MAINTENANCE FORMS, RECORDS, AND REPORTS
0001
Department of the Army forms and procedures used for equipment maintenance will be those prescribed by (as
applicable) DA PAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual; DA PAM 738-
751, Functional Users Manual for the Army Maintenance Management Systems - Aviation (TAMMS-A); or AR 700-
138, Army Logistics Readiness and Sustainability.
REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR)
0001
If your D7R Dozer 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. If you
have Internet access, the easiest and fastest way to report problems or suggestions is to go to http://
www.nslcptsmh.csd.disa.mil/webpqdr.htm. The Internet form lets you submit a Product Quality "Deficiency Report
(PQDR).
You may also submit your information using an SF 368, Product Quality Deficiency Report. You can send your
SF 368 via e-mail, regular mail, or facsimile directly to the U.S. Army TACOM Life Cycle Management Command.
The postal mail address is U.S. Army TACOM Life Cycle Management Command, ATTN: RDTA-EN, MS 268,
6501 E. 11 Mile Road, Warren, MI 48397-5000. The e-mail address is
usarmy.detroit.rdecom.mbx.tardec-product-qual-deficienc@mail.mil.
CORROSION PREVENTION AND CONTROL (CPC)
0001
1. 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
items.
2. Corrosion specifically occurs with metals. It is an electrochemical 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.
3. Plastics, composites, and rubbers can also degrade. Degradation is caused by thermal (heat), oxidation
(oxygen), solvation (solvents), or photolytic (light, typically UV) processes. The most common exposures are
excessive heat or light. Damage from these processes will appear as cracking, softening, swelling, and/or
breaking.
4. SF Form 368, Product Quality Deficiency Report should be submitted to the address specified in DA PAM
750-8, TAMMS Users Manual.
