Where do you put the MCN/JCN on a daily turnaround MAF?

The correct placement for the MCN/JCN on a daily turnaround MAF is in the discrepancy block of the location that the MAF contains. This is important because the Maintenance Control Number (MCN) or Job Control Number (JCN) is intended to identify specific maintenance actions or discrepancies on the aircraft. By inserting it into the discrepancy block, it aligns with the primary purpose of that section, which is to document issues or required repairs associated with the aircraft.

This practice allows maintainers to easily track and reference the actions taken related to particular maintenance events during that specific turnaround. Maintaining information accurately in designated blocks ensures that records are clear and can be quickly understood by personnel reviewing maintenance logs. Proper documentation is crucial for efficient aircraft operations, safety, and compliance with military regulations.
