How to Fill Out a DA Form 2404?

First, identify the organization working on a piece of equipment in Box 1. Boxes 2 through 6 are used for providing identifying details of the equipment that is being worked on. Make sure you don’t forget to provide the nomenclature and model of the chosen piece of equipment.

Add operation information applicable to the chosen equipment: miles, hours, hot starts and other measuring criteria.

Box 7 is used for listing all technical manuals that are being used. When using more than two manuals, provide identifying information on an additional copy of the form and attach it to your worksheet.

The service member responsible for maintaining or inspecting the equipment must certify the document with their signature and add a correct date in Boxes 8 and 9 together with a maintenance supervisor. The amount of service time required has to be listed in Box 10.

The rest of the space given on the form is used for listing and identifying the inspected items in the maintenance records. Every item number and status has to be identified individually in Columns A and B. Any equipment problems have to be listed in Column C, Deficiencies and Shortcomings. The necessary correcting actions for improving the item have to be listed in Column D. Column E is used for signing off every piece of equipment with the initials of the maintenance personnel.

After the form is fully filled, the records are to be kept with the equipment in case of a need for further reference in other maintenance operations. The maintenance group should also save a copy of the DA 2404 form to maintain an active record of all completed inspections performed on the equipment.
