Winch Launch - Fatal

Wench launching can be very dangerous, especially if she's heavy and
your aim is poor...

Please read the accident report and its conclusions.

The accident described in the report was not so much of an issue
when Earlier ASW,17, 18,19,20 were designed and built. Same applied
to SH.
The accident is directly related to more powerful winches. The same
situation would develop with less powerful winches but it took much
much longer. There was more of a ground run to recognise the wing
on the ground and the acceleration was much less which meant that
when it went wrong it went wrong much slower with more time to
react. Not so with a modern powerful winch, when the problem occurs
it goes wrong very quickly, probably too quickly for any chance for a
meaningful reaction. What is described has always happened from time
to time, the only difference is that it did not start killing people until

the winches got powerful.

Damn autocorrect meant wrench launching.

Now autocorrect has you throwing tools about!

I just launched a wrench the other day trying to get the *&#$@ retaining bolt out of the rudder of a Grob Twin Astir. Actually pretty cathartic.

Not to make light of this tragic situation, but a little humor hopefully won't hurt...

Sew, ewe did not really mean two say "wench", then?

The wench launch comment was meant for another newsgroup!

How dangerous is winch launching went compared to aero-tow? In the States most launches are aero-tow.

Those that know me, also know you would never see me launch a wrench, as experience has taught me never pick up a tool.
