Default Stuck Installing HS-01231C

Hi Everyone,
I am at the step on the Horizontal Stabilator where I finished cleco'ing the skins to the skeleton and before riveting, I am supposed to cleco and then final drill the HS-01231C's. If you look at the attached picture, I have cleco'ed it in one corner and I have pointed out where the other three holes on the long edge aren't lining up. I tried turning it, checked all four and same problem. Has anyone else seen this?

The rule of thumb for the RV-12 is that if it doesn't fit, the builder did something wrong.

Thank you Jim. I am putting them on exactly as you have them but only one of the holes at align to the forward spar lines up. The other three don't, no matter which one I try its the same alignment issue.

If you look at the two pictures in the above posts, note that the inboard longitudinal rivet pattern is parallel to the edge of the gusset in the OP's pix and the reverse orientation in the #2 pix. Something is amiss here! Flip the gusset over? My plans are out in the hangar so I can't verify the correct orientation.

It looks to me like the two photos show the opposite install. Maybe flip the peice over? Never heard of an RV12 hole miss match but there is always a chance?

Have you looked at the pictures and instructions in the applicable SB? It appears your gusset plate is installed in the wrong orientation.

ps -- My comments are based on my construction of an RV-12. I think that the RV-12iS stab is the same.

I agree in my picture, my gusset is upside down, the problem is that when I flip it over I have the same exact problem. I can align the six vertical holes and one of the top horizontal holes but the other three horizontal holes do not align.
