Capen" Subject: Avionics-List: 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 ________________________________ Message 2 _____________________________________ Time: 07:27:07 AM PST US From: Kelly McMullen Subject: Re: Avionics-List: Bi-ennial transponder/encoder/static certifications 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.

Since I have already done most of the tests, I have a high confidence level in taking it to a 'certified' shop.
