All programmed communications via ACARS prior to 1707:29 UTC were working satisfactorily.
After this last automatic ACARS transmission over the SATCOM, either the ACARS was turned off or the AIMS had a fault that prevented ACARS transmissions while certain other functions such as inertial data forwarding did not appear to be significantly affected.
