## Discrepancy

(CAN) THE ENGINE, WHICH WAS MAKING METAL, WAS SENT FOR INVESTIGATION/OVERHAUL. DISASSEMBLY FOUND THE #19 BEARING IN THE REDUCTION GEARBOX SPALLED ON THE INNER RACE. THIS IS THE CAUSE OF THE RGB MAKING METAL. THERE WERE NO CONTRIBUTING FACTORS FOR THE #19 BEARING SPALLING, THEREFORE THIS IS CONSIDERED TO BE A PRIMARY FAILURE OF THE #19 BEARING. THE BEARING WAS REPLACED.
