Which individuals is the Aircraft Discrepancy Book designed to support?

• A. Pilots only
• B. Ground support mechanicals
• C. Maintenance and crew personnel
• D. Managers in marketing

Answer: (C)

The Aircraft Discrepancy Book is a communication and documentation tool that captures faults and tracks the corrective actions needed to restore airworthiness. It’s used by the people who actually encounter, investigate, and fix issues—both the crew who identify discrepancies during operation and the maintenance personnel who diagnose and repair them. That collaboration ensures faults are recorded, assigned, and closed properly, with clear traceability for safety and regulatory compliance. So the best fit is maintenance and crew personnel, since they jointly handle reporting, diagnosing, and rectifying discrepancies. Pilots alone wouldn’t cover the repair process, ground support mechanics are part of the maintenance workflow but don’t encompass the full crew–maintenance collaboration, and marketing managers have no role in airworthiness documentation.
