The cockpit voice recorder, the flight data recorder and data from air traffic control all suggest that flight MH17 proceeded as normal until 13:20:03 (UTC), after which it ended abruptly. A full listening of the communications among the crew members in the cockpit recorded on the cockpit voice recorder revealed no signs of any technical faults or an emergency situation. Neither were any warning tones heard in the cockpit that might have pointed to technical problems. The flight data recorder registered no aircraft system warnings, and aircraft engine parameters were consistent with normal operation during the flight. The radio communications with Ukrainian air traffic control confirm that no emergency call was made by the cockpit crew. The final calls by Ukrainian air traffic control made between 13.20:00 and 13.22:02 (UTC) remained unanswered.

Pattern of damage
As yet it has not been possible to conduct a detailed study of the wreckage. However, the available images show that the pieces of wreckage were pierced in numerous places. The pattern of damage to the aircraft fuselage and the cockpit is consistent with that which may be expected from a large number of high-energy objects that penetrated the aircraft from outside. It’s likely that this damage resulted in a loss of structural integrity of the aircraft, leading to an in-flight break up. This also explains the abrupt end to the data registration on the recorders, the simultaneous loss of contact with air traffic control and the aircraft's disappearance from radar.

Further investigation
In its preliminary report, the Safety Board presents the initial findings of an investigation that is still fully underway. More research will be necessary to determine more precisely what caused the crash and how the airplane disintegrated. The Board believes that additional evidence will become available in the period ahead. From this point on, the research team will start working towards producing the definitive investigation report. The Board aims to publish the report within one year of the date of the crash.
