What Packy described is a servo tab, not an anti-servo
tab. A servo tab coming loose will definitely cause loss
of control. An anti-servo tab coming loose isn't *necessarily*
as catastrophic but I wouldn't push it just the same. Free-floating
surfaces that *can* backdrive the control surface aren't a good thing.

Dave 'aeroservoelastic' Hyde is correct. It's a servo tab on my plane
not an anti-servo like Bobs. Thanks for the correction. For some
reason it didn't occur to me that the Archer has the same system that
is on the Warrior. Is that right? So then Bob's system and my system
are markedly different. I last instructed in the Warrior in 83'.
You'd think I could remember these things. If the trim jackscrew
cleans off all the threads kinda like on alaska airlines, you may
still have some elevator authority on the archer, that's true. But
how stable is it going to be as you slow down for approach and put out
flaps? Is it going to slam back and forth against the trim limit
positions? Will the trim limit stops hold? The Alaska guys kept
dicking with it trying to simulate the trim needed for an approach
when it let go. After that accident most of us resolved to not try
and free up a jammed stab as procedure dictates. Just head for a
lakebed and land flaps up. On the point about the second control
tube that comes off the counter balance side, on my airplane this
turns into a cable run. But for sure, if my servo tab bolt fell out,
my airplane would just turn into a pointed tool box. So you mothers
stay away from it, understand?

Interesting conversation Bob.
