500 magneto inspection

[DOC]

So the mooney I am purchasing is in pre-buy.  I get notice that the is a SB about a recommended SB on a 500 magneto check at 1562 TT.  It will cost 1K at this current shop where the prebuy is taking place where most places charge 2K.  Am I being taken to the cleaners?  This is a 2000 M20R Ovation 2.

If you are referring to SB643B ?.

 

Why, as the buyer are you being asked to pay for this?  

[DOC]

I am not sure why I am being asked to pay for this other than 1. They are simply trying to get me to or 2. Since it is "Recommended" and not manditory, the brokerage co. who owns the plane doesn't feel they have to.

If they are Bendix mag's plan on spending $650/mag to be IRAN'd plus A&P costs for removal and re-installation.

[BigTex]

If this is a pre-buy, I'd not pay for anything other than the cost of the pre-buy and any agreed to expenses the seller incurs.

 

Also, if mags need inspections, I'd recommend only sending them to folks that specialize in mags.  I'd never let a local shop IRAN or overhaul them.  If you purchase the plan we can provide recommendations on where to send them.

This brings up a good point and I almost always follow mike busch advice about sending the to a mag shop but why not have the local mechanic IRAN them if there qualified.

I've been having Chuck at Dodge Center Aviation do my IRANs on the dual mag, but I believe he is a sharp mx. He understand the system so what exactly would a mag specialized shop do differently?

One other point my buddies 2008 Acclaim had a mag fail at 2000agl in the soup a week ago. The cause.....the plastic gear inside sheered it's teeth. The cause the small little brass plug with the tiny air hole in the center about the size of a pin hole became plugged and since air could not move out of the mag the ozone levels increased and turned the gear and ugly yellow and it became very brittle and failed. Ozone is created when ever there is a spark and there's lots of sparks in a mag.

The hole can not be inspected without removing the mag from the engine as it's on the bottom. This hole should have been on the top so it could be inspected. Bad design, but given how expensive it is for the mfg of the mag to chance the design do to the FAA ridiculous regulation, I can see why it hasn't changed.

Get your mags inspected often. Sooner than 500 hours on turbos.

Thanks guys. Due to your advice I contacted the Seller and they agreed to pay for the mags.  This is being done at a Mooney Service Center in Atlanta area DLK Aviation.  I have heard they are very reputable.  Any opinions?

[DOC]

Also I apologize for my lack of knowledge, but what does IRAN stand for?

Inspect Repair As Necessary

Doc,

A couple things to consider when purchasing a plane...

(1) pre purchase inspection independent of the seller and his previous maint shops. Good for your financial health.

(2) transition training with a Mooney knowledgable instructor. Good for your plane and your physical health.

(3) using an MSC or MAPA resource should get you close, but final decision/ responsibility is still yours.

(4) all ADs should be complied with for airworthiness. Service Bulletins are not required, but should be considered seriously. Again, this is the help you hire for the PPI.

(5) where are you going to keep it and who will maintain it for you there?

(6) If all goes well, who will do your transition training?

(7) are you instrument rated?

Best regards,

there is an abundance of mooney knowledge on this forum.   I'd bounce questions off these guys about anything I wasn't 110% sure about, especially at your stage of the game.

[DOC]

Thanks again, trying to avoid the landmines.  I am looking for a good "Mooney" instructor.  Does anyone know one that would travel?

I do Doc, however I am booked thru mid February. If that schedule would work, PM me and Ill be happy to supply references, etc.

 

Mike

[DOC]

Thanks Mike.  I will keep that in mind once all the  dust settles.

[carusoam]

Where are you located?

Transition training and Xcountry delivery makes a good couple of days of flying.

Do you have mooney experience already?

Best regards,

My mother always told me that if I didn't have anything nice to say, then I shouldn't say anything at all...............

Doc, I can do limited travel.  I am a CFI in Atlanta.  Feel free to contact me via PM.  I would be happy to talk with you about my Mooney experience and about what your needs are.

Doc, Joe,

Spend lots of time in the circuit leaning proper speed control. More than a fair share of long body Mooney's have had engines and props replaced because the pilots can't land at the correct speed. Any one can be taught to fly it cross country, but you still have to land it.

the 500 hr is not a big deal. A competent mechanic can do each mag in 1.5 hours, plus R&R time. Unless the mag has been neglected, the first two 500 hours rarely require parts changes. That's the whole purpose, to catch and correct things before problems arise. This applies ONLY to Bendix mags.

 

Slick mags rarely go 500 hours without problems, since they forgot how to build mags in 2006. With Champion now owning Slick, the problems are worse. 250 hours is the new recommended inspection interval for Slicks, due to a host of problems such as bad: carbon brushes, point cams, distributor block bushings, intermittent coil tabs, loose rotor tangs, and so on. This is compounded if you are using Champion's spark plugs, which have unstable resistance values. Or the fine wires that have unstable, increasing resistance, pllus cracking electrode insulators.

Interestingly a few pilots are switching the Slick mags out for Bendix. It's a good sized job but it eliminates the Slick mag failure problem. We had 4 failed Slick mags in the shop all in a row last month. The last one was the boss's Piper Arrow. It was 250 hours since new.

Byron, I didn't know you had a repair shop and a boss with a Piper Arrow??!! I thought you were an airline captain. Is this some sort of forum software bad mojo? 

[jetdriven]

I have been working at an airplane repair business for the past 3 years on days off.

[philiplane]

As a pilot and aircraft owner, I only use Bendix mags on my own plane. 

 

As a mechanic, I'm fine if people want to use Slick mags. I have one kid still in college and Slick mags keep me busy....
