What was found
DURING INSPECTION OF ENGINE MOUNT AFTER ENGINE REMOVAL FOR OVERHAUL, CRACKS WERE FOUND AT BOTH FORWARD ENGINE MOUNTING BRACKET LOCATIONS. SUSPECT THAT CRACKS ARE DUE TO FATIGUE. CRACKS ARE DIFFICULT TO SEE WITH THE ENGINE INSTALLED DUE TO THE CLOSE PROXIMITY OF THE RUBBER MOUNTING PADS. RECOMMEND CLOSE INSPECTION OF THIS AREA AT ANNUAL INSPECTIONS.
