Jetdriver Posted January 31, 2022 Report Posted January 31, 2022 Hello all We recently suffered a failure of a landing gear bracket (pn#950099-001) for our 75F and have been unable to source a new one. Trying to get one from Mooney and they can't even tell me when they could ship it. I've tried the usual subjects but does anyone have any recommendations on where I might be able to source one? Being grounded for months is no good. Quote
KSMooniac Posted January 31, 2022 Report Posted January 31, 2022 Post a pic of the bracket or IPC entry and I'll see if I have one. Sent from my LM-V405 using Tapatalk Quote

Jetdriver Posted January 31, 2022 Author Report Posted January 31, 2022 Here's a pic of the failed one. I'm unfamiliar with IPC is that another pn#? Quote
N201MKTurbo Posted January 31, 2022 Report Posted January 31, 2022 I would be more concerned with what broke the bracket than the bracket failing. There is something seriously wrong with your gear system. 4 Quote

There is something seriously wrong with your gear system. Aside from the obvious failure what makes you say that? We did have a suspicion that the gear was rigged too tight but our mechanic couldn't find anything obviously wrong until this happened. Quote

About the only other thing that could cause that is a failed limit switch. I have found a lot of mechanics rig them too tight. I guess they think that if a little tight is good, a lot of tight is better. In most cases it would be better if they just left it alone. Edited January 31, 2022 by N201MKTurbo 1 Quote
EricJ Posted January 31, 2022 Report Posted January 31, 2022 That does look like an odd failure. Something unusual stressed that, so definitely check that the stop switches are working properly among other things. If you can't find the bracket that may be repairable with a doubler. Quote

A64Pilot Posted January 31, 2022 Report Posted January 31, 2022 (edited) I think your going to have to have it made, A&P’s make parts all the time, like wing ribs for example in the repair of a wing Not sure if you got an answer, but IPC is illustrated parts catalogue Edited January 31, 2022 by A64Pilot Quote
Jsno Posted February 1, 2022 Report Posted February 1, 2022 you could get one from a salvage yard. If the holes don't line up you can fill them with a flush rivet and drill new ones. Your inboard seat track is riveted through this. It will be some work but it can be done. Quote
KSMooniac Posted February 1, 2022 Report Posted February 1, 2022 Yowza! That is a surprising failure mode. I agree with the previous comments that your gear system needs a thorough inspection to include limit switches, pre-loads, binding, etc. I have remnants from my salvage J model and I believe that part is intact, going from memory when I removed the gear actuator. If you don't find a better option, I could try to drill it out of my J...it's very likely the same part. I could try to verify in the IPC before starting. It would take a good offer for me to do it, though, as I have a ton on my plate at the moment and not a lot of spare time. PM me if you don't find a quick solution and I'll do what I can to help get you back in the air. As mentioned above, the rivet holes might not line up, but perhaps you can up-size rivets after connecting the actuator. Quote
JoeM Posted February 2, 2022 Report Posted February 2, 2022 paul loewen may have it. https://www.loewensmooneysalvage.com/ He will also be able to help you figure out what caused it to break. Quote

There are a lot of things that wear out over time… But, when things break…. That’s an unusual failure… If they break often, somebody would be here saying how they got it fixed…. A long body broke one of its retract rods, somewhat recently…. Looked like a usual kind of thing to have happen… Somebody had mis rigged the gear… it broke over time…. Anything that breaks gear parts, has a tendency to get followed by a gear up challenge… if you think parts are hard to come by… props and engine OHs to go with that get more expensive… The log books probably have the fingerprints of who did what when… following which procedure… Soooo… When you get the part… make sure it gets set up properly… When something occurs that is unusual… we have the tendency to invite @M20Doc to have a look… he has a memory for these kinds of things… he probably has seen it before… (broken gear bracket) PP thoughts only… -a- Quote
Guest Posted February 2, 2022 Report Posted February 2, 2022 Working on a K model today. It has a doubler installed on the box structure as well. It certainly deserves some investigation as to the failure mode. A decent used part would be a good route for a repair, it is a bit of work though. I’ll snap a picture of the K model tomorrow.

carusoam Posted February 4, 2022 Report Posted February 4, 2022 An invitation for @Jetdriver to stop by for an update from doc above…. More to come later… -a- Quote
