| Subject: | Elevator - Elev Trim Tab Skin (E-619) and Elev Counterbalance |
Skin (E-713)
Greetings:
Ref: RV-8A (RV-7 is the same = Drawing 4)
Looked on Matronics, but found no answers to these questions
Question 1:
When building the Elev Trim Tab Skin it says: 1) bend the Skin with the wooden
brake, 2) bend the 2 metal "tabs" that are at each end, 3) match drill the Trim
Tab Horns (E-717 and E-718) to the Skin. So far no problem, BUT now how do
you then dimple the Skin where the E-718 (INBOARD Trim Tab Horn) goes as the 2
rivets for it are approx 1/8" from the bent Skin Tab ????? One of the 2 rivets
is also near the bent trailing edge which makes it impossible to get at.
Question 2:
Instructions say to "bevel the inboard and aft edges of the Counterbalance Skin
(E-713) locally where the Counterbalance Skin overlaps the (Elev) Spar and Rib
flanges to provide a smooth transition between the Counterbalance Skin and the
Elevator Skin." This does not make sense. I can see "beveling" the Elev Skin
"at the point" where the Counterbalance Skin goes UNDER the Elev Skin to make
a smooth transition. Am I missing something ???
Appreciate your help,
