OK, so my right cowl flap is toast. Time to replace. It's cracked, been repaired, cracked some more, was repaired last year again and now that repair is falling apart.

I need the right side, passenger side, exhaust pipe side one. It's Mooney part number 650015-507. If I read my parts manuals correctly, it should be the same part for some of the late '66 Es (serial number 832 on), the '66 Fs and the '67 thru '76 Es and Fs. 

I would have put this in Vintage Mooneys but I know there are some guys with later Mooneys that sometimes have parts and I wanted to hit the biggest audience.

Any help finding this used in very good condition would be awesome. I will check the Mooney price for new just for kicks and also what the MSCs want for used.

As usual, Thanks for the help on this!

If you can't find it you can make your own for probably less than $100 using the old one as a mold and laying up fiberglass by hand.  Owner produced parts provision would apply.  New brackets would be easy to fabricate.

I believe it would not apply. The owner produced parts provision requires you to make the new part so that it conforms to the original type certificate, so a fiberglass one would require an STC. If I made an identical aluminum one from the same gauge and type of aluminum, that would qualify.

beyond the figuring out why it is getting torn up in the first place and fix that, I would be temped to get some sheet alum and a brake and make an owner produced part

It's broken because it is thin aluminum that is 50 years old and has had enough vibration. Making one is always an option, but I'd rather just buy somebody's used one. It seems there is always somebody on here trying to part out a plane, but I guess not right now. I can start calling salvage yards and MSCs, but I thought there might be a fellow Mooneyspacer that I could give my money to and take some stuff off their hands.

Sorry Dave, my bad...

Alan is the star in this miniseries...  He is also a NJMP member...

there is also a guy in the carolinas that has a few trailer loads of Mooney parts.  I have no reference for this...

Hope this is more helpful.

Best regards,

On the later models the cowl flaps are fiberglass with riveted aluminum brackets.  At least that what I recall when I had to pay about $100 for the hinge bracket.

Interesting. I have never seen the fiberglass ones. The Mooney parts catalogs indicate they are all interchangeable. I'd like to see one. Fiberglass probably is a superior material in this application.

oooh if you made some out of carbon fiber that would be worth 10 knots right there.

Only if I leave it unpainted so you can see the carbon fiber and have a wicked looking sticker for my side window. That's how you get the 10 kts!!

Wait, is that sarcasm?  You mean that an alpine sticker won't make my stereo sound better and NOS sticker won't make me go faster?

Guess I am going to have to remove the PROP-JET sticker off my F.

Yes, those original cowling flaps made out of two pieces of aluminum, riveted together are crap.  They are host to corrosion and being fabricated out of thin material love to crack.  Yes, some kevlar & S-glass replacements are long overdue.

FWIW carbon fiber is twice as strong as fiberglass, gram for gram, or half the grams for the same strength.  Do you have something different?

My understanding is the black cloth that we think of as carbon fiber is no the same strength as say like a fuselage that is spun with many cords of carbon fiber.  Looking at the Alum one I would have to think it was a positive and negative die that made them.    A good one and some silicone molding materials, some epoxy and vacuum pump and you could have bling and 10 knot increase

Being a polymers guy...

I would strongly consider carbon fiber cowl flaps.  If I could figure out how to mount them on my plane...

I think somebody covered up my cowl flaps.

Funny O driver, :)
