What was found
MOUNT WAS FOUND BROKEN IN 2 PLACES; BOTH OUTBOARD AND BELOW THE UPPER LEFT MOUNTING FLANGE. A SMALL AMOUNT OF INTERNAL CORROSION WAS DETECTED, BUT IT DID NOT APPEAR TO BE A CONTRIBUTING FACTOR. THE BROKEN AREAS WERE NOT ON WELD JOINTS, IT APPEARS THAT THE SUPPORT TUBE ASSEMBLIES FAILED.
