SAFETY INVESTIGATION REPORT MH370 (9M-MRO)
2.2.1 Review of Flight MH370 before its Disappearance
- The MH370 from Kuala Lumpur to Beijing was a normal daily scheduled flight. It took off at 1642 UTC [0042 MYT].
- There was no indication of any unusual operations prior to departure and during the flight until the last secondary radar position symbol was recorded by ATC at 1721 UTC [0121 MYT] as detailed in Table 2.2A -Chronological of events before disappearance of MH370 below.
- Preparation of the flight was in order from the time the Filed Flight Plan29 (FPL) message was filed and transmitted 12 hours before the flight.
- The flight crew reported on time for duty and there was no delay in the departure of the flight (Figure 2.2C [below] - Departure message).
- There was also no report of any significant or unusual health-related issues for the flight and cabin crew.
- The radiotelephony speech segments from the cockpit with KL ACC were determined from the voice analysis of the ATC radiotelephony communications recording to be that of the FO before take-off and the PIC after take-off.
- The transfer of control was effected three minutes before the estimate for IGARI. There was no recording of transmission (voice or in written form) of KL ACC informing HCM ACC (via direct land line) when MH370 was transferred 3 minutes earlier than the estimate for the Transfer of Control Point (TCP).
Note:
Based on reconstruction (Section 2.1) of the flight profile conducted on the B777 simulator, the flight would be at waypoint IGARI one minute earlier than the original estimate of 1722 UTC [0122 MYT].
