Corrosion on yokes.

I will be at the paint shop next month, and while its in paint, I am having yokes sent out for leather. 

But your green paint job looked pretty good. At least here in pictures . . . Do you have sketches of what it's going to be? Or are you waiting to reveal the finished job???

Thanks - but paint was in decent shape, but not great.  

I have sketches - but its a surprise - :-)   I will post when I have photographs - hopefully in March.   It will be a whole new look - and maybe even a new tail number if the FAA processes my request soon enough.  You won't recognize me in a new colored mooney, with a new tail number, and maybe I will even wear a groucho marx noes.  You will never know its me!  Other than the 4 blade prop as the one give away.

Its at weepnomore right now for (preemptive) reseal plus lr tank install - plus I got a new interior by Bruce Jaeger and new leather by SCS - so I will retrieve that later this week hopefully weather permitting - I will post those pics when I get it....

And this is how the professionals do it, once and done:

 

Upon receiving, the yokes are visually inspected, photographed and the owner is notified of any unusual conditions.

• The yokes are disassembled, abrasive blasted and metal finished.
• Minor pitting is epoxy filled, cured and finish sanded.
• They are chemically cleaned and out-gassed in our ovens.
• The yokes are sprayed with 2 coats of TGIC Polyester powder and oven cured.
• Yokes are removed after oven curing and allowed to cool to room temperature.
• Once cooled the yokes are hand sanded to remove any minor imperfections.
• They are then cleaned and placed back in the oven until cure temp is achieved.
• The yokes are removed, sprayed hot with 2 coats of TGIC Polyester powder and then  placed back in the oven for final curing.
• Yokes are removed, allowed to cool, reassembled, inspected and released to shipping.

This is how the professionals do it, once and done. Sort of like tires and batteries, you only get what you pay for.

Mine were refinished at a different shop in Cleveland for about $500.

Turned out Mooney was so impressed, they tried to get them back to put on their new factory floor Acclaims.

So far, I have been able to hang on to them.

Which professional? This a place you send them to after your mechanic removes them?

I was searching for steering wheels I saw on cars in old movies and ran across this guy. While looking at his web site, I was surprised that he does airplane yokes too.

I have no first hand knowledge of this guy.

I recently addressed the minor corrosion on my pilot yoke by sliding heat-shrink tubing over the handles. After shrinking the tubing and trimming the excess, it doesn't look bad and the rubber grip feels quality, even though it is not.

Here's an idea - what about upgrading the yokes to an aftermarket product? Surely there are manufacturers who build a yoke that will fit (an be approved) for our Moonies?

Unfortunately, you’re responding to something posted over 6 years ago. I don’t think I’ve seen DavidWH since I’ve been a member.

Not sure of the condition of my left side yoke, someone previously covered it with bicycle grip tape.

Sounds like an option for covering over the corrosion and improving the appearance, but that doesn't deal with the corrosion.

You are correct. The corrosion wasn't bad - what do you think will happen over the years to my yokes if I just leave it as is?

Can’t tell what will happen…

But, in the past…. There has been concern with the strength of the castings…

Corrosion, can instigate a crack…

A crack can lead to the yoke breaking, and then falling off…

 

There is a recent example of a pilot on the internet that lost his Mooney’s yoke while flying…. Possible YouTube radio recording?

There are lots of Mooney yokes that have corrosion issues where the hands rest… 

Salty palms apparently initiate the corrosion…

Serious cracks have been found near the bolt hole for the bolt that holds the yoke in place…

 

The FAA didn’t like dip coats for their ability to hide cracks…

Most 60s Mooneys were nicely dip coated yokes from the factory…

 

Not sure how well leather yoke coverings protect the aluminum casting from corroding…

I really looong accident chain, that has low probability of occurring…

But, proper cleaning and preventing corrosion is always a good idea…

PP memories about stuff written on MS only…

Corrosion doesn't get better. 

Here's one post about yokes (there are probably a lot more):
