Fusco Posted January 28, 2023 Report Posted January 28, 2023 I am new to the Mooney world and airplane ownership in general and recently bought a m20c and noticed it did not have any tie down rings on the wings. I kind of assumed that maybe it just doesn't have them but I was told it certainly is supposed to. Before I go and buy a pair that will certainly not fit with my luck, does anyone know where to get them? Quote

I think they are simple eye bolts, I bought the LASAR ones myself as I think they are good jack points. POH I think says remove them before flight I believe, and that may be while yours are gone. But I see it being a good sign, I see it saying airplane was hangared, not tied down. I’m a bad guy, I don’t remove mine or I’d lose the things. 1 Quote

I don't think I'd remove them before every flight, I would certainly lose them as well! Quote

Rjfanjet Posted January 28, 2023 Report Posted January 28, 2023 Another vote for the Lasar jack points/tie downs. Quote
Guest Posted January 29, 2023 Report Posted January 29, 2023 Meyers jacks flatten the LASAR tie down ring. Quote
PT20J Posted January 29, 2023 Report Posted January 29, 2023 (edited) Check, but I think it's a 5/16-18 thread. You can buy a generic part called a lifting shoulder eyebolt (the lifting part is important to make sure it is strong enough, the shoulder is what causes it to seat against the wing skin when tightened). Edited January 29, 2023 by PT20J Corrected thread size: Was 15/16-18. should be 5/16-18 1 1 Quote
0TreeLemur Posted January 29, 2023 Report Posted January 29, 2023 I just removed those from our J to install the Lasar jack points. I've got two I'll send you. The thread is 5/16" x 18. PM me if you want them. 1 Quote

That is one BIG bolt for an airplane. 1 Quote

Somehow the threads get damaged over time and are re-threaded to 3/8-18 or eyes are just left out. Quote
podair Posted January 31, 2023 Report Posted January 31, 2023 (edited) my situation exactly, the original threads are damaged , the original eyes drop out, and I want to fit the Lasar ones. A repair using a helicoil repair kit has been suggested . I am based in Europe so need to source the correct helicoil kit. Should I look for 5/16-18 or 3/8-18 as suggested above?

Many years ago, I taxied out of a tiedown with a chain still attached. Pop. Pulls the ring right out. I took it to my mechanic and he laughed at me and handed me a helicoil kit. I was able to use the original tiedown eye afterwards. Quote

N201MKTurbo Posted January 31, 2023 Report Posted January 31, 2023 My old Mooney had a stripped out tie down. I just got an eyebolt with longer threads and put a nut in the wing. The hole is right next to a structural member so I had to grind the side of the nut away. This made it so I didn’t need a wrench on it. The only downside was I had to take an inspection plate off every time I wanted to jack the plane. Quote

carusoam Posted February 1, 2023 Report Posted February 1, 2023 Go with the Lasar deal… they have the Jack point in place… they look aerodynamic they are shiny… When they get squashed by the jack… it’s only a little squashed…. For the tail parts… make sure you know what year you have… the two hole centers changed dimension around 1965 or so… (part looks like a handle) Lasar or any MSC can sell the tie down rings… my M20C had funky rings that were oriented with the airflow.. thinner in the direction of flow compared to a normal eyebolt… PP thoughts only, -a- Quote
