Brief Description: Comm and Xponder Antenna Installation - continued
With help from Ken, completed riveting the doubler plates for both comm antennas and the transponder antenna.
• First, test fitted each antenna to make sure nothing has changed and the antennas attach with no clearance issues. • Clecoed the doubler plates to the interior belly skin, ensure plate orientation is correct. • Countersunk the rivet holes in the outside skin for each doubler plate to install AN426 rivets. • Using rivet tape, secured the NA426 flush rivets through the skin into the doubler plate. • Bucked the rivets to secure the doubler plates, repeated for the second comm antenna and the transponder antenna doubler plate - 30 rivets total, 12 per comm antenna, 6 for the transponder. There is no way any of these antennas are coming off unless the landing gear departs first.
