In Part 15, I Akzo primed the four pieces that make up the Instrument Panel Frame Assembly. During today’s session, I riveted the four pieces together.....along with a ton of nutplates. The plans excerpt below shows how all four of the parts and all the nutplates get assembled to make Frame. The Frame is riveted together with a combination of AN426AD3-3, 3-3.5, and 3-4 rivets (I chose to go up to a -4 on several of the rivet locations). There are a total of 23 K1000-06 and two K-1000-08 nutplates.
Here is the forward and aft side of the completed Instrument Panel Frame Assembly.
You may have to zoom in on the picture to see all the nutplates.....they are everywhere!
