= George,

Please check the specifications for the new hose material you got = from Spruce.

I believe you will find the limitations on installed bend radius c= ould be a problem - especially in the nose wheel well installation.<= /P>

 

Be safe,

Sub= ject: [LML] Hydraulic hoses

As I have previously posted, the outer, = protective rubber coating on most of my hydraulic hoses, after 16 years and= 1350 flight hours, have begun to dry, crack and flake off.  The rubbe= r covering is at most 3/64th inches thick and clearly, to me, is on the hos= e to provide protection from chafing or debris thrown up from tires during = ground operations.

I have replaced the deteriorated rubber covering = on the hoses in the main wheel wells with a product I purchased through Air= craft Spruce, called "Rescue Tape."  It is wonderful stuff and is much= more sturdy than the original rubber.  I also used that tape on a cou= ple hoses under the seats.

I decided to replace a few hoses just to = get back in the business of building again and the attached picture is an e= xample of one hose I produced.  I am not going to send my hoses off to= Sacramento Sky Ranch for re-make, as a couple responders so sternly sugges= ted.  I'm a homebuilder thank you very much, and I will make my own ho= ses.  I bought the hose and couplings from A/C Spruce.

There is= nothing to suggest to me that my airplane is not airworthy, as Brent Ragan= would suggest.  If that were true it should have been un-airworthy at= the first sign of a deteriorated hose covering, which I began noticing som= e months ago.  I believe this to be an ongoing maintenance requirement= and should be addressed as such.  

I assume there will be the = usual comments on the hydraulic hose situation, which I and other Lancair f= lyers will welcome.
