An SD-42-BSLF rivet, was riveted onto the left wing, A hole was already prepunched. A hole was drilled into the J channel on the top of the wing and a tie-wrap was installed. The 1/8 plastic tubing was routed from the rivet to the root of the wing through the J channel. Although we did trim the drill templates, we noticed the guide hole was already were we needed it, we just need to expand the hole, but for that we need a 15/32" drill bit. A plastic tubing adapater was created from PT-035X1/4 and the inboard end of the 1/8 tubing was inserted into it and sealed with RTV.
