Is service bulletin #20 saying that if your aircraft serial number is 147 or higher, and if there is no movement detected per service bulletin #15, that torque tube replacement is not required before continuing with "the section for all aircraft"?
Carbon Cub SS #153
What a bunch of baloney SB 20 is. We buy a new $200,000 airplane and we are splicing wires to do the repair...amazing!
Why wasn't a new stick sent out, it is too short any way. The Torque Tube issue was bad enough and now this. The resaon for the 10 day manditory is not clear either. Have there been failures? We want to be totally safe of course but why not at annual? An explaination would be a good thing. I am obviously very unhappy with the way this has been handled. Anyone else?

I was surprised when the SB arrived (timing was fortuitous, as my airplane had just gone in for its annual), but CC has been forthcoming with information and Vera was most helpful in making sure parts arrived on time.
As was mentioned in the original post in this thread, there is more information in this thread in the Sport Cub forum.
