That does not mean any procedure has to be actually performed during
cerification.

So they'll certify based on zero evidence? Wow, you just make **** up
as you go, don't you?

Non sequitur.

Certification is based on engineering data and flight testing, not by
going though the ongoing maintenance procedures.

One more time; certification and on going maintenance are two separate
things.

During the certification process, the maker has to GENERATE a maintenance
manual for on going maintenance.

During certification things like the flaps down stall speed is verified.

During on going maintenance the flap hinges are inspected for wear.

Two different things.

Two different things.

The maintenance plan is the basis for what gets inspected when (you
say). The maintenance plan never gets executed (you say), including
little details like part duty cycles and such (you say). This means
that the FAA certifies a pig in a poke.

I never said any of that.

Well, you did, but you're little tiny intellect apparently can't see
around your gigantic ego to realize it.

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'?

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?

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

Irrelevant.

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.

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.

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.

As it amounts to hundreds of pages, I am NOT going to post it.

You will if you think that sort of spew is a useful tactic to protect
your gigantic ego.
