What does ADB stand for in aircraft maintenance?

In aircraft maintenance, ADB stands for Aircraft Discrepancy Book. This is a crucial document used by maintenance personnel to record any discrepancies or issues identified during inspections or routine checks of the aircraft. By documenting these discrepancies, maintenance crews can ensure that issues are tracked, prioritized, and addressed effectively, enhancing the overall safety and reliability of the aircraft.

The Aircraft Discrepancy Book serves as a vital communication tool among maintenance teams and helps maintain an accurate history of the aircraft's operational status. This enables thorough inspection and repair processes, ensuring that all necessary actions are taken before the aircraft is cleared for flight.

In contrast, the other options do not accurately reflect a standard term associated with aircraft maintenance. Understanding the importance of the ADB and its role in the maintenance cycle is essential for ensuring that discrepancies are managed appropriately, contributing to overall aviation safety.
