3. Notes .........................................................................................................Edit

1. KL ACC was responsible for the provision of alerting service for MH370.

   Safety Investigation Report MH370/01/2018 1.18.1 Provision of Air Traffic Services and Areas of Responsibilities

   The Team noted that MH370 was operating in the airspace delegated to KL ACC and the last air-ground radio contact was with KL ACC. MH370 did not contact Ho Chi Minh ACC and Ho Chi Minh ACC was unable to establish radio communication with MH370.
   Hence KL ACC shall be responsible for the provision of alerting service for MH370.

   7) Activation of KL Aeronautical Rescue Coordination Centre

   KL ARCC was activated at 2130 UTC [0530 MYT]. The DETRESFA message was disseminated via the AFTN at 2232 UTC [0632 MYT], 01 hour and 02 minutes later. No activity was recorded in the RCC Logbook between 2130 UTC [0530 MYT] and 2232 UTC [0632 MYT].

3. Inclusion of extracts from both Table 1.18E and Table 2.2C may appear to be duplication. However, the tables contain different events, and where the events are the same, the wording may be slightly different. Both versions are included for consistency.
4. The context of Table 1.18E is the Factual Information in the Safety Investigation Report MH370/01/2018 and the context of Table 2.2C is the Analysis section.
