1. Purpose. Provide a cleaning requirement to remove salt / salt laden sand and other corrosive
contaminates from radar set AN/TPN-18A returning from OCONUS Desert Operations.
Environmental conditions within the Southwest Asia (SWA) theater of operations were conducive to the
introduction of salt laden sand and other corrosive substances into the interior surfaces of the radar. These
substances, if allowed to remain will accelerate the corrosion process and lead to premature corrosion
damage. Immediate removal of these substances is imperative in order to minimize future corrosion damage.
This Technical Bulletin (TB) is issued to provide special inspection and cleaning procedures for all
deployed/redeployed radar sets.
2. Priority Classification. NORMAL.
a. Equipment In Use. No later than 30 days after redeployment from Desert operations. Deployed radar
sets will complete cleaning procedures as necessary but as a minimum at next preventative
maintenance checks and services (PMCS).
b. Equipment in Storage. No later than 30 clays after redeployment from Desert operations. Equipment
deployed will complete cleaning procedures as necessary but as a minimum quartly.
3. End Items to be inspected. All radar sets after redeployment from Desert operations. Deployed radar sets
will complete requirements as necessary but at a minimum at next phase.
