My mind is totally BLANK

But.... For which MEL categories can the repair interval be extended?

I know the original limits:
A: - Whatever is on the comments
B: 3 days
C: 10 days
D: 120 days (?)

I'm also pretty sure D is non-extendible.

I put B & C on the idea that A wouldn't be extendible either based on custom length.

Yep B and C for a maximum of 4 times.
