Suspect:
TIB920C TIB1010Y
(AMDEP SP
AMDEP/GYDEP 969)
TIB811J
(AMDEP/GYDEP 969
AMDEP/GYDEP 961)
920C and 1010Y could be the fleet addition for 969-4 and 969-5
though, Which means 478M and 479K brothers gets to sleep as SP.
811J should lie behind of 527E if I am not wrong. 969-10 is 811J
and 527E is 969-11.
