Hey folks,
1964 M20E
I’ve had to take off my cowling a number of times lately as I’m having some avionics work done. The screws holding in each side of the access panels and the small center strip seem to be randomly sized. When I put the panels back on, I’m having to try the different screws when the one I choose doesn’t fit. It looks like I have two different sizes (see picture). I took them to a hardware store and they measure M5 and M4 but I’m not sure if that matters. The larger of the two doesn’t typically fit so I’d like to order more of the smaller ones. The parts catalog I received with the plane shows the cowling for 1965 and a screw - AN526-1032R8. Side note: The parts catalog says serial numbers 470-831 is 1965. Mine is #476 but my registration indicates 1964. I think it was completed in November. I assume this catalog is correct for me.
What page would I find the access panels on? It’s not the cowling I need screws for but the access panels (pictured). Is the AN526-1032R8 the correct size for these? I know these holes get worn and different sizes may fit but I’m looking for the original screw size.
Thanks,
~ Dan
