Looking for seat track pins

[WAFI]

Not sure what the official name it is but I'm looking for a set of seat track pins that keep the seats from coming out. Does anyone know the size and length I need? I don't trust cotter pins...

Some people use Clevis pins, others use bolts with a lock nut. I don't know the size off hand. The Clevis pin with a hitch pin clip is easier to work with in my opinion.

From the IPC, item #26 is supposed to be AN380-5-3, cotter pin 5/32” diameter 3/4” long.  Later models used pair of bushings, a machine screw and nut

[PT20J]

The Mooney solution of a screw, two bushings and a locknut was too much hardware for me. I replaced them with a screw, two threaded standoffs and a lockwasher. #8 machine screw if I recall correctly. Works great, and easy to remove and install with just a screwdriver.

[WAFI]

So, 5/32” diameter one of these should do the trick.

I have hitch pins and occasionally they come out, maybe we are hitting them with our feet?

The cotter pins work, the seat won’t go too far with them in

I don’t think I have ever seen a 5/32 quick release pin but if anybody finds a source I’m interested, like to try that myself 

I thought I could find a 5/32 safety pin but no luck, just cotter and hitch pins so far

I have the equivalent of the Cessna stop pins, like this:

only with safety pins instead of cotter pins, so they're easy to pop in and out.   Makes removing/replacing the seats a breeze.

The bracket goes over the seat rail and stops the seat.

A web search on "Cessna seat stop" brings up a few options, but I think they come from McFarlane:

The safety pin is just the usual that you can get at just about any hardware store or in the aviation aisle at Lowes or Home Despot.    You can get the clevis pins there, too, and the "bracket" is just a little piece of sheet metal that can be fabricated pretty easily.   If somebody wanted to put their own together it wouldn't be very difficult.

I’d say they are a good length, but shipping starting at $40 for ground for four pins is nuts.

[hammdo]

I agree! Maybe a bulk order would be a better start...

Four 1” pins about $5 ea, shipping about $10, total $34.

I didn’t go measure, but gut says 1” will be fine.

Now to hope the holes aren’t wallowed out, because I didn’t measure that either.

Oh, being a sail shop they should be 316 SS not 304 SS, should bees don’t make honey though 

Read the description says 18-8 which is 304. Fine cause I don’t sail the Mooney in salt

Wow, y’all like to spend money.  These are about 50 cents each at your local hardware store.  You need 4.

It's not called AMUs for nothing ;o)

I have them in my airplane, occasionally they come out. You figure that out when the seat goes too far and you have to put it back in the tracks, no big deal, but annoying as everyone has to get out etc. I’ve taken to pushing them in all the way and that has seemed to help. I do like the quick release feature though and why I’m going to give the quick release pins a go, too bad the one with the button isn’t available.

I also draw a line with a sharpie on the seat track prior to removing them, makes finding the hole a lot easier on reinstallation.

The pins came in before the hurricane and seem to work well, they fit perfectly.

‘But they came in a bag marked Mc Master Carr, so maybe they could have been bought direct for less money.

Curious why you don’t trust cotter pins . Very cheap and do the job .

Pain to R&R and if you ever had to remove a seat while away from home you may not have the tools to do so.

‘Now if we could make the back seat quickly removable

Simple, I sheered one off trying to adjust my seat in a Piper back in flight school. Try flying with you seat not locked into the track, it makes for a fun time.

I probably couldn't do it again if I tried but its always in the back of my mine.

Looks like they are $2.28 each on the McMaster Carr website with about $8.50 shipping

I used these in the past and when I had it in for an annual at a MSC they replaced them with cotter pins. Is there anywhere it is specified what can be used?

I would love quick removals, especially when I need to get the co-pilot’s seat out for that special someone who takes up more real estate.
