Completed step 1 page 18-06. Clecoed the A-1202B outboard flaperon skin and A-1202A-L inboard flaperon skin to A-1205 main ribs. Worked the skins by clamping trailing edge between two ¾ aluminum angles 8 ft long. Used clamps to adjust the bend at the trailing edge until the skins essentially laid flat on the ribs. Completed the skin preparations and priming then clecoed the skins to flaperon frame structure.
