What was found
ACCOMPLISHED A MODIFICATION TO THE POWER DISTRIBUTION PANEL TO SUPPORT AN AVIONICS MOD. THE SYSTEM WAS CHECKED OK AND INSPECTED THE TERMINAL STUD FOR SECURITY. THE STUD WAS TIGHT AND THE CONNECTION WAS SECURE. AFTER DELIVERY THE AC HAD ELECTRICAL PROBLEMS. IT WAS FOUND TO HAVE A BURNED SPOT WHERE THE NEW WIRE WAS INSTALLED AND THE STUD WAS SOOSE. REMOVED THE PANEL AND HAD IT REPAIRED AND REINSTALLED TO RETURN THE AIRCRAFT TO SERVICE. SUGGESTED THAT SB 31-245 SHOULD BE ACCOMPLISHED BUT THE CUSTOMER DECLINED. RECOMMEND AD NOTE BE WRITTEN TO MAKE SB 31-245 MANDATORY. THIS HAS HAPPENED BEFORE. (CE09200403890)
