Possible AD for certain NAVWORX ADS-B Units
Shamelessly plagiarized from another forum: "It looks like there is an AD coming on the Navworx ADS600-B -012, -013 and the EXP 8013 ADS-B Transcievers. The proposed AD is located here. If you are impacted, you have 60 days to comment."

Hmmmm. This isn't great news. Perhaps the Navworx folks can provide some back story? I'm really hoping to buy two of the -EXP units next year.

I'm impacted
The Navworx 600EXP has been installed in my plane about three months. I'm already spoiled and don't want to think about flying without this traffic and weather. Is this just a software issue, something they can rewrite? It looks like this AD will effect about 800 of their ADSB units. Hoping Navworx will chime in today!
Edited: I went to Navworx site and there is information there regarding UPN or unapproved parts notification... what ever that means... and at the end it states to write to the FAA administrator or your congressman.

I'm upset!

It sounds like the FAA's beef is about the GPS accuracy (which they issued a certification to). For those who have a certified WAAS position source, I would presume that this would "fix" the issue, but I haven't heard this mentioned anywhere.

I hope this gets worked out - I was planning on buying one of these next year.

NavWorx Proposed AD
You have to wonder if the Big Guns producing Expensive ADSB products are working behind the scene to Torpedo NavWorx.

I hope it gets solved too. I've got a 600 Exp still sitting in th? box waiting to be installed in January. :mad: I don't Know exactly which mod?l, I just Know it 's a 600 Exp.

I've contacted NavWorx - no answer on what they plan to do for their customers - I asked a bunch of pointed questions.

They did request that I comment on the AD - which I did.

Recommend all y'all do the same!

I have the model of the 600-B which is affected, but haven't flown yet.

Unfortunately, I don't know about the particulars to provide comment! Do I take Bill's side and argue/comment against the FAA findings?? Is that in my best interest? I know removing or in-opping the box isn't the long term solution, but where do we go? - I need to know the consequences....

I've read the proposed rule and Bill's response, and it sounds like a he said/she said that is actually brought about by the software upgrade. I'm hopeful that a new software update will fix the problem.

From what I understand, the software upgrade was at the FAA's request to make the device's accurate. The fAA originally certified the functionality with the non-certified internal GPS - then told NavWorx that they had to put out the 'other' SIL to be accurate - then they can say 'bad SIL, no data'. The FAA put NavWorx in this spot by certifying the functionality initially then changing the documentation rules - to fit their scenario.

Again, my understanding from reading both the AD in the FAA website and NAVWORX response on their website.
