It might be easier to say what a production error is not. If it's a production choice, it's not an error. For example, the use of cardboard Daleks in the early stories is not a production error, because the producers chose to use cardboard to increase the number of Daleks shown. If a cardboard Dalek fell over, that would be a production error.

Also, if something disagrees with the real world, that is not a production error, per T:NO RW.

If I think of anything else, I'll add it to the list.
