Wow. But NavWorx has stopped doing business. They will surely declare bankruptcy so the FAA will get nothing. Neither will the customers.

The article does not mention the EXP units. There is some difference in opinion whether they are mandated to comply or not. Any thoughts on this?

The AD specifically mentions the EXP units - NavWorx was working on a doghouse fix for them. From what I recall reading, a couple were actually shipped. If you are one of the few that got an updated or 'new' EXP box, you will most likely need to submit an AMOC of your own - but I would suggest that if there are any out there, the hardware configuration and software would be of interest to the remainder of the EXP customer base!

I know that I'm sounding like a broken record these days, but....

Unless you are one of the handful of folks that got an upgraded or new EXP unit, there is no path forward after January for the EXP platform.

For the ADS600-B folks that also have an approved GPS, there is life after January and the AD as long as you follow the procedures in one of the AMOCs. But the reality of the situation, the AMOCs just are buying us some time. With no software and/or hardware support, the life of our units is limited.

Most of can't afford dropping another $2k at the moment and need some time to save for that replacement expense. The AMOCs have bought that time.

For those that don't have an approved GPS to use as an external position source already, I'm sympathetic to your predicament. By the time you invest in the GPS source, there are many other similarly priced ADSB solutions available that probably should be considered.

There is certainly a path forward.. the FAA has not ruled out an AMOC for the EXP.

The FAA doesn't care. For there to be an AMOC, you must have a working solution that meets their requirements. How are you going to accomplish that with the EXP?

It appears to require hardware and firmware modifications, unless you have to have one of the few new ones that got shipped. Having worked with Kyle and Mike since last June getting the current AMOCs approved for the ADS600-B, I would be highly skeptical on getting any hardware/firmware mods approved by a customer of Navworx. I can tell you from my personal experience that if you had a working solution today, it would take a miracle to get an AMOC approved before the AD deadline.

I did ask them about one of the new EXP units and there is hope for them, but Bill modified both the firmware and hardware to support an external gps position source. I haven't been able to get a good count of how many actually got shipped. I suspect that number is rather small.

Still a far cry from ?no path for the EXP?

GordonR 10-30-2017 03:18 PM

Bob,

How do I know if I have got a "new" EXP unit? Is there a serial number or a date of shipment which defines the new ones?

And you say "unless you have a new EXP..." What if I do have a new EXP, how do I attach a certified GPS to qualify for AMOC? The doghouse and v 7.0.0 software was going to do that.

And if we scrape up enough money for another unit, how do we know that they comply and will not do a NavWorx on us in a couple of years? Unless we go to Garmin of course and pay $5K!

What really jacks my jaw is I go out of the way to do business with promising small companies to support them. But I don’t expect to be bamboosalled.

Gonna hang mine on the wall with a sign under it, “$1400” Boat Anchor..... WORTHLESS”

DennisRhodes 10-30-2017 04:01 PM

You can bend over and kiss that 600EXP good-by. Without a working solution and software to support that , there's no chance that anyone can get either a doghouse or any other certificated position source approved. And If you could by some miracle , there would be no support in the future.

Its a shame to pull out a perfectly good UAT which yields 100% acceptable performance reports every time , all due to the comedy of errors that took place in this adventure. I'm going to run mine up to the deadline. Might even fly at 11:50 PM that nite just to prove the point!

It's very unfortunate and frustrating. But also, some warning signs were there, that perhaps Bill was in over his head. For comparison, look at the way GRT, another small company, does business: Your check will not be cashed - not a single penny - until the product is shipped. And the product won't be shipped until it is right.
Also, I STILL don't understand how an ADSB-out using a Transmon or similar device ever got an FAA blessing. (So I think the FAA is partly guilty here, too.)
