All, I'm a bit puzzled by some of the fuss over TSO versus non-TSO instruments.
When I wanted to install a non-TSO non-STC EGT gauge (K&S), we figured out the installation (simple, of course), filled out the form 337, got it signed off by the FAA and all was happy. Bill Bayne went into detail about how such installations improve safety. Are people getting such improvements rejected? Or, is the fuss over whether they can be added with just a log book entry with no form 337 being submitted? Ed
