Metal Repair

[aerobat95]

Hey guys in this pic you can see where there is some cracked metal near the exhaust.  Its where the exhaust tube exits the cowling area.  Is this repairable?  If not is this a part that can be purchased?  You can see where it was stop drilled but if I can fix it I would prefer that option.

Ray, you might call LASAR and see if they have a replacement in inventory.  If not, you could likely patch it with a doubler on the inside, or perhaps find a homebuilder/fabricator and get it duplicated from raw sheet stock.

I don't believe a doubler will hold for very long. Either LASAR or a local refab are preferred. Have you determined what's causing the cracks?

[aerobat95]

No I am not sure what caused the cracks....they were there when I got the plane.  You can see they were stop drilled and there hasnt been any further cracking.  How would I find what part that is?  Also what do you think it would cost to have a local refab make the part?

Keep an eye on the exhaust hanger.  Mine wore a hole in the firewall.  Caused some tension unitl we worked out the solution.

Get some good local PMA approved ;-) sheet metal homebuilder to look at it, and it will be only a fraction of one AMU, I'm sure.

[aerobat95]

How did it wear a hole in the firewall?  what did you do to correct it?

[aerobat95]

I will have to see if I can find a local PMA approved sheet metal homebuilder :-) Anyone know anybody in San Antonio that can do that sort of work?

Ray,

 

That is really out of shape too.  Aside from the crack, it is all bent by the screws.  My m20c had some doublers with many rivets and stop drills too.  It seems like the part is susceptible to erosion also.  Fortunately it is not at eyeball level, and it is not a super tight spot either....I vote for A&P fix it up, while searching for mooney replacement.

 

That west coast chopper guru would knock this stuff out in 15 minutes on TV.

 

Best regards,

with the amount of damage there you should go ahead and see about replacing that. I could come down to take a look. Where do you have it parked? I am not doing anything this Sat or Sun in the morning and I am cheap. Coffee in the morning is all I need. We can take a look, see what needs to be replaced then find the part. Dugosh might have somthing that works or we can call Don. Send me an email at rheitzman@amsafe.com and we can set date / time. I need to keep the rust off my tools and dust off my A&P license.

 If it were me, I'd be looking for a salvaged Mooney ( ie Wentworth, etc) and try to buy that piece. Paint it and call it good.....

I am going to be getting a replacement on Monday.  Thanks for all the advice.

I have the spring type exhaust hangers and one broke and was rubbing against the fire wall and wore a hole in it.  AP put a patch over it.
