I've got an Aspen E5 that's rebooting occasionally. Configuration includes an NGT9000 and IFD440. The E5 reboot is preceded by a "429 Data Not Rcvd" annunciation on the 440. Looking for any suggested diagnostic and/or corrective actions. (My avionics shop is looking into this too.)

Thanks in advance!

My gut would say that the 429 Data Not Received is a symptom of the E5 not sending data to the IFD just before it reboots.

matthewsjl is correct, it's not a diagnostic message it's just letting you know it lost a signal. I had one of the first E5 installs and had some other issues (cable length). My original unit would occasionally reboot both in flight and on ground (got same message). When I went in for the cable fix they replaced the E5 also and that problem went away. Unfortunately had a new glitch a couple of weeks ago and am waiting on a replacement unit.

Check that you have the correct configuration on the IFD for that 429 input. If that is not the problem, you may have (as previously mentioned) wiring quality problems. Your IFD is not getting ADAHRS data from the E5.

I am also having Aspen E5 reboot issues and have reached out to the OP and Flybuddy:

Earlier this year I took the plunge and did an avionics upgrade that included a new avidyne ifd440 and a new Aspen E5.

Unfortunately, since then my new Aspen E5 has been performing poorly in the 9 months since installation....I am looking to see if other Aspen E5 customers are experiencing similar issues to help find the root cause.

While Aspen has been responsive in trying to resolve the issue I will describe below.....I am posting here to try and get the word out to see if others are experiencing the same problems with the Aspen E5 to see if the community can shed some more light on what is going on with the Aspen E5.

**** So, here goes ::::: I'm now on my 3rd Aspen E5 unit since Feb 2019.

I've had 3 in-flight E5 restarts ( 1 on each E5 )...the E5 just goes blank and reset as if it was normal:

1st reset) On final approach to rwy in Feb - approach power/RPM, gear going down:::E5 replaced by Aspen in Mar

2nd reset) In cruise at ~8k ft in Sept - cruise power/RPM:::E5 replaced again by Aspen + New (blue) shielded RSM cable Nov - cable length less than 12 feet.

3rd reset) On departure at ~5k ft in Dec - high power/RPM:::Logs downloaded and sent to Aspen. Logs seem clean to me but Aspen has yet to review and make a root cause determination

Some background info:
- I've flown about 80 hours since original E5 install
- E5 is just connected to an ifd440 and an Stec-30 via the Aspen ACU
- I have the original 910-00003-002 RSM (E5/Top Mount) installed
- I get no indication on anything in the plane that a reset is pending...ie, dim lights, GPS error, etc
- Seems that there is no correlation in the events for the in-flight reset
- I reviewed the logs sent to Aspen....I can see nothing other than what appear to be normal bootups
- I have looked at the disgnotics page and see nothing out of what I would expect to be normal
- E5 MAP software was 2.10 during all of this
- E5 has a backup battery but never "goes to battery", ie like in a loss of power situation
- There is no ADSB-In info being fed into the system...I use a portable stratus and ipad/foreflight for weather/traffic.

If anyone else has any ideas or has experienced any E5 issues, please feel free to reply.

There have been lots of E5 / Aspen posts lately and just wanted to get an update out there.

Aspen delivered an updated E5 ( with the new 2.11 software ) to my shop and was able to get it installed today.

I have just 30 min on the new unit but no issues so far....Aspen has been responsive to the issue and feels like we are moving forward.

Two thumbs up on my ASPEN Max. Just slipped right in (upgrade), and is working well.
