Summary
8) Item 8 - Flap Support Fairing Tail Cone
Item No. 8 was found on 24 May 2016 on Gris Gris Beach, Mauritius. The item was brought back to Malaysia for identification and further examination by the Team.
Initial assessment indicated that this could be a flap support fairing tail cone of a B777. The part was identified from the legible numbers that were observed on the inner surface. The following part number 113W9154-401 and serial number 407 were visible on one side. The profile of the part resembled the wing flap support fairing tail cone. The part number was cross referenced to the Boeing component maintenance manual and drawings. This identified it as a component of the wing flap fairing assembly and the fit closely matched that of the No. 1 flap support fairing. As the records of where these fairing tail cones are fitted are not normally kept by airlines, the serial number 407 could not be tracked to any particular aircraft.
Based on the legible numbers and the fit, it is confirmed that it is the tail cone of the No. 1 flap support fairing of B777 and highly likely to be from MH370 (aircraft registered as 9M-MRO).
