Nukemzzz Posted January 30, 2021 Report Posted January 30, 2021 Putting the cowl back together after installing the EI R1 tach I discovered that the center bar of the avionics stack wouldn’t take a screw. 5 of the 6 nut plates here are broken. Anyone have any tricks or advice for addressing this? I assume we need to call Lasar and get exact replacements, drill and rivet in new ones. But maybe someone has a better idea that gets me back up faster.
chriscalandro Posted January 30, 2021 Report Posted January 30, 2021 Spruce has them. Temporarily you could stick a piece of zip tie in stripped ones and see if they thread. 1
47U Posted January 30, 2021 Report Posted January 30, 2021 Rivnuts. I have a mix - four positions are sheet metal nut plates, but the forward two positions are 10/32 rivnuts. Don’t mix them up when putting the fasteners back in. 2
M20F-1968 Posted January 30, 2021 Report Posted January 30, 2021 Obtain thread sizes and distance and size of the mounting holes from Spruce or other. Drill out and replace. A pneumatic rivet squeezer will likely be helpful if it fits, or a hand squeezer. John Breda 1
Aerodon Posted January 30, 2021 Report Posted January 30, 2021 I know these are quite pricey, but if you are replacing several 1/4 turn fasteners, might be time to upgrade: https://store.skybolt.com/mooney-c724.aspx I also like the 'epoxy in place' nut plates from click bond - especially useful for hard to access places or if you don't have all the tools for nut plates.
