Erik, this is an issue - there shouldn't be cracks there, but it may not be too big a fix. The stringers are hollow members and are tabbed to the sump, but aren't necessarily integral to the hull, so grinding off and replacing the tabbing seems to be the answer. Unfortunately you won't know the extent of this until you start grinding, and it will be a very awkward position to work in.
