What was found
PILOT REPORTED THE NR 2 ALTERNATOR WAS INTERMITTENT. WHILE TROUBLESHOOTING THE NR 2 ALTERNATOR, FOUND 13 SCREWS LOOSE AND 1 SCREW MISSING ON THE COPPER CIRCUIT BREAKER BUSS BAR. THE 1 SCREW MISSING WAS ON THE NR 2 ALTERNATOR CIRCUIT BREAKER BUSS FEED. PROBABLE CAUSE FOR THIS WOULD BE THAT THEY WERE NOT TIGHT FROM FACTORY. RECOMMEND CHECKING TORQUE OF ALL CIRCUIT BREAKER SCREWS AT NEXT MAINTENANCE ACTION. (K)
