Brittain servo fix

[Mooneymite]

The original Brittain PC (back before PC meant "politically correct") was installed as a no-nonsense, basic autopilot.  Years later, it's still going.  When it does stop working, the fix is usually simple and cheap and Cecilia at Britain is very generous with her support.

My PC had begun needing more and more right wing down correction, so I figured there was a leak.....usually due to a leak around the rubber boot.  I re-taped the boot, but it didn't correct the problem.  Finally, I removed the entire servo (you don't have to have monkey arms, but it helps if you do) and discovered the servo was leaking but from the center, not the boot.

I asked Cecilia she advised:  "The sealant used is commonly known as “Perm-e-Tex” but its proper name is “aviation form-a-gasket”.  You can generally find it at one or more of the national retail auto part stores."

Now that is a cheap fix!  Try fixing your King, or S-tec autopilot with Permatex.

Just got mine going after discovering a torn boot. Gotta love a system we can basically fix with bubblegum and popsicle sticks (slight exaggeration but only barely).

I take it Brittain is still answering their phone call?   It's a shame that a company that designed such simple, reliable and safe system is no longer in business.

There's one in each wing at the inspection panel of the inboard edge of the ailerons. And two more behind the radio access panel on the side that go back to the rudder.
