RUH ..ROH...

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...

We found cracks (two, 1in long) in our rudder stop drilled when we
purchased.. reskinned.

Small crack in port aileron found when paint removed... reskinned.

FIVE cracks... something is happening INSIDE the stabilator...

Cherokees are tough birds...this should NOT be happening...

I would not fly this aircraft..

Where are the cracks located Ross?

I do not think ANY cracks are permitted on the control surface areas,
depending on the year of manufacture.

I am absolutey positive about this on rhe rudder and ailerons...they
need new skins.

Stabilator? not sure..

You might ask on the Cherokee chat group..someone there WILL know..
ALL known about Cherokees is in that group!

Jay and other owners of this aircraft. Any documentation on cracks
forming on the horizontal tail surfaces. The -235 I am helping on annual
had three additional cracks in the skin beyound the two that were
repaired by the previous owner. Got some old skin and made conforming
patches.



They are on the horizontal stabilator. All go across the raised portion
that Piper blends into the skin (skin stiffiners ?). The patches were
made out of the same skin material so it would fit nicely. All are on
the starbord (right) side of the aircraft and more inboard. 4 were on
the top. Two previously patched years ago. And a new one on the bottom
(at least it was not stopped drilled like the two on the top not
patched. Engine mounts look to be fine.
