Default Transponder Certification Requirements

I've just completed the build on my RV12is and awaiting my FAA Registration / DAR Airworthiness Inspection.

Question: Do I need to have my TRANSPONDER certified by an avionics shop or am I OK to fly for two years until my first test / certification?

Any input would be appreciated.

Default You need to get it certified

A transponder certification is a system test, it is not just testing a single box.
The antenna, encoder and wiring are all part of the system.

It really matters on the airspace you will be flying in. If a transponder is not required, then you can make your first flight where you are located. However, do NOT operate the transponder in flight until it has been certified by an appropriate technician.

I sometimes run across this as a DAR. IF the transponder signoff is not in the book and the aircraft is located in airspace that requires it, then I do remind them that it needs to be certified prior to the flight. It is not technically an airworthiness item for an airworthiness inspection, but it is an operational requirement, which is the responsibility of the pilot.

I believe the above is correct. My DAR believed the above to be correct. But, just to be sure, he said, Iíll double check with the FSDO. You guessed it, the morons there said it was required before A/W could be issued. It was easier to just get it done (fortunately thereís a shop on-airport) than argue with the government. This was the first, but unfortunately not the last, time the FSDO didnít understand their own rules.

Default Just do it

The certification takes about ten minutes plus another ten for paperwork. The shop charged me $100. Just do it.

I know it's rare these days, but if the altitude data is not supplied by the EFIS (ie: separate altimeter/encoder) then an altitude data correspondence test must also be accomplished on new installations. Technically it has to be done with a glass panel as well but I think everyone knows (even the feds) if the altimeter is also the encoder it's not really necessary but I will still list the SN of the air data unit on the test sheet and sign it off as xpdr test with data correspondence, I do verify correct displayed/xmitted altitude as well to keep it 'legal'. And I do charge more than $100

For more FAQ's on this topic I have some common questions listed on my website.

This was just for the transponder check, not the IFR certification of the pitot-static system. Last time I got one of those it was $250, IIRC.

Vic is correct and your FAA guy is wrong. The transponder certification is an operational issue. It has nothing to do with airworthiness certification.

Again, like Vic, if the aircraft is located where transponder is required, I remind the builder that the check IS required before flight.

Or if you're so inclined, you can get a ferry permit to your local avionics shop to have it done.
