Hi All

As part of the my fox’s up coming annual I am replacing the majority of the hardware to include the wing and stabiliser strut rod ends, and (following a recent post regarding a failure) all the flight control rod ends,

However my problem is as follows, the build book I have gives the part Nos as, for example FRE-50, FRE 49 and so on.

None of the parts supplies companies (Aircraft spruce or LAS in the UK) list these part Nos in their inventory, is this a Denney part no, 

Has anyone been down this route before, indeed would the present kitfox company supply hardware kits for older models?

Many thanks

John

John,



I wonder if replacing the rod ends will give you what you are after with 

regard to the failure recently mentioned.  As I understand it, it was the 

stud the rod end was screwed onto that failed.    It is my understanding, 

further, that the threaded studs used by the early Kitofx kits were actually 

allen bolts welded to the ends of the tubes.  There was some discussion in 

the past as to the possibility that the weld process somehow hardened the 

bolt making it subject to work hardening.  There have been failures at the 

horizontal stabilizer in the past as well - the factory went to 1/4" vs. 

3/16" after a couple of failures.

Sure been there. Just go to Aircraft Spruce and 

buy the one that fits. No problem. They are 

standard parts. Don't worry about what the build 

book says. It did not use industry part numbers 

but used inventory numbers They are long gone. 

The stuff you buy will be aircraft quality.

Lowell,

  You are correct I still have the parts I 

dissected. This was a cost cutting idea that was 

never blessed by an engineer. Buying an "AN" part 

will result in a much stronger solution.

Many thanks for the replies guys,

To determine the part no of each rod end would require removal and measuring

Perhaps there s someone who has done this already and still has the part Nos handy?

Many thanks in advance.
