It's up to the A&P to decide if the modification is a major or minor

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
