Everything installed needs to function in order for the aircraft to be considered airworthy. For an item that doesn't function and you don't want to fix it, that item can be deferred or removed to maintain airworthiness provided it is not a required item for the type of operation you fly. How this is handled will be up to the IA that signs your annual.
LOL Good one, Salty.
I cannot recall my IA checking my EGT gauge either. That would be fun if he grounded me due to a bad probe or something.
It is a good question. If the owner placards the non-required gauge INOP, the airplane remains airworthy. IA cannot change that.
In general that is correct plus the extra Bob mentioned above. However, the original EGT deferment ends at the annual or next scheduled inspection. Everything needs to function at that time. So you are looking at fixing, removing. or deferring again. How the IA handles it in this case is up to him. But in most cases the IA will sign the annual with discrepancies (EGT inop) which will require another deferment sign-off by an A&P or if applicable the owner. Nothing can stay deferred indefinitely on a single write up.
They didn't "get around the issue." The annual was signed with an inop item. As I've mentioned before, it's up to the IA how he handles things. And while it's his certificate and signature on the annual, the owner is caught in the middle as he still is responsible for the overall airworthiness.
No, only the old CHT is required unless you spring for the more expensive JPI which is your primary display. I had my old EGT removed during my JPI730 install, but kept the ye-olde CHT.
