Mooney Corrosion

[@blancolirio]

Excellent! Thanks Mark! Before you buy a plane, get a pre-purchase inspection and make sure you have a hangar 1st.

[@kasm10]

Juan everyone says get the ppi but last I checked a&p was booked 2 months out!!! Can’t let a deal hanging that long

[@darrylday30]

Thanks Mark. I’m looking for a good (not corroded) M20C up here in Canada. I’m an aircraft mechanic but I’ve never seen the skin off a Mooney before. I’ve read the Bulletin and video really helps bring it alive.

[@BrittaProducts]

Just to be clear, this inspection is easy to do by removing the seats and interior side panels. It takes just a few hours. Make sure you do this as part of any pre-purchase inspection.

[@Orvillehuit33]

Thanks Mark, your videos are always just excellent for educating owners and future aircraft owners.. I hope you don’t quit on this endeavor.

[@skywagonuniversity5023]

I hope so too

[@jts4233]

Nice content! - i never saw a Mooney naked - thank you!

[@sebastiansuarez4838]

Excelent video Mark! I want more 206 videos from the inside of the cockpit! Greetings from Bolivia 🇧🇴!

[@davidnelson4707]

Thank you for that video, a AD should be raised on that problem.

[@skywagonuniversity5023]

There are very few that need this level of work and it is being considered as an AD. There never been a structural failure due to this though.

[@davidnelson4707]

@@skywagonuniversity5023 while there hasn’t been a recorded failure ,it’s important to stop any corrosion in a aircraft and high light it to owners and maintenance organisations to monitor a impending issues. We can’t just wait for a failure and then bring out a AD .

Thank you mark I learned more in the last six minutes than I have learned in the last six days thanks skywagon university 👍✌️

[@skywagonuniversity5023]

Great to hear!

Thanks a million Mark, will be waiting for the Polish military trainer video. 👍🙂

More please Mark !

Big thumbs up Mark!

Thanks. I have 8 strikes in my thumb

Autocorrect!!!! Stitches.

[@tow.JanWinnicki]

Please tell your video person that zooming in means a lot more than taking a half step towards the plane. I really wanted to see the extent of corrosion on the tubes. Cheers. Serwus!

[@davidcampbell2845]

Brilliant video as usual - thanks

[@flyingfortressrc1794]

Great information. Thanks 👍

[@rwlewko]

Mark, there's a question I have pondered for a very long time: when there is ferrous material and aluminum in the same structure, as aircraft frequently have, what prevents galvanic processes from acting on both metals where they meet? Surely there is steel to aluminum contact somewhere in the wings or fuselage. I'm sure that engineers have a few standard ways of handling this. Do you, or any people close to you, know how this is done?

[@skywagonuniversity5023]

Very good question. The only thing that prevents an electrolysis occurring where dissimilar metals meet is dryness. If they get wet, they will corrode.

[@rwlewko]

@@skywagonuniversity5023 From my reading about boat building techniques I saw that they use beams that are aluminum bonded to steel through a high energy process that bonds the materials at a molecular level so that the aluminum is attached to the aluminum and the steel is attached to the steel. Unfortunately the pieces I saw looked much too heavy for use in aviation. I just wondered is such processes are used in aircraft. Are there any mechanics who want to add some input?

[@edstoybox]

Great video!

[@skywagonuniversity5023]

Glad you enjoyed it

[@joshualorenz4665]

Nice video, good explanation

[@skywagonuniversity5023]

Thanks.

[@tpsu129]

How about a video on N6442Q, Mark?

[@skywagonuniversity5023]

It's not really a sales video thing that I do, it is more about what the differences and features of planes are etc. The 67 F model I have for sale is just an old project plane that needs a new home for $25,000.

[@tpsu129]

@@skywagonuniversity5023 don’t think of it as a sales video. Think of it as a helpful tips video. Like, how would someone on the East Coast be able to get it to their home field, etc.

Never be concerned with Americanizing that charming accent!

[@skywagonuniversity5023]

OK.

[@danielconte3244]

Excelente video...very didatic

[@utah20gflyer76]

If you are going to park outside get a good cover, it will prevent this sort of corrosion and keep your windows clear and in good shape. For 600 dollars you can prevent 20k in future work.

[@markbattista6857]

Hey Mark , do you know if the tubes used are Renyolds 531 as used on the Hawker Hurricane and others & are they braze lugged or welded ? Thanks again

[@skywagonuniversity5023]

I'm not sure what the tubing is but they are welded.

[@markbattista6857]

@@skywagonuniversity5023 Thanks Mark

[@SkylaneGuy]

It’s 4130 chromoly steel. More equivalent to Reynolds 520 which is a proprietary name. And they gas welded back then.

[@markbattista6857]

@@SkylaneGuy thanks Craig

[@steprob8692]

Climate and storage history of this example?

[@skywagonuniversity5023]

I think it had some east coast outside parking time before it's new paint and west coast hangared time.

You are always so informative, thanks!

Damn I thought for sure we were gonna get that debonair video that posted

[@skywagonuniversity5023]

Just waiting for weather, timing, debonair, owner, airport work business etc schedule.

$10,000 is 10 boat bucks or one airplane buck.

[@skywagonuniversity5023]

Or two tanks of gas?

[@AC-jk8wq]

Not too unique to Mooneys… all planes made of metal have corrosion issues to look for during the PPI… both aluminum and steel… Unique to the older Mooneys was the insulation that was used, kept the tubes from staying dry…. Nice video! Go Mooney! 😃 - a -
