(9) Section of R/H aft fuselage structure. (Target 256: see App C Volume 2 pp –.)

The structure fractured at body stations 1640 and 1960 and at strangers 4R and 17R. Extensive heat damage occurred to frames and stringers between body stations 1760 and 1880 and between stringers 4R and 11R. Smoke deposits and heat discolouration of the paint were evident on the skin surfaces behind some frames and stringers which had become detached from the skin. Eight 9G barrier net straps burned off at their fuselage attachment fittings. Blistering and discolouration of the paint occurred on the outer skin surface between body stations 1800 and 1840 and stringers 4R and 11R. Deformation and buckling of the skin were also evident in this area. This structure matches with targets 197 and 263:
