Why is an action request (AR) not considered a replacement for a TODCR?

An action request (AR) is not considered a replacement for a Technical Order Data Change Request (TODCR) primarily because ARs have a more limited scope. While both ARs and TODCRs serve the purpose of addressing changes or requests related to technical orders and procedures, ARs are generally used to request specific actions or minor modifications that do not significantly alter the technical order's intent or function. In contrast, a TODCR is designed for more substantial changes that may affect the overall safety, performance, or compliance of the equipment and its operations.

Consequently, because ARs are focused on a narrower area of concern and typically do not encompass broader implications, they do not fulfill the more comprehensive and formal requirements associated with submitting a TODCR. This distinction ensures that significant changes are properly reviewed and documented through the more rigorous TODCR process, maintaining the integrity and reliability of technical orders critical to aircraft systems operations.
