I took my plane to the avionics shop where they declared the autopilot DOA, removed it and shipped it to Megit for repairs (I should get it back next week). They also found the electric trim auto pilot disconnect switch defective. They ordered one from Cirrus and will install it when the autopilot comes back. They said that the GPS 1 not sending glide slope information to the Sandel during preflight checks is normal and that the manual is wrong saying that it should.
I then taxied to the Cirrus service center to have some other repairs done (it has been almost 3 weeks since I was there last). When I turned on the master switches I did see the red vacuum light, the yellow aux vacuum light, or hear the aux vacuum. I had a new repair to aid to the list of items for the service center. It seems that the vacuum sensor on the engine driven fuel pump failed. This means that if the engine driven vacuum pump fails not only will you not get a vacuum light, but you will not be able start the backup vacuum pump. The entire manifold has to be replaced. I asked him to wire out the sensor so I would be able to use the backup unit if the primary failed. He said he couldn’t do that since it was against maintenance practices. He put everything back the way it was and the sensor started working (until it fails again). It seems there should some way to manually turn on the backup pump, since a redundant vacuum system is useless if the single point of failure sensor fails.
The CHT works a better now after they installed it on the #2 cylinder where the maintenance manual says it should be instead of on #3 where the factory had it.
We also noticed that the cowling was poorly finished because you could see and feel the fiberglass hatch pattern where they did not use enough resin during construction. I won’t complain about this. They have a full time job just repairing critical components and don’t have time for quality of finish.
