Hi everyone,

I am building Sonex 1517 that had matched hole parts. I am now trying to install the pitch trim rear spring attachment eyebolt re-enforcement per page 6 of the pitch trim instruction sheet.

The re-enforcement plate depicted in the instruction sheet is 2" by 1 1/2". In my Sonex with the matched hole parts there is no physical way this part can be installed as depicted.

There is less than 1" at the top, and I am now puzzled as to what to do to re enforce the eyebolt. (Date on the online sheet is Rev C 3/1/2013)

I can possibly get a 2" by 3/4" piece of .025" material in there. Just not sure if this is enough re-enforcement. I did email tech support.

Has anyone else had an issue with this?

I have been puzzling over the same thing for the last couple of days.
My kit was not match drilled. I built my fuselage per the plans but now at this stage it appears to be rather impossible to install the reinforcement per the trim instructions.
I thought about putting a length on 1/8" X 1" X 1" angle over the top of the fuselage cross tie.
I am interested in what Sonex Tech support suggests.

Since the bungee is not used with the AeroTrim, I removed the hook for the bungee and put it behind the rear spar carrythrough with a doubler to re enforce it on the front.

Relatively easy.

Looks great Robbie! That's one heck of a picture!
