Has Not Yet Determined If The Pieces Are From MH370, Or Even A Boeing 777

Two items of fibreglass-honeycomb composite debris were recovered near Sainte Luce on the south-east coast of Madagascar, having reportedly washed ashore in February 2016. They were hand-delivered to the Australian Transport Safety Bureau on September 12, 2016, and were initially reported in the media as being burnt.

The ATSB reports that no manufacturing identifiers, such as a part numbers or serial numbers were present on either item, that may have provided direct clues as to their origin. At the time the report was issued, the items had not been identified and work in this respect is ongoing.

A dark grey coloration was present on a significant proportion of both sides of each item. Detailed examination of these areas showed that the colour related exclusively to a translucent resin that had been applied to those surfaces.

A cross section through the panel showed a clear delineation between the dark resin and the other surface coatings without any evidence of gradual transition. The lighter grey surface areas resulted from a thinner film of the same resin applied over an off-white background. This confirmed that the dark color of the coating was an inherent property of the resin, and not the result of exposure to heat or fire.

Despite no evidence of overall gross heat damage, two small (<10mm) marks on one side of the larger item and one on the reverse side were identified as damage resulting from localized heating. A burnt odour emanating from the large item was isolated to these discrete areas. The origin and age of these marks was not apparent. However, it was considered that burning odours would generally dissipate after an extended period of environmental exposure, including salt water immersion, as expected for items originating from 9M-MRO.

Work is ongoing to determine the origin of the items, specifically, whether they originated from a Boeing 777 aircraft.

The dark grey colouration on the outer surfaces of the items related to an applied resin and was not the result of exposure to heat or fire. Three small marks on the larger item were indicative of localized heating. The age and origin of these marks was not apparent.
