The fourth and fifth digit of a TCTO number represents what?

Explanation:
In a TCTO number, digits are arranged to carry tracking information for the modification. The fourth and fifth positions are the sequential Technical Order number, meaning they increment each time another TCTO is issued against the same base TO. This keeps each modification distinct and shows the order in which they were published, so maintenance teams apply them correctly. The date, page numbers, or any code word are not represented by those digits.
