A little Lesson In Propellers


Cody Stallings

Recommended Posts

I Normally deal with these issues with customers Propellers, But this time it was mine.

Recently Purchased my new To me Mistress N252A.

Propeller was doing everything it was supposed to do. Running smooth, actuating well an no grease leaks.

But it has been holding down the front of the plane for 18 years, with that being said me an my guys decided to open a spot for it in the shop.

Just wanted to open it up an give it a good inspection an a fresh set of Orings an Gaskets. 

Went down hill pretty Fast after removing the cylinder. It was very clear why it didn’t leak grease!!!....lol

After a week of waiting on parts, We started the resurrection on Friday.

Im happy to report, it went together very nice( New Parts usually do that for some reason), short of wiring up the Anti-Ice leads it’s ready to go Back to the Nose of N252A

It sure make a strong case for more frequent visits to a prop shop.

I’m going to venture a guess this Propeller had a grease leak at some point that went away.

Owner was probably really happy it stopped leaking too..lol

Cosmic event... Plane selects the right owner!

Great pics, Cody!

Got a video of the white prop with the engine spinning? That looks a bit more visible to people walking by...

Best regards,

I don’t have any pics or Vid yet. It’s still bolted to a steel table.

What are blade paddles? Do we really need to placard it on every blade. Also, is the McCauley sticker required to be replaced after a overhaul?
I personally don’t like my propeller to look like a racing car.

Blade Paddels are a device used on feathering Propellers when they miss the startlock during the engine shut down.

They are used to manually turn the blades.

When they are used on a blades with deice boots, the boots tend to get shorted out due to smashing the elements inside.

Does it need the blade paddle stickers on all 3 blades?.....Yes Sir!!!

Put the sticker on one blade, an in some people’s mind that means the other two can be moved with a blade paddle. Just not the one blade with a sticker on it.

 

As far as the McCauley stickers go, whatever the O/H Parts Kit contains is what goes on the prop.

Now, the Owner can elect to go with or without, totally his choice.

Being in a Repairstation is completely different.

It is great having a fellow Mooniac service your prop.  Cody did mine a couple years ago then flew his F model to my airport and balanced it for less $$ than when I had it done in Oklahoma a few years earlier.  I really appreciated the extra time he spent educating me on props and the right/wrong terminology to use (IRAN versus OH).
