* The manual doesn't specify where exactly to place the roughly 30 3/32 rivets. If you haven't left the rivets open during the tailcone build and tailcone attachment, one option is to drill out existing rivets, another is to make new holes in between existing rivets, slightly out of line but still keeping 3/16 stiffener edge distance. The minimum distance between rivets in a double row is 4 x diameter (3/8 for 3/32 rivets), see AC 43.13-1B, page 4-20. As the regular rivets are more than 1 inch apart, it isn't a problem to add another rivet at mid distance.<br>[[File:2023-05-12 19-28-17.jpg|400x400px]]<br>[[File:2023-05-13 15-38-37.jpg|400x400px]] | * The manual doesn't specify where exactly to place the roughly 30 3/32 rivets.
