Edo-Aire HSI

[721lp]

Guys,

 

I have an Edo-Aire HSI and the glideslope flag will not "unflag". I talked to one repair facility and they wanted to do a full overhaul to the tune of almost 4,000. It was just o'hauled about 3 years ago with not a lot of hours on it. Any suggestions for a RELIABLE, honest repair shop that will only repair the problem and not try to take me for a ride....?

I just talked to Bob Bramble on the phone and he said my problem was probably just a dirty movement in the GS flag. He seems like a very knowledgable guy and honest. Thanks for the references.....

Take the HSI indicator out of the panel and shake it by hand several times. It will likely solve the problem. I found this works for half the gyro/indicators problems.

Jose, I will try that first.....but gently, hahah

Sent HSI to Bob Bramble yesterday........will report when I get it back.....

[721lp]

Bob called yesterday and said that the meter movements needed cleaning, that was all.....$250 + shipping.......I'm pleased, so far. Will report on the HSI when I get it back in the plane.......

How does this stuff get dirty?  Aren't these things well contained?

[721lp]

Since I work in INDUSTRIAL instrumentation, I feel i can answer this question. Over time, small dust particles and general wear of the jeweled movement will generate enough dirt to cause problems in ANY mechanical meter movement. I see this almost every day. It is becoming more rare though, thanks to solid-state equipment......meaning LCD dispalys with no moving parts. But, as long as we have mechanical movements, this will always be a problem....

Well, guys......Bob Bramble worked his magic on my HSI. All works beautifully, and for $299. A lot less than I was quoted from a few places, who claimed that if they opened it up, it had to be overhauled to the tune of 3k. I would wholeheartedly recommend him for any instrument problems.

A good shake would have cost you less.

[721lp]

Jose'.....I was afraid that a good shake might have cost me more than I could afford....hahah

[Piloto]

OK, OK, OK

[721lp]

How in the world did that get in there 3 times?????

[721lp]

Well, guys, as luck would have it, my good old Edo-Aire HSI had another problem after i got it back from Bob Bramble. He fixed the sticky G/S flag, but then the CDI was binding on the gyro. So, I called Bob and he said send it back to him, which I did. He found some problems in the gyro so he sent it to a friend of his in Texas. He is overhauling it for about half what the "west coast" shops wanted , plus a 1 year warranty. Still costs 1395.00. But that's better than the 4k price I was quoted from the other guys. I will let you know more when I get it back in the plane probably this weekend.

Sorry to hear that. It's quite a pain to shell out all that cash only to find it wasn't the only problem. Good luck with it!

[721lp]

HSI reinstalled.....smooth as silk now.

[721lp]

Ohhh.....by the way, Bob Bramble sent it at his cost to Georgetown Instruments, Taylor ,Tx.......the guys there are good..

I think the dust gets in because this is a vacuum gyro....Also i think this is the same as a sigma tek 1u445 and will not work with the garmin avionics... Had one and couldnt understand why it wouldnt work w the garmin...Until I spoke to garmin... Replaced it with a Sandel 3308 ... 

[721lp]

Mine works with my GNS430. I'm not sure about Sigma-Tek.
