YAGQ (Yet Another Gyro Query)
It looks like the AI on my Cherokee finally bought the farm. My
friend who just flew it on a cross-country said it laid over and died on the way. So, the question is, used, overhauled, or new? Any thoughts on this? Brands to get/not get? I'm leaning away from overhauling the gyro, since I don't know how long it's been alive. I'm pretty sure it's old and hasn't been touched in over 20 years. Just wondering what folks think. I'm currently finishing my instrument training and plan to use it for some light IFR cross-country trips later on. -Cory -- ************************************************** *********************** * The prime directive of Linux: * * - learn what you don't know, * * - teach what you do. * * (Just my 20 USm$) * ************************************************** *********************** |

My AI failed at 300 hours. Had it overhauled and it's running strong at
900. No recommendations here though. Just don't know enough. wrote in message ... It looks like the AI on my Cherokee finally bought the farm.

Light IFR cross country can turn into hard IFR cross country. Consider the
importance of the instrument and then decide whether it would be better to buy a new one or overhaul a 20 year old AI. I think you already know what you should do.

I had a new one fail at 160 hours. Wanna buy it for overhaul?

I'm as frugal as anyone (c h e a p is the word my bride uses) but, cutting
corners on something that will kill you is not good.. I do not overhaul or buy a used primary gyro, altimeter, or compass... The savings aren't more than pocket change, and the downside can be a long ways down... Now having said that, when it comes to upholstery, radios, gadgets, etc., cheap is good!

Light IFR cross country can turn into hard IFR cross country. Consider the importance of the instrument and then decide whether it would be better to buy a new one or overhaul a 20 year old AI. I think you already know what you should do. Well, gosh, what should he do? When our DG failed, we figured the AI was the same (unknown) age and bought a new instrument with a vacuum failure flag. The new AI failed less than 50 hrs later. It was replaced under warranty, of course, and has been OK since. I have friends with overhauled AIs which work perfectly for hundreds of hours So tell us, what should Cory already know that he should do, because having gone through 2 instrument and 1 vac pump failure in 1000 hrs of flying time it's not so clear to us? FWIW Cory if you don't have a vacuum guage in your primary scan I'd consider a new instrument with a vacuum flag on the face. But, it's just not clear to me that new is necessarily superior to a good O/H. A lot of people seem to like Kelley Instruments these days. Cheers, Sydney |

A lot of people seem to like Kelley Instruments : these days. While I agree that when toddling around in the soup, you don't need anymore challenges, I'm thinking that the additional $150 overhead for adding a flag needs to be reconsidered. I've got the vacuum gauge, albeit on the far side of the panel. At some point, however, one needs to say, "enough is enough. I won't get raped any longer on aviation price gouging." Having the flag doesn't make the gyro work when it breaks, just potentially alerts you sooner. Dunno... need to think about it a bit more. Don't even get me started on the $150 price overhead for getting a lighted one.... -Cory -- ************************************************** *********************** * The prime directive of Linux: * * - learn what you don't know, * * - teach what you do. * * (Just my 20 USm$) * ************************************************** *********************** |
