I recently watched the ACI about the China air plane which caught fire after landing and AFTER engine shut down.
(No spoilers.)
But it has raised this query from me:
What is the function of a washer?
Apart from the possible exclusion of a spring washer which is used to keep nuts tight.......
I don't get it. As a kid, I accept that I knew "jack" about how that kind of thing worked. There were simply "nuts and bolts".
It seems weird that a washer is needed for the function mentioned in that episode.
Actually if I remember I will put my idea on a better solution at the end.
Also, the word BOLT is somewhat vague and general, as really what most people call a BOLT is not a bolt, but something else which I now can't remember.
But AFAIK, the idea is that two things are to be joined at a point, a "nut and bolt" combination facilitates that.
Similar to nailing two pieces of wood together. I won't start on SCREWS.
As there are "now" nylock nuts and crown nuts, I am really stumped to the mechanics of a washer - as in THAT episode.
But, I am interested to learn and expand my knowledge on their functions if anyone is willing to share.
Thanks in advance.

So the "problem" was the nuts were coming off the bolts. The solution was to put locktight on them.
Why not use a crown nut and lock wire?
Yeah, ok, they would still need to remove the existing one, blah blah. AND the bolt too.... Ok.
But also the "practice" of not having a good view of the area seems silly. It is leaving a whole new vector for faults - as shown - to happen.
That seems very strange.
