Service Letter 00068

And my friend used a sharp screwdriver and hammer to easily pop one of his off. He used slow-curing JB Weld.

That's good to know. But we've been using glue, or in some cases epoxy, for years. Nothing new there. SL-00068 promises to be an upgrade to make servicing the stab less frustrating.

I did use JB to hold the washers last time but I think the shims installed per the SL is a better solution, especially used in combination with a stab service cart.

Contributing to the frustration though is the problem of handling the bulky stabilator off and then back on the airplane while fitting the mounting bolts. We have 3 RV12's here, possibly a fourth, and one building so I made up a stab service cart to make all this upcoming work much less frustrating.

I borrowed the idea from someone else and anyone is free to copy.

I used the same cart with blankets to do the SB on mine. I figured that since this was the first time removing the stab in 1100 hrs that if the next time was 2200 hrs it wasn't worth making a special fixture.
