A drain hole must be drilled to prevent water accumulating in the top of the fin. This hole should be drilled through the outer skin (drain to the outside not down through the fin) at the lowest point in the fin rib. The correct position can be easily seen once the tailplane has been removed. The hole should be 4 mm diameter. 3. Colour coding of controls. JAR 22.780 reserves the colour red for use on canopy jettison controls only. Therefore the fuel shut off valve must be painted black and the red sheath removed from the master switch.
