Thanks a lot.

I think there's a reasonable way to explain.
According to the rule of making tag questions, NOT must be used in the contraction form "N ' T". However, there's no such a contraction form for 'AM NOT', and that's the reason for us to use "AREN'T I" instead.
But it's my personal idea to contribute only.
