I thought that was the way it is supposed to work too, as reading the
regs seems to overtly state this. But in actual practice the A&P is
now being basically required to seek permission from above whether he
can declare something to be minor or not... that he is expected to
assume everything is major unless the FSDO grants him permission to
declare it minor after they review the details themselves.


If they bounced back 337's that were minor alterations, it would help
everyone out.

I thought they were supposed to do exactly just that too -- to
"decline" the 337 with a note stating that the job is minor and to log
it as such. But that's not what's been happening in real life.


Good luck

Thanks, I'll probably need it, but my IA did say that the 337 for the
PSE intercom should slide right thru the bureaucracy like greased
butter since a TSO'd part is already an approved part and its
installation manual also constitutes "approved data" for the 337

It is the way it works. There is no requirement for an A&P to seek
approval/permission for any modification if in his/her estimation it is
minor in nature. As an A&P I'll sign off anything I believe is a minor
alteration without anybodies approval.
If it's a major alteration, then a FSDO approval is necessary and an IA
needs to validate the alteration was done in accordance with the data
approved.

If they bounced back 337's that were minor alterations, it would help
everyone out.

Just because something is TSO'd doesn't mean that it can be installed
every aircraft. TSO's is nothing more than paperwork way to try to
generate quality in a product.
It's a label like the "UL" label on kitchen appliances.
I could probably get a window AC unit TSO'd but it doesn't mean that you
can install it in your airplane. It means that it passes what ever TSO
standard that it was manufactured to.


Take a look at part 43 appendix A, it's pretty interesting.


Cheers!

You seem to be determined to engender an FAA paperwork blizzard. If so,
please go for it and don't bother with these newsgroups. If you have a
reasonable A&P who installs it and a reasonable IA who does your annuals,
the FSDO will never have a clue as to what is going on.

On the other hand, you seem to want to tweak the FSDOs nose and get them
into the "approval" process where it is not necessary. Your call, and your
airplane.

Most of us out in the unwashed backwater airports don't give a good god damn
about the FSDO, just about keeping our airplanes airworthy to the highest
standards. Again, your call, and don't give me the crap about the FSDO
pulling an inspection on you out of the blue.

Just hope they don't go tell you the intercom must also be STC'ed for
your aircraft before they allow it or to go hire a DER to create
approved data or to take it to one of those big city multi-million
dollar avionics shops to get installed. Up here in northern Texas, an
intercom installation is also considered a major alteration. My AP
says they claim it modifies the basic design of the comm radio system.
Must be a Texas thing.

OTOH, the Air Gizmo dock for a Garmin x96 is deemed a minor alteration
in this region and the GPS and dock can be installed for VFR-only
under reference of AC-20-138a with only a logbook entry, even when
hooked up to the ship's power and an external antenna mounted. Go
figure.
