Happy holidays to all
My question for CH701 builders is
My elevator has been assembled with part 7h2-6 the front horizontial stabilizer
bracket of .040 thick material,not the now recomended .063. This fix appeared in the
July/Aug 06 news letter. To replace the bracket I would have to drill out all the rivets in the top skin.
Is it necessary to replace the bracket? Will inspections alone allow for safety?
Who has done the fix and who has not
do not archive

John,
I still have my 701 with the .040, started flying a year ago and have 95 hrs so far. I plan on just keeping an eye on it, so far it looks good as new. If it were me and I was still building the plane, I would probably replace them with the heavier ones before I finished the plane and painted it. I can tell you that once you start flying the motivation to go back and change things drops considerably.

I finished my Horiz Stab as you did. I finally took of the top skin and replaced those brackets with .063 material. I had to beat myself up first but it feels better now its done....Geoff

Just where were those cracks - can you see them without disassembly??

Hi JG,
Here is a photo of right forward mount. They were very visable. So checking for cracks is now a part of every pre-flight.
