Vacuum Pumps and other stuff ( Long)

Guest Discussion

I was told today that dry vacuum pumps should never be rotated backwards. The vanes just don’t seem to like going that way. I would be interested in knowing if those of you who have experienced multiple failures have the FBO do a lot of towing and manueuvering of your planes. If the prop is in the way of the tow bar do they move the prop forward or backward to make room? Has anyone else been told to always move the prop forward for this reason? I have also been told that wet pumps are much more reliable but can cause a mess. (He didn’t elaborate on that one)

I would hope that during this lull in SR20 deliveries that Cirrus will go back to the drawing board and start a process of product improvement based on the trailblazing done by those who have been “delivered”. Sounds almost religious. Someone at Cirrus should be locked in a closet and when the newest SR20 rolls off the

line in a few months the following will have happened:

1. The landing light will be under the cowl like the 22. ( I'll pay for the upgrade)

2. The altitude anoroid ( or whatever the hell is causing hard start or rough running ) will be fixed. If not we all march on TCM Headquarters.

3. The HSI problems are fixed.

4. The transponder problems are fixed.

5. The weight problems will be
   fixed due to new ideas in construction
   brought about by an incentive program for
   employee ideas.

Everyone from Walt forward to the latest happy owner has actually been a producton test pilot and the lessons learned need to be acted upon. This lull in deliveries could actually be a godsend if the oportunity is taken for a review of these matters. I eagerly await my Dec delivery.

Not a problem for us.

  1. The HSI problems are fixed.

Century problem with shipping but now that we have a good one we love it!

  1. The transponder problems are fixed.

Have not had the problem with 157cd

We will wait and see on this one.

No I believe anyone who has owned a 172r has been a test pilot, I feel the 20 has what we call growing pains…ED

Agree, should have been there from #1.

  1. The altitude anoroid ( or whatever the hell is causing hard start or rough running ) will be fixed. If not we all march on TCM Headquarters.

Problem has been analyzed, solution found. Fix on the way. Yes, it ook some fiddling to get the engine going in the colder lattitudes, but the workaraounds worked.

  1. The HSI problems are fixed.

Agree. Youy pay a high premium price for everything in avaiation, so we can rightfully insist on high quality. Century problem.

  1. The transponder problems are fixed.

Have not seen it in N144CD (220+ hours)

  1. The weight problems will be

Agree, though I don’t label it as a problem, merely an unsolved opportunity

Wouldn’t have missed the 220+ SR20 hours for the world. All is relative and we get spoiled…
