Aircraft maintenence is regulated by federal aviation authorities, in accordance with manufacturer guidelines. It’s incredibly regulated, and transparent.

Run to failure isn’t a thing in aviation.

I like your approach, and for what it’s worth, I live in about a half km from the aberfoyle bottling plant, and am on well water from the same aquifer as the plant. I’ve never once had well issues, or low water.

I’m in no way trying to “carry water” for a terrible company like Nestle, however the impact on the local populations water supply is minimal, and the community benefits from tax dollars that keep our property costs relatively low and our community centres and parks well maintained.

Again, fuck nestle and their more nefarious business practices, but there is some nuance to the discussion.
