Default Tost release failure

That's a very good point about hooking up the Tost (belly hook) without
pulling the cable. The line crews where I fly now do not know that you can
do that so the hookup always includes: "Open", "Close", "Check". Since I
know the rope was attached in that fashion, I decline the check. If I'm
hooking up myself before getting strapped in (no line crew) then I'll check.

Hank, I also usually tow out behind a golf cart, and that hookup/release
serves as my release check. On my own ship, with a nose tost, I am
comfortable that the hookup process (with rattle check) is sufficient. I
will defer to more experienced pilots when it comes to checking
CG/back-release hooks. I also tell the line that the check has already been
done.

Oddly, my two release failures in over 2000 hrs have both been Schweizers: A
PTT in a 2-32 when the release arm didn't seat all the way due to some mud
on it and resulted in a surprise PTT at barely 200' - I was in the RCP
giving a ride and didn't check the altimeter - but the result was a rapid
180 and return to the launch point for a second (successful) flight; the
other was a jammed release when a tost ring was used on a Schweizer hook
(2-33) - a practice since discontinued, fortunately - and the little ring
somehow jammed the release during the tow. Solved by getting some slack in
the line, but the first time I tried to release the knob didn't move at all!
On both those occasions a release check was performed and passed. So
perhaps my point of view is a bit jaundiced ;^)
