Maybe.

Or maybe they're just accepting that publishing a rule (for failure to meet a certification standard) against a product that is not certified might be an endeavor that exposes certain thorns that are better left buried.

Especially in a time when the FAA is encouraging the use of non-certified products in certified aircraft.

Looks like this is mostly supporting and background documentation from the FAA's side. Unless I'm mis-reading it, the broad emergency order of suspension has been lifted but there is still an Unapproved Parts Notification that is effective on the -0012 and -0013 units that use software version 4.0.6 (SIL 3) or any future software version that incorporates SIL 3.

Looks like there was a recommendation to include the Experimental devices as well! Buried in one of these documents.

There was an attempt to include the experimentals in the AD, but they can't do that, so the experimentals were covered under the Unapproved Parts issuance.

That makes sense since the AD's don't normally apply.....

And the data dumps continue - more added today and possibly more coming.

As Paul Harvey would say - "The REST of the story" is now coming out. Reading the technical rationale behind the FAA's decision to TIS-B changes sheds some light on what happened, why, when, and who knew about it, and when. Some emails between NavWork and the FAA are also included, which gives some insight into the situation as well.

One of those e-mails details their expected customer blowback from the -12 and -13 units not being able to continue receiving TIS/FIS traffic due to the SIL requirement change...based on the expectation of reception due to functional compatibility instead of a compliance certification.

I am thankful to have my unit back and working - and that I installed it using a certified position source (430W).

Hopefully, all I get is updated software that transmits SIL0 when the internal (non-certified) GPS is used and SIL3 when connected to the 430W....and display port 2 fixed!

Ralph,
Unfortunately, we who are using the 430W as a position source are still screwed. The AD is out. I don't know how many Navworx deceptions I can put up with (or afford). Here's the pertinent info about the 430W:

Quote:

Some commenters stated or implied that other external GPS sources, such as the Garmin 530W, the Garmin GNS 430W, the Garmin GNS 480, and the Garmin GTN 650, are approved for installation in the ADS600-B. Contrary to any documentation these commenters may have from NavWorx, the only FAA-approved external GPS source is the Accord NexNav mini P/N 21000. Documentation of this is available for review in Docket No. FAA-2016-9226.
