i have this box on mine, it doesn't sit straight, but it works..

I wonder if an enterprising A&P could take some inconsequential part/piece off an old/unserviceable approved airbox, swap it onto the new "unapproved airbox" and call it a "repair" and meet the letter of the law. Don't they do that with exhausts?

Forgive my obvious ignorance about these things, but I thought that certified airplanes had to have the certificated parts installed? And wouldn't the AME have to use approved parts? I am old school and would love to be able to do what I want, but I am not really interested in an experimental. So I am stuck with doing what the mechanic says is "law" :-(

i replaced my worn out reworked many times certified air box with a uncertified box because i figured what the heck..how many home made airplanes fall out of the sky using said uncertified parts?..

Eric, you are justified in your wanting to do the right thing and use only "certified" parts.
Sometimes the cost of those parts make it hard not to use parts intended for experimental aircraft.

Someone said the approved air box is $1,200 which is what I recall the price to be.
That is why I said if your AME thinks they might be able to repair it, then let him.

Here is a place in Canada that repairs aircraft air boxes:

I know the Canadian reg's are a bit different than the US regarding parts tractability and so on....

There is also a few places in the US that does this work as well...

"i don't need no stinking certified parts"

Thanks for posting that, Wally!
I always wondered what you looked like....

I'm not sure what the rules in Canada but here in the US, the feds do allow for "owner produced parts". Thank Charles for the link: http://150cessna.tripod.com/parts.html

That's perfect Brian! Curious I haven't stumbled on them yet in my quest. I will certainly be contacting them!

The info in the link regarding owner produced parts is interesting, but not relevant in this instance. I certainly don't want to invent, design or manufacture a new airbox for my 150! I just wanted to get a replacement and it seems, like some agree, that the design and build of one has already been accomplished - a la Aircraft Spruce or Wag-Aero. So why can't we legally use that? Bureaucrats! Oh well :-)

You guys are terrific! My first post and the response is overwhelming!
