ADS-B STC for the AXP340 Status Update

(AXP340 ADS-B STC Status Update - 12 Feb 2015)

The FAA has just issued TIA which clears the path for the next step on the ADS-B cert.

For those folks who want the summary story - we could have STC approval within a week.

For those folks who love the details, we have the following steps to knock out:

1. Use the signed TIA to allow a FAA designated inspector (DAR) to perform a conformity inspection of the gear and airplane - presuming he is available, this takes a few hours. We're checking on his availability right now. Could happen today, could take a few days.
2. Once the DAR has signed off on that inspection, we perform the for-credit ground tests (a few hours in duration) then perform 3 flight tests (should take 1.5 days presuming weather, airplane and equipment all perform as expected). We've dry run all those flights so we're highly confident.
3. Send the FAA a quick thumbs up note when flight test is done.
4. FAA processes a few other paperwork items then issues the written STC.

Due to the significant snowstorm pounding New England, the FAA did not open their MA Cert office today.  So, the expected TIA I talked about on the 5 Feb post has not (and likely will not) be issued today.  We hope this is just a one day slip due to wx.

For those installations that already have a 340 then it's just paperwork.   For all those folks who are flying now with a 540-340 combo and ran that FAA test to see if they were ADS-B compliant and got a yes, this STC will provide the paperwork to supports ADS-B compliance.

Does that answer your question?

It's really close.    The FAA informed us this morning they intend to issue the TIA on Monday.    That gives us approval to get the unit and aircraft through FAA conformity (an inspection that takes a few hours and should be completed on Tues, 10 Feb), which then clears us to perform the official for-credit flight test on Wed, Thurs, Fri weather permitting.   Presuming the flight test goes as well as all the dry run flights did, it should then be a matter of a few days for the FAA to issue the STC.

No, there is no need to delay for the  ADS-B OUT STC. That has no effect on function, and no effect on certification until 2020.

Hi Steve,

The "joined" date is when you created an account here on this message forum.  The message forum has no way to know when you purchased or installed your Avidyne equipment.

As usual, I am confused. Will the "new" STC for ADS-B Out include a speed unit to provide the airborne signal or will we still have to install some sort of "Weight On The Wheels" switch to tell the world when the aircraft is airborne?

Happy Skies,

Old Bob

Hi Steve, 

As many readers know, we're in the end game in the pursuit of a new STC that enables one to take ASD-B compliant credit for the AXP340 Mode S Transponder.

This permits the AXP340 to take GPS input from the IFD540, R9, G400W, G430W, G500W, G530W units and meet the requirements for ADS-B Out performance.

All data has been turned into the FAA and they have largely delegated signoff authority back to us.  There were a number of actions to be taken and they seem to have been largely completed now to everybody's satisfaction.

We *should* have signed off STC authority sometime in January.
