Rear Left Elevator Spar Screwup.. January 1st, 2007
I went ahead and dimpled both sides of the front spar (used to attach the trim tab). It turns out the top half needs to be countersunk so the piano hinge can later be match drilled. I would just dimple the piano hinge too (have done it before on a training project with no problems), but match drilling it to the already-dimpled holes of the skin and spar is going to be a major pain.
It’s not very expensive, so I just ordered another one from Van’s. I had a couple more things I needed anyway, so it’ll be (somewhat) worth the handling and shipping fee….
