172 - avionics
just purchased 172 I lately, foll. instruments not working
properly: vor no signal (narco - all in one units with GS),
ADF gets signal, but indicator not working properly.
Would you bother fixing these or better install moving
map GPS like Lowrance or Garmin?
Any feedback?
thanks
Re: 172 - avionics
I have both a gps and the vor as wellas ADF.
If you do much instrument flying you will eventually be glad you still have the "older technology"
My GPS makes me lazy but it is also a great feeling to cross check to another instrument.
You can repalce the others for probably under $1000 for a rebuild.
Re: 172 - avionics
Werner,
I purchased my 1976 airplane in Sept. On the flight home my #2 comm went dead. Thanks to the Garmin 150, I was able to get home without trouble.
The next day the transponder went intermittent and the "portable" intercom had so much static it was unusable.
In October, I elected to get a new avionics package. It cost a lot of money ($39,000) but they not only replaced the avionics, but the old wiring, and a new panel with better lighting (I always hated the post lighting).
My feeling was that if I got the cessna crap radios fixed, I would end up with fixed cessna crap radios. Luckily, I had money in the budget.
What is most important is that I plan on keeping my Skylane a long time. If this is your plan, I would invest in the updated radios. If you plan on selling the airplane within 5 years, fix what you have.
My 2 cents!

Re: 172 - avionics
Hi Werner: I have a Narco 122 Nav radio, with glideslope, and a Narco Nav11 vor/loc (no glideslope). for sale. Both of these radios are in excellent condition, with recent yellow tags. These should replace your existing self contained Narco's with no problems, requiring about 1/2 hour of install time. Let me know if you are interested.

Re: 172 - avionics
Hello Bruce,
I am taking plane into Avionics shop end of the month to check on the various instruments and depending on what they find, I might be interested in your radio / Vor / loc. I will get back to you on this
once I received the word from the Avioncs shop.
thanks/regards

Re: 172 - avionics
I just put in a new radio stack in 172. Garmin UPS AT stack. I do lots of instrument flying. The CNX80 is the only gps with vertical nav. When the govt throws the switch next month. There will be approaches that will be ILS like off of GPS. Have flow 5000+ miles in past 4 months. Units work great. I am glad I got new radios. A full IFR GPS is a good thing to have in todays world of ADF not being repaired... some are out of service... you can just do the GPS approach into the airport.

Re: 172 - avionics
In response to Mr. Lynn's post-
Having dealt with several of the "new" Cessna 172's I have found the following:
1) Your new Cessna most likely had overhauled instruments and avionics installed at the factory. You can look at all the 8130-3 forms associated with your equipment and in either block 12 or 13 you will see the status of the equipment when is was installed. If you see "Newly Overhauled" then guess what? You paid for a new airplane which had used equipment installed it. Granted, it was returned for failure, inspected, repaired to new tolerences, and tested, but....it's not a new instrument.
2) Cessna decided to cut costs behind the panel and used plastic fittings instead of metal on the vacuum driven instruments. I have found in the field that these fittings do not provide sufficient reliability especially when you're replacing the DG for the third time (after which we were sent a placard which states: " Banks in excess of 30 degrees or continous turns about a point will cause this DG to spin").
3) After Honeywell moved the King radio production to Singapore, the quality of the radio line dropped- most notably the volume knob rheostats breaking the on/off detent.
IMHO the 172K is the best of the whole line. It has the flat steel gear which are stout and easy to replace, the landing light out on the wing, and an airbox that isn't attached to the cowl.
You can get a runout clunker for about $35k. Put 80K into it and you'll have a 172 with your paint and interior, a Garmin stack, and a 180HP engine on an airframe that is more rugged and less expensive to maintain and fix. Then put 20K back into your pocket.
aw nuts...the meter on the soap box has run out again....
Cheers,
RH
Re: 172 - avionics
Roger,
I just had a discussion with my A&P. While complainng how often I need to fix things, he assured me that my 1973 C-172M has fewer repairs than the newer planes. Roger, I guess you have had the same experience.
By the way, regardless of how more frequent the newer planes need repair, that really doesn't soothe me one bit! Although I may appreciate my good fortune at those times, I do not feel better because of the misery of others. So, what to do. I decided to get my prop balanced to lessen the vibration in the plane. But what else can I do? Got any suggestions....
