The Aircraft Discrepancy Book (ADB) is designed to provide maintenance and crew personnel with what type of records?

• A. Accurate, comprehensive, chronological records awaiting maintenance
• B. Real-time flight schedules
• C. Inventory turnover reports
• D. Safety incident summaries

Answer: (A)

The Aircraft Discrepancy Book is a log that captures every issue found on the aircraft and tracks it until it’s resolved. It provides maintenance and crew personnel with accurate, comprehensive, and chronological records of items that are awaiting maintenance, so everyone can see what’s been found, when, and what action is needed. The clear, time-ordered record helps ensure proper follow-up, accountability, and traceability, so the aircraft can be returned to service safely. It isn’t used for real-time flight schedules, inventory turnover reports, or safety incident summaries, which are managed by other records.
