L04-01 Tri-Gear Main Landing Gear Mount.
I removed the machine screws from the Mounts and aft spar tunnel. I removed the clecos from the mount also. I then clecoed the aft spar tunnel into the fuselage. I also clecoed the main gear mounts to the fuselage and the aft spar tunnel.
I located and drilled the 1/4in hole through the lower fuselage for the aft arm of each gear mount. I inserted a AN4-16A bolt in each hole to hold it in place. I place a nut on each bolt and only tightened it only finger tight just to keep the bolt from falling out.
