Brief Description:  Riveted forward side skins

Installed the forward side skins. There are many areas where the rivet call-out in the plans are inconsistent as follows:
1, The parts manual Pg 06G-01 clearly shows Avex rivets in the three rear most, spanwise, rivet rows. This is also reflected in the Figures manual Fig 06G-05A "Fwd Fuselage - Belly Skin Rivet Schedule and Figure 06G-05B Fwd Fuselage - Belly Skin Rivet schedule. However Figure 07H-09 (which is mistitled "Tailcone to Centersection Rivet Schedule" (S/B "Fwd Fuselage to
Centersection....)) shows AAPQ 41 and -42 rivets in this joint. (The rivet pattern shown also does not quite match the actual pattern). I believe the AAPQ rivet call-out is the correct one, since this is a major joint that picks-up the centersection belly skin, landing gear/skin doubler, and centersection spars. AAPQ's would also be consistent with the rest of the fuselage joint call-outs, the Avex rivets are generally used only for field fasteners. (I used AAPQ rivets).

2, Similar issue, different fasteners and location - The parts manual Pg
05C-17 item #3 calls-out a AAPQ-43 rivet in the rear spar bulkhead to upper longeron connection. But this rivet appears to be a CCPQ 44 in the Figures Manuel, Figure 05C-06. Since this is the terminating fastener in a major load path I used the higher strength CCPQ rivet.
I contacted Ed at Rans and he confermed that the AAPQ or CCPQ rivets should be used.
