I am building a very slow QB RV-8 (2010 QB wings and fuselage). After having to replace the lower right longeron and weldment (due to a drilling error during gear alignment), I was researching the rivet lengths etc for reassembly, when I noticed something. DWG 67 shows four bolts going through the lower engine mounts and the lower longerons. I didn’t recall removing bolts when I removed the right lower longeron, so I did a sanity check and had a look at the left side.
Both sides were fitted with AN470AD4 rivets instead of the AN3 bolts! I contacted the mothership, and they confirmed I should have bolts there, and that they had not heard about this issue before.
Short story long, I just wanted to get this out there as a potential issue on other RV-8 QB fuselages, please have a look. You may get a small amount of vomit in your mouth when you see the deriveting involved to correct this issue!
