I owned an ASW-20A for 25 years. Now have a 27. I was very careful in checking the hookups (like JJ). You will want to add to your list to check the tail bolt - yes, I flew all afternoon in mountain turbulence with the tail bolt in my pocket!! That 3M white tape holds very well!

I also know of a modification that can be done to the top of the tail so that the elevator push rod will still push the elevator up, even if the hookup is not connected. Not sure this would help unless the CG was 60%+. I never did this mod and decided it was best to double check the hookups.
