To maintain liquid‐tightness in an integral wing fuel tank at the junction of the stringers 12, 13 and the bulkhead 10 forming the end wall of the tank, each stringer is divided into inner and outer portions 12, 13 respectively, the webs of the two portions being in alignment and bolted to a cylindrical connector 14 passing through a hole in the bulkhead, the stringer webs being disposed in vertical longitudinal slots 25, 29 in the connector which grips the bulkhead between a collar 24 and nut 22. Scaling washers 20, 21 bear against the bulkhead and the vertical flange 18 of an angle‐section member supporting the bulkhead. The stringer dangers are riveted to the wing skin 11 and ribs 16. During assembly the web of the outer stringer section 13 is first inserted in the slot 25 and bolted to the connector 14, and the latter with the ring 21 in pisition is then passed through the hole in the bulkhead and the nut 22 and ring 20 screwed into position, after which the inner stringer section 12 is inserted in the slot 29 and bolted to the connector 14.
