The Australian Transport Safety Bureau (ATSB) concluded that two items of debris found on the Mozambique coast were almost certainly from Malaysian Airlines Flight 370, the Boeing 777 aircraft, registered 9M-MRO that went missing on March 8, 2014.
On 27 December 2015 and 27 February 2016, two items of debris were independently found, approximately 220km apart, on the Mozambique coast. Both items were investigated by the ATSB to determine the origin.
The first part was initially identified from a number stencilled on the part (676EB), as a segment from a Boeing 777 flap track fairing (Fairing No. 7) from the right wing. All measurable dimensions, materials, construction and other identifiable features conformed to the applicable Boeing drawings for the identified fairing.
The 676EB stencil font and colour was not original from manufacture, but instead conformed to that developed and used by MAB during painting operations. The part had been repainted, which was consistent with MAB maintenance records for 9M-MRO.
The second part was primarily identified from images showing the materials, construction and “NO STEP” stencil, as a segment of a Boeing 777 RH horizontal stabilizer panel. All measurable dimensions, materials, construction and other identifiable features conformed to the Boeing drawings for the stabiliser panel.
The part was marked on the upper surface in black paint with “NO STEP”. The font and location of the stencil were not original from manufacture, however the stencilling was consistent with that developed and used by Malaysian Airlines.
A single fastener was retained in the part. The fastener head markings identified it as being correct for use on the stabiliser panel assembly. The markings also identified the fastener manufacturer. That manufacturer’s fasteners were not used in current production, but did match the fasteners used in assembly of the aircraft next in the production line (405) to 9M-MRO (404).
Ongoing work is being conducted with respect to the marine ecology identification as well as testing of material samples. The results from these tests will be provided to the Malaysian investigation team once complete.
