But, and it's a big "but", it only takes one at the wrong time to bite in the worst way. I've never had one fail but someone I knew took off IFR (from the Santa Barbara airport, where the departure was out over the ocean) and entered the clag at about 500 ft. His vacuum pump must have failed soon thereafter because he augered into the Pacific ocean less than 2 minutes after takeoff. Only takes one and the first one may be the bad one. Dan Schaefer
