Completed this SB this weekend. I DID NOT remove the stabilator since I am in annual inspection concurrently and already had the bulkhead cover removed. Instead I opted to remove the two bolts that secure the counterweight balance arm at the stabilator then shimmy into the tail section, twist and pull the counterweight/arm loose, perform service bulletin then shimmy in again to reinstall the counterweight.

Of course I had assistance of someone at the spar to insert the bolts while I was still in tail and able to twist arm as needed to align the bolt holes. Much easier, in my opinion, than complete removal of the stabilator.

I did not say I wasn't stiff and sore today....

60 years on 6'2" and 205# doesn't make the shimmy easy, but I didn't want to do all the work involved in removing and replacing the stabilator. I admit that at one point laying on my belly, reaching up to twist so my helper could find the bolt hole alignment I was wondering if the EMS would attempt to pull me out feet first and over the fuel tank or just opt to cut the -12 in half just behind the bulkhead.

Has anyone weighed the counter balance weight? I'm curious if it would be easier, while inside, to unbolt the weight first and then remove the arm. Do the work outside then reassemble in the reverse order. After it's reassembled, then drill through the extra hole in the lead weight to balance the stabilator.

Like some others I"m nearing 80 and have a volunteer RV12 builder to help with the inside work. I hope to start sometime during the 2nd week in August.

Not that heavy. Definitely easier to just grab it with the weight still attached.

Made a 3D printed fixture that makes drilling these holes a little bit easier:
