What was found
FOUND LOWER LEG AT KNEE JOINT CRACKED ALONG THE CASTING LINE AT THE MOUNTING SWIVEL PIN ATTACHMENT AND THE LEG WAS SEPARATING AT THE CRACKED AREA. ANOTHER LEG WAS CHECKED TO BE USED AS A REPLACEMENT, BUT ALSO WAS FOUND CRACKED. THE CRACKS IN THE CASTING APPEAR TO START FROM THE INSIDE-OUT AND WILL NOT SHOW ANY DEFECTS UNTIL THE CASTING HAS BROKEN.
