One VERY good reason for owning a 337!

[Ernie Martin]

Larry:

Installation for both units seem to be a snap: power leads and pitot/static plumbing are the only connection (in one the magnetometer is external, so that's one more connection). The reason for such few connections is that most everything is inside the housing. So the real issue is fitting the box in your panel and the 337 approval (or some clever way under the panel in a non-permanent way, without connections to the bus, so you can argue that it's like a hand-held GPS). I like the approval route better, and would like to think that you can find a sensible and courageous FAA guy who'll sign it.

Carlos, the Seneca`s owner, had the unit installed 20 months ago, and he has had a hassel free operation, considering that he flies a lot!!!. Remember the unit shows altitude and speed all the time, plus more Nav information I can not recall.

A few years ago I simply bought a backup AI. Not as good as the EFI, but cost 2500 installed in those days - the common electrical type - works fine and gives me a nice feeling of security. if the backup goes belly-up, I have the electrical and it's certified, etc.

Talked with Sheila at Blue Mountain. The EFIS lite is not yet shipping. She also says the US FAA will not permit non-certified instruments in a certified airplane. Courageous FAA guy reminds me of Herb Harney who waited nearly 7 months for his approval paperwork on a Garmin 530 install.

It does not sound promising, for us.

We all understand the need to 'prove' these instruments are reliable and safe... So I understand the FAA's resistance to use of non-certified instruments....

But it is truly sad that (as in the case of the P210 pilot) that people cannot legitimately aquire this capability - if even under a 'Not for IFR Flight' restriction. At least then, if the certified goes bad - they have 'something' to bring them home... Like I said earlier in this thread.... I'd love to have a non-certified instrument as a plan 'C' backup - because if the Vac and Electrics are gone - an internally battery backed unit like this could save your life. It's a shame that regulation, red tape, and the threat of legal liability claims have taken that away from all of us - or at least those of us who are afraid to violate the FAA regs.

In a commercial application - I totally agree. = must be certified.
In a private (certified or experimental) application - it should be your choice.

If/when you go to sell your certified - as long as the buyer 'knows' that the instruments are non-certified - it should not be a problem. Why deprive the public of this new technology? Why make it so expensive from the certification process that the general aviation community can no longer afford it? It's a shame.

It is interesting, you can get a Sierra Flight Systems version of the Chelton EFIS, for experimental aircraft, for $24K. The same thing, certified, is $54K.

I submitted for a field approval of a Dynon D10A on a 1975 FT337GP N1049D, the installation was minimal hassle and so was the approval. Yippeeeeeeeeee

WOW - that is great news!

Can you share the paperwork, and the process used to add this?

my email address is pschmitz@starband.net

If it was approved for you - I will definitely go that route.

Thanks for writing!!

Jack:

I'll be rude . . . how much was the install and cost to get it field approved?

Thanks,

Well guys in this day of modern technology I can't email the paperwork, but would be glad to send a paper copy.

Aside from the obvious cost of the unit itself, I spent $53.00 with aircraft spruce. Have an AP/IA so signed the form myself, took a day to do the paperwork and the install.

My email address is wybenga@excite.com

Good luck

Dear Sirs,
I have seen the Dynon EFIS installed in two certified aircraft here at Birminham, AL. Both installs were done by the MERCURY FBO under their repair station, with direct approval from the local FSDO.
Placards reading "Not Primary, For Reference Only" were required, as well as the retention of a TSO approved conventional attitude indicator in full view of the pilot. The approved indicator was to the side of the EFIS which was directly infront of the pilot at the top of the panel. A form 337 was required and filed.
I will attempt to obtain the form 337 and post it, as I intend to add EFIS to my 336 as soon as funds permit.
Regards
James T Grant
