1. Purpose. Provide a cleaning requirement to remove salt / salt laden sand and other corrosive
contaminates from Landing Control Central AN/TSQ-71B and AN/TSQ-71B (modified) 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 Landing Control Central. 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 Landing Control Central facilities.
