Standard Cirrus C-Hook

I purchased a Standard Cirrus with a bent C-Hook. This was bent when
the previous owner was putting the fuselage in the trailer. I ordered
a
new C-Hook from M&H Soaring and they sent me the new gray C-Hook
and as you can see, it is a different size.
Should I try to find another small one like the original or find a way
to install
the new one?

Any suggestions?

any good machine shop should be able to replicate a new hook from the
dimensions of the old one

Hi Randy
you will not get the new hook to fit as it not only has a bearing on the
inside of the hook, it also has a bearing that runs around the outside of
the hook and ensures the hook is captive.
Given that this is the elevator drive, I would not be bodging it up, the
new hook will not fit and modifying the tailplane to accept the new hook is
a lot of work and probably not feasible anyway.
I would be talking to the Schemmp Hirth agent in your area and getting the
correct part for the job.
It is possible to bend the hook when rigging the tailplane due to incorrect
rigging technique and forcing the tailplane on to the fitting.

Good Morning JJ,
I do not know how to post a picture on RAS. That is why I
added it on a mac web page.
I have scanned in a drawing from the Cirrus manual
that show the dimensions.

http://web.me.com/rgteel/Site/Cirrus_C-Hook.html



Or you can send a picture directly to me. My email
in on the webpage.



Randy



You can always compare yours to the one that I have posted
on this page.

May I recommend that you make sure that you continue to comply with the
1970 Tech Note 278-2 for the Std Cirrus both for the hook and the bearing.
See:

The elevator connection for the Std Cirrus is idiosyncratic to rig, not
difficult to mis-connect (in my hands), and requires careful checking
before flight. Not a place for second hand or non-standard parts.

John,
Thanks for the link for the ADs and Technical Notes.
It is a great site.

This glider has been complied with for the the 1970 Tech Note 278-2.
The C-Hook is the same one shown in this Tech Note.

I have not been able to anything that mentions using this larger
hook and bearing.

Any chance the larger is for a Cirrus77?
