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 the future.
While corrosion is typically associated with rusting of metals, it can also include deterioration of other materials such as
rubber and plastic. Unusual cracking, softening, swelling, or breaking of these materials may be a corrosion problem.
If a corrosion problem is identified, it can be reported using Standard Form 368 (Quality Deficiency Report). Use of key words
such as “corrosion,”“rust,”“deterioration” or “cracking” will assure that the information is identified as a CPC problem.
The preferred method for submitting QDRs is through the Army Electronic Product Support (AEPS) website, under the
Electronic Deficiency Reporting System (EDRS). The web address is h
