The issue isn't specifically what failed. The issue is that the failure in this case was both predictable and ignored. PG&E willfully failed to inspect/maintain the equipment. Accidents happen and you can't control for everything. But this is a very clear and obvious failure. The failure isn't specific to what failed in this case (The c-hook) but the failure of PG&E to do any due diligence.
