What are the three types of MAFs found in the ADB?

The three types of Maintenance Action Forms (MAFs) found in the Aircraft Discrepancy Book (ADB) are classified as Up MAF, Down MAF, and Partially Mission Capable MAF.

Up MAFs indicate that the aircraft is ready for flight and can perform its intended mission. This denotes that any discrepancies have been resolved, and the aircraft is fully functional.

Down MAFs signify that the aircraft is not mission-capable due to maintenance issues or discrepancies that need to be addressed before it can return to service.

Partially Mission Capable MAFs represent a middle ground where the aircraft can perform some missions but has certain limitations or outstanding discrepancies that must be noted.

Understanding these classifications is crucial for maintenance and operational readiness, as they help maintain clear communication about the aircraft's condition and what actions need to be taken to ensure mission capability. This structure supports efficient tracking and prioritization of maintenance actions, ultimately contributing to the overall effectiveness of aircraft operations.
