What does IRAC stand for in the context of aircraft publications?

In the context of aircraft publications, IRAC stands for Interim Rapid Action Change. This term is used to refer to updates or changes that need to be implemented quickly to address safety, performance, or operational issues that have been identified after the release of a publication. The purpose of an IRAC is to ensure that the necessary amendments are made swiftly to maintain the aircraft's airworthiness and operational efficiency.

By designating changes as "rapid," it emphasizes the urgency and enhanced priority for implementing these adjustments compared to standard revisions. This process allows maintenance crews and operators to remain compliant with the latest safety guidelines and operational procedures without waiting for the more comprehensive and slower publication updates. Such an approach facilitates real-time improvements and enhances the overall safety management of the aircraft.
