The substitute solvent is approved for cleaning metal and alloy parts only. If cleaning involves
any substrate, part or component made of nonmetal such as plastic, composite or elastomer,
specific approval for cleaning using the solvent is required from AMCOM.
6. Deviation from Documentation
This authority to deviate from aircraft system technical maintenance documents is to be used
only where the aviation documentation calls out the use of P-D-680 Type II. No deviation for
other cleaning processes and chemicals are authorized without explicit approval from
AMCOM. AMCOM may approve additional substitutes for P-D-680 Type II as they are
qualified. At that time changes to the documentation will be published in the appropriate TM's
and DMWR's. This message applies to Army aviation documentation substitutions only. All
other equipment or material substitutions must be approved by the respective material
7. AMCOM Environmental Technology Team Hotline
AMCOM continues to reduce the army's dependency on hazardous materials (hazmat) as a
business practice. Maintenance documentation is being revised upon substitute approval by the
responsible organizations within AMCOM. Until documentation is revised, the AMCOM
Environmental Technology Team (ETT) hotline is available to assist in the selection/approval
of substitutes for specific P-D-680 applications. The ETT hotline is also a source for
application specific approval for use of other products as replacements to hazardous materials.
Your organization may request hazmat assistance from the ETT hotline.
