       Congratulations Mark.

       If you don't mind a bit of critique...
       I notice you have some long runs of stainless braided hose which
   look
       poorly
       supported. This stuff acts like a saw on aluminum with the a bit a
       vibration. Especially where it loops between the cooler and the
   PSRU it
       would appear that it could saw on the Al coolant system parts.

       Have a read up on the firewall forward section of AC 43 -13

       Properly supporting lines hoses and wiring firewall forward is
   something
       Cirrus does very poorly. The SR22 I did an import inspection on
   looked
       like
       it was asking for all sorts of sensor harness problems in a
   couple of
       hundred hours.

       Regards,

       Hi Mark,
       Not a problem, I welcome any constructive criticism. Sometimes
   pictures
       can be deceiving. As in the line going between the oil cooler outlet
       and the psru inlet. It is a -4 and only about 6" long and not even
       close to touching anything else. Originally, it was aluminum
   tubing,
       but I didn't feel comfortable with that, so I changed it to
   braided SS.


       Some of the other lines may need to be tied down better. I'll
   look at
       that again tomorrow. If you look closely you will see that I used
       rubber snubbers wherever two lines crossed. An old airport bum
   showed
       me that trick (using a piece of heater hose and run a tie wrap
   through
       the center and around both lines). It keeps them from rubbing
   and also
       from moving around and touching against anything else. I used
   some ADEL
       clamps in various places to support hoses and keep them from
   touching
       (such as the line going past the alternator, or the long one
   going from
       front to rear over the top of the engine. It has two clamps
   (maybe it
       needs two more?).

       Thanks for mentioning this. I'll look at it again with a more
   critical
       eye.

       Mark S.


   Mark,

   I'm wondering if I missed it so I'll ask, what's the estimated weight of
   the 20B total installation?

   Allen,


Sorry, I don't have the all-up FWF weight for my installation.  I think
Al stated that his was 425#.  I did do a preliminary w&b about six
months ago and the whole a/c weighed 1975#.  The ES normally comes in
closer to 2100#.  Of course, it isn't painted.  So, I figure that it
should come in about 50# lighter than an IO-540 installation, everything
else being equal.

I'll be doing a final W&B pretty soon and will let everyone know the
results.

Mark.
