I deburred, cleaned and primed the 4 antenna reinforcing plates in preparation for installation later in the day. I located the AN426AD3-4 rivets and set the tools up. I planned on back riveting the plates to the fuselage skin. With the plates dry, I clecoed them in place. My EAA tech advisor Steve Barnes arrived to help with the riveting. First with back riveted the OP-47 AHRS bracket to the bottom fuselage skin. I had mostly installed this months earlier, but had to wait for help riveting the bottom rivets. Next we back riveted the 2 VHF antenna plates and the transponder and ADSB antenna plates. I ran the rivet gun and Steve held the bucking bar.
