## Discrepancy

DURING A 50/100HR ENGINE INSPECTION, NOTICED THAT A SCREW ATTACHED TO SAFETY WIRE WAS STICKING OUT BETWEEN THE BACK SIDE OF THE ENGINE BAFFLE AND FWD SIDE OF THE ALTERNATOR, UPON FURTHER INSPECTION, FOUND THAT SCREW HAD BEEN PULLED OUT OF THE CASING AND THAT THE OTHER 3 SCREWS THAT ATTACH THE COOLING BLAST TUBE WERE VERY LOOSE. SCREWS CANNOT BE REINSTALLED. ALTERNATOR MUST BE REPLACED
