Need a name/PN

GAdams · #1 07-05-23, 10:38 PM

Hello All,
On the top of the engine cowl just forward of the windscreen is a panel which is held down by several cam locks which permits access to the back of the instrument panel from outside the airplane. On my 337D the panel has a gasket which keeps water from seeping inside. I've spent the last two hours looking in the IPC and not knowing what that is called, I need the name of that part or the page/illustration number in the IPC. Or if you know the part number or where to get the gasket it would be very helpful. Thank you

These pages are from the G model IPC, but maybe it’s helpful?

Also, search the board for “avionics access”, there’s a couple threads about sealing up those access panels with RTV in the cups and weatherstripping on the panels.

We often just tape it with clear duct tape. I have known guys who have ruined g500's before they started taping it. Works great and keeps it dry.

The part number is S2130-1 and is the rubber seal that is glued into the channel that runs around the perimeter of the avionics bay access doors. Textron has over seven hundred feet in stock.

I replaced them on my plane about two years ago. At the same time, I replaced some of the capped camlock receptacles that had rusted holes in the bottom that had been allowing water to drip into the avionics bay behind the instrument panel. Problem solved.

I think the seal p/n is different between the planes with one avionics bay cover and those with two

In a crisis, used some good quality weatherstripping from hardware store and not a drip since. Interested in sourcing the cam lock screws due to rust. Open to any information on that. My previous search unsuccessful.

The recepticals for the camlocks on the access bay panels are found here:

https://www.clarendonsf.com/products...ers/26r16-1fgv

https://www.boeingdistribution.com/p...6R16-1/26R16-1

I bought some a few years ago, and can't remember exactly who I bought them from.
They have the same p/n as the cessna parts manual 26R16-1, and I would not/did not hesitate to install them on my aircraft.
the camlock fasteners are different, and can be found at Aircraft spruce:
27S3-3
27S3-5
Depth / length are the deciding factor.
As far as the gasket, if you are looking for a quick, non expensive, water proof seal.............
Go to your favorite pool store, and in the "aviation dept", find a tube of Pool and Spa lube. I use a finger and spread down into the panel spaces, a fine film on the gasket, and around the camlocks themselves. It is sticky, but cleans up quickly with a rag in mineral spirits. I have never had a water issue on mine.
Regards,
Randy

OH, also.... Hi Capt Erwin. If you get down Tucson way, give me a shout.

It's great to hear from you Randy! I'd love to drop in and see you sometime.

I think I got a lot of true milspec stainless hardware from

If I DO get shot down, at least the wreckage will look really cool.
