| Subject: | Bi-ennial transponder/encoder/static certifications |
In reading 91.411 and 91.413, it says the manufacturer of the airplane can perform
the tests.
Since I built my 6A, I'm thinking that I cando the tests myself and make the logbook
entry.
Testing the transponder codes might be the difficult part - but I have already
built the test equipment and tested the Pitot-static system and verified the altitude
goung to the transponder is correct.
Thoughts please,
Ralph

A common misconception. Yes you built your aircraft. That does not make
you a "manufacturer" in the terms of these regulations.
You need the transponder certified by someone with a repair station
license. There is no certification of the pitot system, only the static
system. The only reason the pitot is connected to the test is to protect
your airspeed indicator from an excessive pressure difference with the
static port.
You can leak test your static system if you ever need to open it between
the required certifications, and that is legal, but the certification
must be done by an appropriately rated repair station.

Thanks - I figured there would be some weasel-wording in there.
Since I have already done most of the tests, I have a high confidence level in
taking it to a 'certified' shop.
Good scoop!
