What do the last two digits in the work package manual numbering system indicate?

In the work package manual numbering system, the last two digits are specifically designated to indicate changes or revisions that are made to fit between existing work packages (WPs). This system allows for the tracking of updates in a structured manner. When revisions are necessary, they can be marked with a distinct set of digits that reflect their sequence and relevance to the preceding documents, ensuring that users can easily identify the most current procedural information relevant to their tasks.

This practice is essential for maintaining an organized and systematic approach to managing technical documentation, as it facilitates easy referencing and understanding of the progression of changes made over time. The use of the last two digits to signify revisions helps maintain clarity and consistency within the manual numbering, allowing aviation structural mechanics to quickly locate and reference the appropriate work instructions or updates needed for maintenance and structural tasks.
