Help!

I'm looking for the reference that IAs use to determine if an
airplane is airworthy despite missing a cowling screw, having
wing tip cracks, or a missing piece of carpeting.

It's called the configuration deviation list, or CDL

Bertie

Is that per airplane model? I've looked through shop manuals and
haven't found a section/doc with that title....

Yes, it's specific to a type. It specifies performance or limitations
down to a missing or damaged bit of airplane. For istance, you might
be able to fly without a small piece of fairing or a panel missing if
you apply a reduced max take off weight. I've never seen one except
on heavies, but the OP asked f there was any kind of document and
that's the only one I know of that meets the description

Bertie

OK.. I was OP..

I'm looking for that sort of reference document for a C172E, and A36,
and a C172N.

I thought there may be a generic FAA doc that specifies some generic
limitation/exceptions/etc.

Dan Mc

Ah, OK. Well the things you are talking about ar largely covered in
arcane manuals like CAM 18, but I have it lying around somewhere and I
think it only refers to structures themselves.

Bertie

Ahh..ok.

I asked the IA I deal with yesterday and he said there were "allowable
deviations" (such as a certain number of missing cowling screws) but
then we got interrupted and I didn't get the reference.

Oh well...

Never saw any such reference for GA - and certainly not for the kind
of junk I fly that was certified by the CAA...

The OP is looking for certainty and it does not exist on the pilots
side of the equation... Let your A&P use his judgement when he signs
the plane off.. Watch him closely and learn... Then you too can amaze
others when you use that rare commodity called, 'common sense'...
