even a clock not working can be a legal no go for IFR
With that list of problems I'd be going somewhere else to find an aircraft to fly. If the standards are so low who knows what else is not working.
"Developing minor structural issue" Who said it's minor? Is there such a thing as a minor structural issue?
Accidents often happen from a couple of issues on top of each other. If fuel pressure indication is unreliable or not working, then the engine starts messing about will you know if its fuel pressure related or not? You may well waste time you don't have thinking about it.
I think you're right it should have been fixed hundreds of hours ago, if its been broke for that long.
Just go fly a properly maintined plane. (well thats my humble £0.02 worth)
