1968.01.18 - Contamination of Apollo CM 103's potable water


A meeting was held at MSC to determine necessary action concerning recent contamination of CM 103's potable water, oxygen, and water-glycol lines.

North American Rockwell proposed that all 103 aluminum lines in the potable water and oxygen systems (approximately 72 segments) be replaced; and proposed to follow a chemical flushing procedure for the water-glycol lines to remove the aluminum oxide and copper contamination. North American estimated that these actions would cause a 15-17 day serial impact. Removal and replacement of all lines would result in an estimated impact of 45 days. A decision was made to concur with the North American recommendation and on January 19 Kenneth S. Kleinknecht, MSC, informed Dale D. Myers, North American, of the concurrence and authorized him to proceed immediately. In addition, Kleinknecht appointed a Special Task Team for Spacecraft 103 Contamination Control to ensure timely review of all contractor activities associated with removal of the contamination from the spacecraft environmental control system coolant system. Members of the team were: Wilbur H. Gray, Chairman; A. M. Worden, W. R. Downs, Jack Cohen, A. W. Joslyn, R. E. Smylie, R. P. Burt, and W. H. Taylor.

On February 20 Myers notified Kleinknecht of initiation of the potable water line changes and setting up of a monitor water-glycol system that would duplicate CSM 103 operations during the balance of checkout and would be examined for corrosion damage just before Flight Readiness Review.
