HTA MH370 White Pearl — Boeing 777 Vertical Stabilizer Section

The HTA MH370 White Pearl Vertical Stabilizer Section is a structurally complete major tail surface component comprising a multi-rib-bay section of the Boeing 777 vertical stabilizer from the root attach fitting zone through to the mid-span area, fabricated entirely in carbon fiber reinforced polymer composite primary structure per Boeing 777 empennage specification, providing aerospace engineering institutions, aviation museums, and composite structure research organizations with the most significant CFRP primary structure component available in HTA’s history of sourcing decommissioned 777 structural assemblies from certified aerospace salvage operations across the global airline industry. The vertical stabilizer structure of the Boeing 777 represents one of the largest primary flight structure applications of carbon fiber composite in commercial aviation at the time of the aircraft’s introduction, and the spars, ribs, and skin panels in this section demonstrate Boeing’s specific approach to multi-spar composite box beam design including the rib-to-spar joint methodology, the skin panel splicing philosophy, and the fastener pattern density used in this highly loaded surface. The exterior CFRP skin surface in both the natural bare composite areas and the Malaysia Airlines livery painted areas provides an authentic reference for composite skin surface inspection training, showing the natural mold parting lines, ply boundary locations visible at cut edges, and surface texture characteristics that distinguish aerospace-grade CFRP from industrial composite applications. All attach fitting zones are intact and clearly demonstrate the metal-to-composite joint design philosophy used at the stabilizer-to-fuselage interface. HTA’s advanced composite NDT inspection using ultrasonic C-scan technology is documented in the included inspection report.
