I think it's pretty obvious our pump went belly up on us yesterday. Our vacuum powered instruments went out.
We noticed a tapping/slapping noise once we got on the ground, which lead me to believe something had come off. I pulled the cowl today to see if the lines had come off the pump, as the plane just came out of annual. Looks like everything is intact.
Is there typically any noise associated with a dying/dead vac pump?
Is the plane flyable sans the instruments if the pump is dead? Will running it dead hurt anything else, is a better question.
We are about to go with an EFIS and this may have been the perfect sign that it is time. LOL.
Just wondering if we can run the engine without killing anything, with a failed pump.
