How long has it been missing for?
If 523R and 526H comes out, 536D,538Z should go in. 527E 528C
comes out, 540R and 550L should be in. (For AMDEP)
533L 534J 535G out, 541M 542K 544E should go in for
refurbishment.
530U and 531S are they seen on 854 and 969 recently?
Please note, This is just only my assumption, not the real
deal.
TIB541M was spotted on 858 last Friday. Not sure whether it is
spotted this week.
