RLCarter Posted August 5, 2022 Report Share Posted August 5, 2022 Not that it would matter…. It’s an M20-C converted to an M20-D (fixed gear)? Check with a Mooney Service Center and see if the parts are available from the factory and if not Mooney should be able to tell you what alloy was used so they can can be fabricated 1 Quote Link to comment Share on other sites More sharing options...
Prior owner Posted August 6, 2022 Report Share Posted August 6, 2022 Call LASAR or another Mooney service center to get the part. It’s an easy one for the factory to make- it comes undrilled. Not a monumental project to replace one on the plane. Are you sure you need both the stiffener and the longeron? Sometimes, it’s just the stiffener (the shorter piece) that is corroded.

I just found some intergranular corrosion on my longeron. Quote Link to comment Share on other sites More sharing options...

Mind showing folks a pic ? Might help others look for it particularly if there are common hot spots. Quote Link to comment Share on other sites More sharing options...
Lionudakis Posted November 3, 2022 Report Share Posted November 3, 2022 Here’s a close up. About a 6” piece. The rest of it looks fine as does the opposite side longeron. Quote Link to comment Share on other sites More sharing options...

Jsno Posted November 3, 2022 Report Share Posted November 3, 2022 Without going out to my plane and verifying, that looks like it is just an aluminum angle extrusion that you can buy from Aircraft Spruce and splice in a piece per AC 43.13. 2024-T3 Quote Link to comment Share on other sites More sharing options...

Alan, That was my plan, finding out what to splice it with was step one. The aft most part of the bad area goes into the horizontal former area and is riveted with both horizontal and vertical rivets. (just forward of the rear most bulkhead) so I’ll be peeling back a little bit of the skin, it doesn’t look to bad to do though 1 Quote Link to comment Share on other sites More sharing options...
