Spruce and plywood ribs were connected with gusset joints. Some heavy-duty ribs contained pieces of ash and walnut, as well as the special five ply that included veneers laid up at 45°. The upper skin construction was in two layers of 0.25-in five-ply birch, separated by Douglas fir stringers running in the span-wise direction.Aviation, 1944 p. 12. The wings were covered with madapollam fabric and doped in a similar manner to the fuselage. The wing was installed into the roots by means of four large attachment points.Batchelor, John and Malcolm Low. de Havilland Mosquito Manual (Plane Essentials). Victoria, Australia: Publishing Solutions, 2008. .Batchelor and Lowe 2008, p. 7. The engine radiators were fitted in the inner wing, just outboard of the fuselage on either side. These gave less drag. The radiators themselves were split into three sections: an oil cooler section outboard, the middle section forming the coolant radiator and the inboard section serving the cabin heater.Jackson 2003, p. 87.
