MODULE AND AFT OF ANTI-ICE MODULE IN THE COCKPIT OVERHEAD PANEL. THE BURNT WIRING WAS REPLACED.  IN ADDITION, THE C146 CIRCUIT BREAKER AND ANTI-ICE VALVE WERE REPLACED.  OPERATIONAL CHECKS OF THE SYSTEM WERE GOOD WITH NO OTHER DEFECTS FOUND.
