REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR)
If your BHL needs improvement, let us know. Send us an EIR. You, the user, are the only one who can tell us
what you don't like about your equipment. Let us know why you don't like the design or performance. (E-Mail:
TACOM-TECH-PUBS@conus.army.mil) We will send you a reply. The preferred method for submitting Quality
Deficiency Reports (QDRs) is through the Army Electronic Product Support (AEPS) website under the Electronic
Deficiency Reporting System (EDRS). The web address is: https://aeps.ria.army.mil. If the above method is not
available to you, put it on an SF 368 (Product Quality Deficiency Report), and mail it to us at: Department of the
Army, U.S. Army Tank-automotive and Armaments Command, AMSRD-TAR-E, PDQR MS 268, 6501 E. 11 Mile
Road, Warren, MI 38397-5000.
CORROSION PREVENTION AND CONTROL (CPC)
Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that any
corrosion problems with this item be reported so that the problem can be corrected and improvements can be
made to prevent the problem in future systems. Corrosion specifically occurs with metals. It is an electro-
chemical process that causes the degradation of metals. It is commonly caused by exposure to moisture, acids,
bases, or salts. An example is the rusting of iron. Corrosion damage in metals can be seen, depending on the
metal, as tarnishing, pitting, fogging, surface residue, and/or cracking. Plastics, composites, and rubbers can also
degrade. Degradation is caused by thermal (heat), oxidation (oxygen), solvation (solvents), or photolytic (light,
typically ultraviolet) processes. The most common exposures are excessive heat or light. Damage from these
processes will appear as cracking, softening, swelling, and/or breaking. SF 368, Product Quality Deficiency
Report, should be submitted to the address specified in DA PAM 738-750, Functional Users Manual for the Army
Maintenance Management System (TAMMS).
