Reading ahead, I was confused with the installation of the angle at the top and forward end of the fuselage/tailcone.
First look at Page 10-03, Step 7. F-1283C has a flat end and a beveled end. Now look at Page 10-10, Figure 2 and Detail A-A. I cannot tell if the flat end goes forward and the beveled end goes aft. Detail A-A suggests the flat end goes forward. Figure 2 is not clear.
Would seem to make more sense with the beveled end forward because this would then match the J channel at the forward end of the Upper Left and Right Skins (they are beveled at the forward end). But this does not seem to agree with Detail A-A.
Will send Van's an e-mail.
UPDATE: Per an e-mail from Ken Scott at Vans, he tells me that the beveled edge goes aft and the flat edge goes forward. I will install it that way, and, as such the installation will be in agreement with Detail A-A.
