Steve,
The crack was probably started quite a while back but took till now to crack far enough to peel the perch away. It happens! Clean the metal with a wire brush, use a narrow grinding disc to make a "ditch" along the entire crack and weld it back together. When welding only weld about an inch at a time. Move to a differant place and do the same. The goal is to not over case harden the whole damage zone which simply create more places for cracks to happen. If possible add a gusset or scab plate. Check the other perches too very close as there is a good possibility there might be more hidden cracks.
Thank you for the advice, Kevin!
