\n\u2018The Problem Resolution Team (PRT) recommends change out of the valve using Atlantis to cannibalize the part. This will be going to the Noon board for approval.
\n
\n\u2018If the OK is given to R&R (Remove and Replace) the valve, access is needed behind the WMC panel and the anticipated duration is eight hours to perform the R&R.
\n
\n\u2018After the R&R, time has to be found in the schedule to perform two cabin leak checks with the vehicle powered down.\u2019<\/p>\n<\/font><\/p>\n
