    7) No Data-2 Aircraft Communications Addressing and Reporting (ACARS) traffic was observed after 1707 on 07 March 2014.

  2. Source: Safety Investigation Report MH370/01/2018 2.4.4 Aircraft Systems Analysis (page 377)

    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.
