Now that you say it, I have a feeling that there is a chance
that the Batch 3 OACs will also get extended, since their
deregistration dates are around the same time as the CACs...
No, the Batch 3 OAC will never get any second lifespan
extensions...From three separate tender notices, a total of 289
O405s will be de-registered between July 2013 and June 2015; after
offsetting the value, there will be only 19 O405s de-registering
from July 2015 onwards.
Aside from the 6 OAC O405s (TIB827P - TIB832Z) that will be
de-registered between December 2015 and September 2016, the
remaining 13 O405s are from the CAC batch which will all be
de-registered in July 2015.
