Use. DA Form 2404 will be used by personnel performing inspections, maintenance services, diagnostic checks,
technical evaluations, marine condition surveys on watercraft, and PMCS (unless otherwise noted):
To inspect all components or subsystems that make up one equipment system, you may use one DA
Form 2404 or separate forms for each subsystem.
To inspect several like items of equipment; e.g., one DA Form 2404 to inspect 25 M16A1 rifles.
As a temporary record of required and completed maintenance.
To list faults that operators or crews cannot fix and list parts replaced.
By unit maintenance during periodic services to list all faults found and action taken to fix faults. When
used to inspect several like items, the DA Form 2404 will list all deficiencies, shortcomings, and
corrective action taken.
General instructions. The way to complete some blocks and columns on DA Form 2404 varies with the form
use. Make sure to read the instructions that apply to the use of the form. When more than one DA Form 2404 is
needed for an inspection or service, print the page number on the right side of the form's title block. (Put 1 of 2
on the first page and 2 of 2 on the second, etc.) Parts on order or actions pending under Anticipated Not-
Mission-Capable (ANMC) conditions may go on the DA Form 2408-1-4 with a diagonal status symbol.
Administrative motor pools, using ADP cards or other automated forms, do not need the DA Form 2404.
Disposition. The DA Form 2404 will be kept in the equipment record folder or in a protected cover until it is
completed if no faults have been found. If faults are found during an operator's or crew's PMCS, it will be given
to the maintenance supervisor for action. Maintenance section leaders will review the DA Form 2404 prior to
destruction to ensure all corrective actions have been completed. Transfer faults that must be fixed at support
maintenance to the DA Form 2407 and attach DA Form 2404. Faults that cannot be fixed until a part comes in
or action(s) that must be deferred will be entered on the DA Form 2408-1-4.
PMCS Verification. It is the responsibility of all personnel to keep the DA Forms 2404 up to date and accurate.
In order to support the mission, the operability of each piece of equipment must be known at all times. In order
to keep current on the status of identified faults or malfunctions, periodic maintenance services, and
needed/completed repairs, personnel should spot-check DA Forms 2404 frequently.
Verify Operators Are Able To Correct And Report Maintenance Deficiencies.
Maintenance Deficiencies. Based on a preventive maintenance checklist, operators are required to
perform before-, during-, and after-checks to equipment/systems. If maintenance deficiencies are
discovered, operators are expected to notify their supervisors immediately. Some maintenance can be
performed by operators. Tools and supplies needed for maintenance by laboratory personnel must be
requested as needed.
Tools and Supplies. A list of tools and supplies that are required can be found in FMs and supply
catalogs (SC) of the appropriate laboratory. For maintenance by direct support or facility engineers,
tools and general purpose supplies are normally supplied by the support organization. Specialized repair
parts installed by support organizations should be stocked by the laboratory. Examples include
replacement heating elements for water stills, flash-point apparatus, and gum baths. Many repair parts
for laboratory apparatuses are now available by national stock number (NSN) or part number. A listing
of the current NSNs of major items in petroleum laboratories and their component repair parts,
manufacturer codes, and related information are available in Petroleum/Chemical Laboratory Supplies,
Equipment, and Related Technical Assistance Program, STSGPIM. This publication is available from
the U.S. Army General Materiel and Petroleum Activity, New Cumberland Army Depot, New
Cumberland, PA 17070.
Verifying and Reporting Deficiencies. If repairs can be performed at the unit level, DA Form 2404 is
used to identify faults. If the senior technician/sergeant determines that repairs are beyond unit
capabilities, it becomes necessary to request maintenance from supporting units by completing a
Maintenance Request (DA Form 2407). DA Form 2404 accompanies the work order.
