When updating a technical order, what must be done?

The correct approach when updating a technical order is to ensure that all information is reviewed for relevance. This process is critical because it maintains the integrity and accuracy of the technical order, ensuring that all users are working with the most current and applicable information.

Reviewing all information helps to identify any outdated content or unnecessary details that could lead to confusion or errors in operation. It also ensures that any new procedures, technologies, or safety protocols are incorporated into the technical order, enhancing both clarity and functionality for the aircrew.

While considerations like urgency in deleting items or the order of changes may be part of revision processes in other contexts, those are not the primary focus when updating a technical order, where a comprehensive review for relevance takes precedence.
