Murphy's Law: If anything can go wrong, it will.
Corollary: At the most inopportune time.
Probably the best example of how Murphy's Law works is aircraft vacuum
pumps. These evil devices are guaranteed to fail, and they will fail at an
almost impossible to anticipate moment. Why install one at all when there
are much more reliable electric alternatives, especially when at least one
of these alternatives is actually less expensive than the cost of a vacuum
pump (not counting the cost of numerous replacements) and the associated
vacuum operated steam gauges? Hint: http://www.dynondevelopment.com/

Subject: Europa-List: Additional mechanical drive for the vacuum pump 3.6
ALT_MED Misspelled medication name
I have a Rotax 914 UL3 with a hydraulic governor which I need for my
hydraulic constant speed propeller and now I need an additional drive for
the vacuum pump. Theoretically there could be the possibility to use the
belt drive for the second alternator, but the cowling of my Europa XS is too
small for it. Have one of you any experiences, ideas or a solution to do it,
maybe with a cardan drive or a second shaft?
Thank you!!
