What was found
(CAN) THE ENGINE WAS SENT FOR INVESTIGATION AFTER THE REDUCTION GEARBOX WAS FOUND WITH METAL CONTAMINATION. DISASSEMBLY FOUND THE CAUSE OF THE CONTAMINATION WAS THE SPALLING OF THE #15 BEARING. HIGH MAGNETISM ON SEVERAL COMPONENTS AND ELECTRICAL PITTING ON THE #15 AND #19 BEARINGS INDICATE THE ENGINE EXPERIENCED A LIGHTNING STRIKE. THE FAILURE OF THE #15 BEARING IS THOUGHT TO HAVE BEEN INITIATED BY THE LIGHTNING STRIKE.
