It is important that any corrosion prob- lems with the howitzer 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 SF 368, Product Quality Deficiency Report. Use of keywords such as “corrosion,” “rust,” “deterioration,” or “cracking” will ensure that the information is identified as a CPC problem. The form should be submitted to: Commander U.S. Army Armament Research, Development and Engineering Center ATTN: AMSTA–AR–QAW–A (R)/Customer Feedback Center Rock Island, IL 61299–7300 1–11 NUCLEAR HARDNESS Not applicable. 1–12 SECURITY MEASURES FOR ELECTRONIC DATA Not applicable.
