THE APPROXIMATE DAMAGE DIMENSIONS ARE AS FOLLOWS: .25" DIAMETER TO A MAXIMUM DEPTH OF 100 PERCENT MATERIAL LOSS AND .468" DIAMETER TO A MAXIMUM DEPTH OF 100 PERCENT MATERIAL LOSS.  ACCOMPLISHMENT OF THIS PERMANENT TRACK SPLICE REPAIR WILL BE IAW ETD2016-170-058871A AND SRM PART II 53-00-10, FIGURE 205.
