1. I decided to disassemble and perfect the installation of the flap actuator arm. First, I removed the upper attach angle and removed all the hardware. Then I cut the safety wire and removed the cupped washers I'd previously installed around the rod end. I replaced these with flat washers, then reassembled everything using new hardware, lubricated the rod end, and re-safetied it in accordance with the applicable Vans Service Bulletin. Then I installed the flap actuator cover using new #6 screws with nylon washers to prevent scratching the cover. 2. Clecoed the top skin in place and clamped it tight to the fuselage using a band clamp. Began drilling and clecoing the skin edges to the fuselage.
