Exhaust Clamp Snapped in Half

[TheAv8r]

The clamp that holds the tailpipe on my 1965 Mooney M20E has snapped clean through the metal. Looking at the parts catalog, this is part 630089-000 (#16 in this diagram). Not having any luck searching around online, I've emailed LASAR but figured I'd ask here if anyone has one? Worst case scenario I can see if a welder can repair it, but I'm not optimistic.

@TheAv8r Texas Air Salvage may have one that will work as a replacement:

This is obviously not a consumable part, so I doubt that anyone will have them "in stock". I'd try a salvage yard such as Texas Air Salvage.  You can find them and others on the web.  Ask your AP/IA to inspect it.  This should fall under pilot/owner supplied part or the new "Vintage Aircraft pre-1980" parts FAA interpretation I would think.  I would not try to weld this back together.  There will be a "heat affected zone" and unless you want to take it to a weld shop that can then heat treat it, I would expect it to fail due to these stresses and the vibration this part sees.  Best of Luck. -mark

I’d just take it to a welder and have them make a replacement. My A&P has folks he uses for that kind of stuff; you might ask yours for a recommendation.

Thanks, that Texas Air one has 2 bolts on either side, mine is a continuous clamp all the way around with 1 bolt that goes through to hold tension against the tailpipe. I agree a welder making a replacement is the best option, I'll run by a shop and see what they can do.

I was thinking if you unbolt the salvage one from the strap, you have a bolt on replacement…

just a thought…

Owner Produced Part. 
 

A good welder fabricator can whoop one out in no time. I wouldn’t try to repair it, I would just make a new one. It’s made out of 304 stainless. Use the busted one as a pattern.

You know the FAA inspectors stay awake at night thinking of ways to catch people who make exhaust brackets……

The folks that just did my annual replaced that assembly (rubber and all) with a new part.  I believe they got it from Mooney in a few days.  I can verify their source and cost if you’re interested.  It wasn’t very expensive.

Take it to a metal shop

Show them what you want them to make out of similar material and do it as an Owner Produced Part.

Simple and easy.

YOU sign the log book saying you had the part made to your design and the A&P signs it off as installed same 

Simple easy and legal

^^^^This is the way… Find a machine shop. Take them the old part.  No need to tell them it’s for an aircraft.

In Fl if they get suspicious we tell them it’s for an airboat, sometimes they grin.

One guy didn’t understand that he had no liability, I explained to him the the FAA actively encourages Certificated mechanics to for example have a professional welder repair an exhaust as opposed to them trying themselves. An A&P isn’t expected to be an expert in all disciplines and in one they aren’t should seek out an expert.

Very few A&P’s can weld very well, almost none could be considered Journeymen welders.

A non certificated person is allowed to work under their supervision.

The welder has no liability because it’s the Certificated mechanic that determines airworthiness and signs the repair off.

Some understand, some just don’t want to have anything to do with airplanes period.

What I’m saying is any A&P should make that part without issue.

I don’t really understand the line that requires an Owner Produced Part, for instance if you smack a pole with a wing and I’m repairing it, no one raises an eyebrow if I make the skins and even wing ribs, stringers whatever. That’s been done forever.

So where is the line that requires an owner to produce the part?
