As Airborne backs away from the vacuum pump business, Champion says its new design may end premature failures. For a typical instrument pilot even a current instrument pilot loss of critical gyros due to vacuum pump failure is hardly trivial. Of less consequence but no less annoying are pumps that suddenly give up the ghost without warning in VFR, creating yet another maintenance headache for the owner.
Pumps can and do fail frequently and almost always unpredictably.
