...::: AIR LIFT M20K 252 :::... (Rigging)

[Yetti]

I would strap the plane to a pallet using the tie down points.  Then lift the pallet.  If you are not wanting to damage things.

Jack points. Tomato. 

They might work if the plane is upside down, which I’m guessing it isn’t.  The OP is talking about slinging the plane to lift it.

@1980Mooney nice work digging up the videos!

I spent an hour with no success…

Thank you.

@M20K 252 when you check in there is a bunch of new information since your last post…

We have three Jack points… but that isn’t exactly a lifting spot for an overhead lift…

See the most recent videos from @1980Mooney snowy fields…

The engine mount is a pretty strong device for lifting…

The lift eye on top of the engine should be avoided like the plague… it looks much better than it actually is… great for lifting the engine, but not strong enough to lift the plane underneath it….

There is an engineering group at the Mooney factory…. That may be a great resource for a consult…

 

PP thoughts only, collections of info from other people…

If you think outside the box you will see what I am talking about.

 

[carusoam]

You should see the size of the box where Clarence does his best thinking…. It’s big enough to park planes inside of…

My brain is on vacation mode till next week, please explain I’m not following your thoughts.

@AH64D has been talking about sling loading. You just need to build something to load the airplane at points that are already designed to hold the weight of the plane whilst keeping the plane on those points (maybe a spot weld or two). Here check out my engineering plans:

Do Not use the point on the engine, it’s not very strong, however the engine mounts near the firewall should be very ,very strong

How about the lower cradle arms, close to the firewall?  It seems they'll provide the greatest load distribution.

The closer to the firewall or around a welded joint, avoid the middle of straight runs of tubing, to avoid possible bending.  It looks like this has been sitting for awhile, I sense a restoration project is going to save this one.

Hi Clarence.  Thanks for the thoughts.  I agree.  We're hauling it over to a High School for an aviation program (A&P program).

That is one lucky high school!

Looking at the gravity of the situation…

Why the rush to lift it by helicopter?

When it can be dis-assembled, the usual way, for ground transportation…?

the helicopter route has a lot more risk of random occurrence involved…

The flat bed has plenty of experience to go with it…

Looks like a great project for A&P students…  A Mooney ticks all the boxes for GA planes…

Looks like these cylinders may have a cooling challenge…

Oddly…

I can’t find the helicopter lifting a Mooney out of a snowy field.

 

How about a crane doing something similar…. To a Mooney?

This looks like the example of how Not To…  note the crushed aluminum…

I've flown that plane - it's a rental now - got my Mooney ck out in 3535X...

I seem to recall my ovation has non official lettering just forward of the wing root saying it is a lift point.  Why it is on their I have no idea.  Nothing in POH that I can recall.  Airport is closed for remodel so when I am back out there this week will take a pic….or realize my senile mind is making things up.  Seems like there are too many cowboys who just want to lift it, damage be damned.  Not referring to any of you all, just YouTube videos in general.  But it does seem like they caused damaged on right front strap.

The nose jacking point is beside the left tail pipe, a small tube welded to the engine mount frame.

That placard is so silly…. Just wrong.  And it is an official placard. 

When the cowl is off, the Jack point is available as Clarence described…

When the cowl is on… some bozo will put the Jack under the sheet metal hoping for a miracle…

And realize slowly that the Jack point isn’t where the placard is…  too late the sheet metal gets modified…

The O has a really nice engine mount with a Jacking point location…

 

But, for the OP… it’s kind of like the other jacking points…. On the bottom side of things….

The engine mount is a pretty strong location to lift from… just don’t crush it accidentally….
