How hard can it be to do a final inspection before sealing up a closed compartment? It must be intentional.
Hey in general construction I couldn’t close a wall until the framing, wiring and any other services were inspected so I find it hard to believe that something so much more critical like an aircraft doesn’t require a final inspection before sealing an are up, people need to be fired.
That has to be a part of the routine. Which means, those who did the final inspection/walk through should be the first to be scrutinized and debriefed.
