REPORTING EQUIPMENT IMPROVEMENT RECOMMENDATIONS (EIR)
If your M9 ACE needs improvement, let us know. Send us an EIR. You, the user, are the only one who can tell us
what you do not like about your equipment. Let us know why you do not like the design or performance. If you have
Internet access, the easiest and fastest way to report problems or suggestions is to follow the instructions and links
For ALL non-Aviation/Missile Warranty, EIR and PQDRs must be submitted through the Web Product Quality
Deficiency Reporting (PQDR) site. The Web PQDR site is: http://www.nslcptsmh.csd.disa.mil/webpqdr/

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 items. 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. Plastics, composites, and rubber can also degrade. Degradation is caused by
thermal (heat), oxidation (oxygen), salvation (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.
SF Form 368, Product Quality Deficiency Report should be submitted to the address specified in DA PAM 750-8,
The Army Maintenance Management System (TAMMS) Users Manual.
OZONE DEPLETING SUBSTANCES (ODS)
The continued use of Ozone Depleting Substances (ODS) has been prohibited by Executive Order 12856 of
