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.
