N201MKTurbo

And it was drawn by a Mooney!

Your best bet is to send a letter to the PO Box. You could contact the local airports around Muskegon.

I finally got tired of sanding and painted my headliner. It was in 9 pieces with some major holes. The plastic was vert brittle. It had the structural integrity of a saltine cracker. I reassembled all the parts with fiberglass and epoxy on the back side. Recreated all the missing parts with fiberglass. Sanded, painted, built it up with more fiberglass until it looked good. It is very robust and about as flexible as the original plastic.

If you replace them, you will traumatize the fiberglass and paint. Chasing the threads will get it working without screwing up the appearance of the cowl.

This is what I have:

There are floating and fixed nut plates. Just look at them and you can tell. You can also chase the threads with a tap.

That gearbox should be full of grease, and the grease should have MDS which will make it black.

I will try to get out to the hangar and take a look at what I have.

I have an annunciator panel in my junk pile. Send me a pic and/or part number and I will see if it will work for you.

I think the only option is for somebody to develop a PMA replacement. The world is full of gear motors.

I was looking at the Globe Motors Alabama facility. The local news from last week says that they are laying off 1/2 of the work force. I suspect that includes the folks that rebuild the motors. https://www.montgomeryadvertiser.com/story/news/local/alabama/2025/06/17/globe-motors-layoffs-coming-to-alabama-manufacturing-plant-in-dothan/84190402007/

Ok, might as well buy a new engine well you are at it.

I think it is an NAS1304 close tolerance high sheer bolt.

I will never understand why you don’t just send the prop for overhaul, and buy a new spinner bulkhead.

There is a guy at the airport with a mill. I could modify the bolt in about 10 minutes. Warner Propellor will replate hardware for $100 a batch. So, I can make you one for about $120. I could make 100 for about $250.

I threw my shock away in 1989.

They now say there will be a usable ramp this Friday.

Where is it broken? A pic would be good. Can it be repaired? Can you make one?

Air Power says they have 2 in stock. And they are the cheapest. https://www.airpowerinc.com/632062-2a1 Oops, Google screwed me, wrong PN.

I have an old Bendix Pioneer 2” vacuum gauge I bought on EBay for $10. It is my gold standard for checking vacuum. It is dead on accurate. I checked it against a mercury column at the instrument shop.

I’ve always heard the 727 was a fun plane to fly. It is pretty much a 737 with another engine thrown in for good measure. When I first started flying Mooneys, I was based at an old private airport (01V) that was the retired airline pilots lounge. The couch in the office always had a few. One old guy told a story about him being on a check ride with the feds in a 727. The FAA guy asked him to do a steep turn in some flap, slat, speed brake configuration. The fed expected him to say that was a bad idea. He knew what it would do, so he did it and snap rolled the plane. He said he looked over at the FAA man and said “Is that what you were looking for”

Cowling kissing engine, or something in the cowling resonating with the low power.

Agree completely. Most Cessna’s, especially the twins, the flaps are speed brakes. But we are talking about Mooneys. They are a little different.

As long as we don’t break anything, to each his own. I do the gear first because it has a faster speed. The gear drag slows me to the flap speed. I figure the gear is for drag and the flaps are for slow.
