A. Prepare a Corrosion-Resistent Steel Doubler
(1) If the specific repair data does not give a doubler thickness, the doubler thickness is as follows:
(a) For a skin thickness up to 3 mm (0.1181 in.), the doubler thickness is 1.5 mm (0.0591 in.).
(2) For a skin thickness over 3 mm (0.1181 in.), the doubler thickness is half of the skin thickness.
(a) Cut the doubler from corrosion-resistant steel sheet to the necessary dimensions.
(b) Make a chamfer on the edges of the doubler.
(c) If necessary, shape and form the doubler to match the contours of the composite structure.
(a) Clean the doubler with Non Aqueous Cleaner-- Petroleum Based - (Material No.08BBB1) and a Textile-Lint free Cotton - (Material No.14SBA1) .

(b) Make a chamfer on the edges of the doubler.
(c) If necessary, shape and form the doubler to match the contours of the composite structure.
NOTE: The gap between the doubler and the composite structure must not exceed 0.3 mm (0.0118 in.).
