Well Ix, if it’s true the pilot was sacked but the fuel indication system was over-reading for reasons other than pilot error and the pilot had done proper calculations independent of the fuel gauge indications, the pilot is a shoe in for a wrongful dismissal claim.
The only time I believe my fuel gauges is when they read zero.
Water in the fuel has been mentioned as a possible cause of over-reading fuel gauges. I thought pilots did fuel drains to detect water in fuel. Is that not done or doable on a 441?
Maybe the “more to it” is that there was water that should have been but wasn’t discovered and calculations that should have been but weren’t done?
