As to the points you keep raising, with any of those items, at an outstation, I would phone home and there would be a local other airline or engineering service engineer who will be arranged to come and view the problem. A small delay- still cheaper than what I think your desired 'cure' would be. For those defects and no local engineer present, a big delay. Still cheaper! I rather like being alive myself- I can't imagine ever wanting to 'take a chance' on that list of items. I think you are using ridiculous scare tactics.
