What is one type of TCTO that requires immediate action?

Urgent Action TCTOs are classified as requiring immediate attention due to their potential to affect safety, operational capability, or the overall integrity of the aircraft. When an Urgent Action TCTO is issued, it indicates that there is an immediate need to address a significant risk or problem that cannot wait for the routine maintenance schedule.

This type of TCTO mandates that specific corrections or inspections be performed without delay to mitigate the risks involved. It highlights a sense of urgency and the necessity for swift compliance to avoid accidents or further technical issues.

In contrast, other types like Routine Action TCTOs typically allow for scheduled compliance, Record TCTOs are generally for documentation purposes and do not require action, and Interim TCTOs may involve temporary measures that also do not carry the same immediate urgency.
