The maintenance manual lists what gets inspected and the maintenance
manual, along with sevreral other things, is part of the required
PAPERWORK package that must be presented during cerification.

You keep leaving out "how often maintenance (including inspections)
must be performed". Is it your claim that the maintenance manual is
merely a 'how to' document and has nothing about 'when to'?

99.99% of the time, yes.

So your claim is that the maintenance manual will say to top off the
engine oil with grade X, explain how to top it off, explain how to
change it, but just say "whenever" when it comes to how frequently the
engine oil level should be looked at and "meh" with regard to how
often to change it?

I'm sorry, but that ought to sound stupid to even your ego.

An individual item in the maintenance manual is normally inspected once
every 12 months. If the aircraft is on a 100 hour inspection schedule,
some things are inspected in the first 100 hours, others in the second
100 hours and so on until everything is inspected within 12 months.

So your claim is that a part that in the maintenance manual is called
out as requiring no inspection will be inspected every 100 hours
anyway?

Yet another childish statement.

Yet another stuck on stupid statement.

Why would something that requires no maintenance be mentioned in a
maintenance manual?

You have again been betrayed by your deficient English skills. I said
"no inspection", not "no maintenance". Can someone whose life is
apparently paper really read this poorly?

Inspections occur AFTER certification when the aircraft is sold to an
owner and is in operation.

Irrelevant.

Highly releveant and a point you keep missing.

Highly relevant to WHAT (that is actually being discussed)? I don't
keep 'missing' it. I don't see why you brought it up in the first
place, since no one had said that they were.

The certification process is a totally separate process that proves
the DESIGN of the aircraft meets the applicable standards for that
type of aircraft and occurs before any aircraft can be sold.

But the maintenance manual, which calls out what must be inspected and
maintained when is a required input to certification and used (by your
own claim) to determine what to inspect.

During routine, on going maintenance, after certification is complete,
and the aircraft is sold to someone.

Which part of "so what?" is it that is leaving you confused?

The design is certified by a combination of one time engineering
calculations and actual testing (assuming no failures during the
process).

And by the presence of a document that controls inspections.

Nope.

Yep. You've said so yourself.

During the certification process separarte TESTING documents are used
to perform TESTING, not routine maintenance.

Who gives a ****? You're still stuck on stupid and apparently unable
to parse simple declarative English sentences.

Before you say something else blazingly stupid, you should read
ALL of Part 25 14 CFR and see what the actual requirements are for
the certification process.

Before you say something else blazingly stupid and irrelevant, YOU
SHOULD TRY READING WHAT OTHER PEOPLE ACTUALLY WRITE. For example, you
keep blithering on about how normal inspections aren't conducted
during certification, as if someone had said they were. The only
person saying that is you.

You are the one going on and on about inspections during certification,
not me, you lying sack.

Hogwash. I've done no such thing. Stop listening to the little
voices in your head and read what people actually write. Let me see
if I can make what I'm saying so simple that even your gigantic ego
can figure it out:

1) The maintenance manual, which must be complete at certification,
determines what is inspected and tested during operation. YOU have
said this, even though you've made the remarkably stupid statement
that there is nothing in the maintenance documents about how
frequently anything should be done.

2) Given 1), above, quite obviously there is a link between
'certification' and 'testing during operational use'. Well, there is
unless you think they just burn the maintenance manual once
certification is complete.

Get it now?
