Replace the existing steel tube diagonal members, counting forward from the tail post as follows, using Civil Aeronautics Manual 18 repair procedures or manufacturer's recommendation.
(a) Right side only, third member: Replace with 12 MMS. (15/32"), outside diameter, 1MM. (.040") wall thickness tubes.
(b) Right and left side, fourth and sixth members: Replace with 14 MMS. (9/16") outside diameter, 1 MM. (.040") wall thickness tubes.
