Tail boom Crack

I am enclosing photos of a upper tail boom attachment fitting and airframe deck & tail boom support beam. The Fitting was not damaged. The crack was discovered from the top side with the cowling removed. I recommend polishing the sharp edge of the V channel to reduce the stresses created by the slight nicks often found there.
