Piper 235 tail skin

Ross, something is very wrong here...

Here is the entry, sec 4-55 of my (PA28-151) manual...

IN BOLD ITALICS....

WARNING!

The use of patch plates for repairs of all moveable tail surfaces is
prohibited The use if any filler material normally used for the repair
of minor dents and/or materials used for filling the inside of
surfaces is also prohibited on all moveable tail surfaces.

I understand "stop drilling " is also prohibited...


That is the same exact thing that's in my service manual, which is
also the Cherokee Warrior PA-28-151 & -161 edition (part # 761 539),
and doesn't seem to cover the -235 models specifically.

I did find these interesting threads over on the piperowners.org
forum, which seems to suggest that the older straight-wing Cherokee
service manual did not have the prohibition against patching control
surfaces.

It might be the difference between an old manual and a current one. I have
an ancient copy of the PA28 service manual and it doesn't prohibit control
surface skin repairs. When a crack jumped the stop-drill hole on my rudder,
my IA declined to repair it (had to reskin). We compared service manuals and
my old one didn't have the prohibition, but his current one did. Word on a
Piper forum was that the prohibition was added to the PA28 manuals by Piper
in the 90s (which would explain why my old skin was stop drilled).

That is my understanding as well. Additionally, you must use the latest
service manual, so repairs done now have to conform to the current
service manual, as I understand it. I don't believe you need to go back
and change old repairs if they were correct for the service manual
revision that was current when the repair was done.

I can find no such prohibition in my service manual (P/N 753-586, Feb 27, 2004). It contains
information (skin thickness, checking balance, etc) on how to do it.

That's strange. When my IA showed me his current manual (on CD), it had
the prohibition. As I recall, it was worded the same as described in Dave's
post above.

Might want to check that P/N on the manual. Yours is a hershey-bar -180, right? I was starting
to think that only the taper-wings had the prohibition in there.

Good point. My old manual covered all of the PA28 variants. I wasn't
aware that they now had separate manuals for the tapered wing models.

Thanks,
