What is the typical reason for issuing a RAC (Rapid Action Change)?

• A. Extend publication shelf life
• B. Address safety of flight or faulty equipment items
• C. Update contact information
• D. Change instrument color

Answer: (B)

Rapid Action Change is issued to quickly address issues that could impact flight safety or involve faulty equipment. When a hazardous condition or a faulty component is identified, a RAC provides immediate instructions to maintenance and flight crews so operations can continue safely without waiting for the next full publication revision. It focuses on urgent, safety-critical fixes, sometimes altering procedures, inspection intervals, or installation specifics until a permanent change is published. The other options aren’t about urgent safety fixes—extending shelf life, updating contact details, or cosmetic changes don’t address immediate flight safety concerns.
