What does the acronym IRAC stand for?

The acronym IRAC stands for "Interim Rapid Action Change." This term is commonly used in the context of aviation maintenance and structural integrity, referring to temporary modifications or updates made to equipment, procedures, or documentation that need to be implemented quickly to address safety or performance issues.

Interim Rapid Action Changes are typically necessary when an immediate response is required due to identified deficiencies or safety concerns, allowing for swift and effective action to ensure continued operational safety and compliance. The focus is on rapid implementation, which distinguishes it from more extensive or permanent changes that might require a longer approval process.
