I thought Lycoming was charging back for bad cranks and cams?

Any overhauler is going to deny the core charge if the parts are unrepairable.

IIRC the big deal with Lyc a while ago was that they changed their policy on
cases. Field-welded cases had always been acceptable, but they changed their
policy without notice so that they denied the core charge on cases that had ever
been welded.

Given the age of our engines, a lot of them have had welded cases at one time or
another.

I don't know whether field-overhaul shops are still accepting welded cases, or
if they've followed Lycoming's lead.
