## Discrepancy

ALL LIGHTING WAS FOUND TO BE OPERATIVE WITH NO EVIDENCE OF BURNING ODOR. MAINTENANCE INSPECTED COCKPIT INSTRUMENT AND CB PANEL LIGHTING WIRING AND FOUND A BUTT SPLICE POWERING ONE CB PANEL BACKLIGHTING THAT APPEARED CHARRED. SPLICE WAS REPLACED AND THE PANEL TESTED WITH NO OTHER ANOMALIES FOUND. AIRCRAFT WAS RETURNED TO SERVICE.
