Hi
Lynn, There is a Coupe on this airfield which has the back-up rings installed
but no holes whatsoever. They too were covered in 1994, neither has the engine
turned over, it just sits there neglected. I cannot say there is corrosion,
however it certainly is a candidate. My Coupe actually had the Swiss Cheeze AD
done correctly, it is one of the few things that were done correctly on this
Coupe, and I have been pulling all the wing panels every year. This seems to
only make sense, if there is a panel which can be removed, I remove it and take
a look regardless of requirements to meet the annual inspection. I believe this
may be one of the reasons some of the Coupers are having a hard time figuring
out what this latest AD is about, most of us have probably been doing it for
years. If the Swiss Cheeze AD was done correctly, there is no need to put in
more inspection panels. I can only speak to my Coupe which was built in 47, I
don't know the regs regarding wing panel holes on other models, as I did not
keep a copy of the AD's for any type other than my
own.Pete

Bill; The AD 2003-21-01, which becomes effective December 1, 2003, requires inspection of the outer wing panels within the next 6 months and then repetitively thereafter at intervals not to exceed 12 calendar months.
The AD requires the installation of the inspection openings in the outer wing panels (which was required by AD 94-18-14R1) and repetitive inspections in accordance with Univair Service Bulletin No. 28 Revision C. dated July 8, 1999.
This repetitive inspection should have already been accomplished on your aircraft, unless it has not been flown since 1995.
My previous comments on this AD were concerning the fact that we did not have any notice that it was published in the National Register for comment. I think the problem was originated by those Coupers with fabric wings that had the inspection openings back-up rings installed, but never cut the openings out for repetitive inspections. I have a set of those wings in my paint shop now that had that done in 1994 and had never been cut out for any inspection. Additionally, there were a lot of Coupes that were in storage, and those have slowly come out of retirement and corrosion has been found.
