We just noticed some play on our club L-23. It was detected in the stick while on tow with a forward CG. Does anyone have experience with a horizontal stab being loose on an L-23? The elevator auto-hookups have large pins, but it seems like there's no way to really tighten anything...

You should probably take any looseness in the elevator drive or horizontal stabilizer attachment quite seriously.

Can you describe the play more precisely? Is the play in the elevator actuation, or in the horizontal stab attachment?

Word from Blanik America is the MM provides the tolerance for how much movement is acceptable, so we're going to measure that tonight. The play is in the stab attachment. Apparently there are a few sources that can cause this.
