1. Positioned the two upper gear-leg fairings and taped them in place.
2. Located and drilled two access holes through each fairing and the fuselage underneath. The forward ones go through the bottom skin and into the cavity under the floor at that location. The aft ones go through the gear leg attachment access plates.
3. Opened up the forward holes with a step-drill, the used a micro file to file small notches for the keyed rivnuts.
4. Installed a #8 keyed rivnut at each of these locations. (I have now learned that, although I have two rivnut tools and both of them work, both of them are terrible and I need to get a new one.)
5. Removed the access plates, drilled out the holes to #8, and installed nutplates.
6. Sanded, cleaned, and primed the inside surfaces of the access plates.
