AE-2014-054 - Technical assistance to the Department of Civil Aviation Malaysia in support of missing Malaysia Airlines flight MH370 on 7 March 2014 UTC
Malaysia, as the country of registration, has investigative responsibility for the accident. In accordance with Annex 13 to the Convention on International Civil Aviation Aircraft Accident and Incident Investigation, the ATSB appointed an accredited representative and a number of advisers (ATSB investigators) to the Malaysian investigation. As part of Australia’s role in leading the search and recovery operation in the southern Indian Ocean, the ATSB opened an external investigation, AE-2014-054: Technical assistance to the Department of Civil Aviation Malaysia in support of missing Malaysia Airlines flight MH370 on 7 March 2014 UTC.
So far, the investigation has produced the following ATSB reports:
CSIRO: The search for MH370 and ocean surface drift
This report explores the possibility that an improved ability to simulate the path taken by the flaperon across the Indian Ocean might yield an improved estimate of the location of the remains of the aircraft on the sea floor. CSIRO: Ocean surface drift report
First Principles Review
This report documents the proceedings and outcomes of the First Principles Review meeting on the search for missing Malaysia Airlines flight MH370 held in Canberra from 2 to 4 November 2016. Participants consisted of experts in data processing, satellite communications, accident investigation, aircraft performance, flight operations, sonar data, acoustic data and oceanography. The purpose of the meeting was to reassess and validate existing evidence and to identify any new analysis that may assist in identifying the location of the missing aircraft.

MH370 Search and debris examination update – 2 November 2016
The MH370 Search and debris examination update (under the Search and Debris tab) provides an update to the MH370 search area definition described in previous ATSB reports. It comprises further analysis of satellite data, additional end of flight simulations, a summary of the analysis of the right outboard wing flap, and preliminary results from the enhanced debris drift modelling.
The DSTG analysis of Inmarsat data has been published in the paper, The Use of Burst Frequency Offsets in the Search for MH370.
Debris examination reports 1, 2, 3, 4 and 5
Debris examination reports including the identification of items recovered from beaches in South Africa, Mauritius and the Tanzanian coast. Debris reports 1, 2, 3, 4 and 5.
MH370 – Definition of Underwater Search Areas (Published: 3 December 2015)
The MH370 Search Strategy Working Group has conducted ongoing analysis of data to glean any information that might assist in locating the aircraft. To this end, the ATSB engaged the Defence Science and Technology Group (DSTG) to provide expert analysis of available data relating to MH370. The analysis used models of the Inmarsat satellite communications data, aircraft dynamics and meteorological data to determine likely flight paths which were in turn subject to validation experiments to ensure they aligned with actual flight data.
The DSTG analysis has been published in the book, Bayesian Methods in the Search for MH370
This analysis has informed the ATSB’s latest report, MH370 – Definition of Underwater Search Area Update [Download PDF] (update 10 December 2015)
An updated version of the ATSB report was released on 10 December 2015 to clarify that the ‘power loss’ mentioned on page 9 occurring between 17:07:48 and 18:03:41 was referring to the Satellite Data Unit (SDU) only. The SDU did not respond to an automatic interrogation from the Ground Earth System (GES) at 18:03:41 UTC, although it resumed working at 18:25:27.
MH370 – Definition of Underwater Search Areas (Published: 26 June 2014 (updated: 18 August 2014)
The location of the search areas was guided by continuing and innovative analysis by a Joint Investigation Team of the flight and satellite-communications data. This analysis was supplemented by other information provided to ATSB during this period. This included possible underwater locator beacon and hydrophone acoustic detections. An updated version of the report was released on 18 August to clarify a number of technical aspects.

MH370 – Flight Path Analysis Update
Refinements to the analysis of the flight and satellite-communications data gave greater certainty about when the aircraft turned south into the Indian Ocean. This analysis was published to supplement the previously released report MH370 – Definition of Underwater Search Areas.
