Is this normal or indicative of incorrect rigging? Control yoke/aileron motion left and right is the the same. Aileron cable tension is correct and the aircraft flies normally. Thanks, Mike ________________________________ Message 2 _____________________________________ Time: 09:02:54 AM PST US Subject: Re: TeamGrumman-List: What a drag . . . From: Gary L Vogt Bob, I would like a trace of the wing rib. I will reverse engineer as much as I c an and see if I can find a profile that is close. We may never know what its exact behavior is, but we can get close. At least we can get an idea where max L/D is.

To my eye it l ooks like the wing cannot possibly be lifting any longer, but apparently tha t big camber on top is still cranking pretty good. By this time however, we have a pretty blunt leading edge that kills a lot of bugs (and I think two h ummingbirds on the way to Pennsylvania!) > > I can trace you a copy of the rib on paper and send it to you to hang on y our wall next to your TV if you like.

From: "Doug Doty" <39marinette@gmail.com> I wanted to start a different thread as I realized this was hijacking the flying with a level thread that is so interesting in itself. Sorry !!! Any way I got the tail cone off this evening and looked for looseness, none found ?? I worked the two sides against one another and simply cannot find any movement. It seems to me that it has always been this way or has twisted over time. The plane has about 1990 hours on the airframe and no known previous damage history. I will post a picture below that demonstrates the right side up as the left is leveled with the HS. Any additional thoughts from anyone on this. I measured the differential with a digital level on each elevator inboard and outboard with with a slight up preload on each and the right is .8 degrees off from the left. -------- 1977 AA5B N28454, Fuel Totalizer, Lopresti Nose, Red Rudder Cap, 4 cyl. egt, stock otherwise.
