Two layers of diagonal planking have now been completed on the bottom surface of the wing of G-ACSP “Black Magic”. The two layers are a mirror image of each other to give a final even surface. Each plank was thinned to the correct thickness as per DH plans, then glued and nailed to the spars and stringers. The next phase is to complete the surface and install the undercarriage then the wing will be turned over for the top surface to be started and the retract mechanism installed.
