67 m20F chump Posted April 25, 2019 Report Posted April 25, 2019 I’m trying to replace the nutplates on the inspection covers to the fuel tank. I checked with LASAR and they don’t have a number for what I need. the photo has the flat bottom one and a NAS1473A3 in the middle with the o-ring. I need a part number for the one on the left. It fits the countersink that the small cover has. Thanks
67 m20F chump Posted April 25, 2019 Author Report Posted April 25, 2019 Thanks Dale but that isn’t the one I have on my plane. The one I have has a red cap on it. The one you referred to is the size but it doesn’t have the cap. I have called 2 service centers and the fuel tank guys and haven’t come up with it yet. I have everything cleaned up and I would hate to not replace the ones with broken caps.
67 m20F chump Posted April 25, 2019 Author Report Posted April 25, 2019 I’m going to add a couple more pics. The only other number I came up with is EANA-22-NA1K-02
jaylw314 Posted April 25, 2019 Report Posted April 25, 2019 Is it possible it's just a standard MS21049 countersunk nutplate with a blob of tank sealant on the end?
67 m20F chump Posted April 25, 2019 Author Report Posted April 25, 2019 I don’t know. Makes me wonder what was used on the newer airplanes.
Guest Posted April 25, 2019 Report Posted April 25, 2019 I briefly looked through the IPC and couldn’t find a part number for you. You could contact Mooney for a number then check to see if Monroe aerospace can help. https://catalog.monroeaerospace.com/viewitems/all-categories/nutplates-1 The blob of sealant you see was pushed through the cap when the screw was driven into the hole which was filled with sealant.

carusoam Posted April 26, 2019 Report Posted April 26, 2019 Somebody posted some of these as an answer to a similar question... It appears as if there is a part that will seal the fuel from sealing into the threaded area... Now to find that thread and pic... -a-
67 m20F chump Posted April 29, 2019 Author Report Posted April 29, 2019 Another guy gave me a part number 22NKA38-02. AFMhardware.com has them in stock for under $3.00. 1
