You can
bet that, before my next flight in my LAK-17a, I'll be giving those parts a
very close look.

Always a good idea, especially on a LAK-17a! I won't mention any
names, but a well known fellow around here had his 17a rudder cable
disengage (factory installed incorrect swedge fitting... oops!),
leaving him rudderless a few years ago. Thank goodness there are no
springs in that design, as he was fairly low so was committed to
landing. Titanium testicles and a cool head combined with skill and
luck for a successful outcome.

Glad the JS1 pilot is OK; I hope he buys his rigger a sixpack and
writes this up someday. I also hope this doesn't screw Jonkers...
