Folks,

Help me understand the most basic alteration/modification/addition. This
"simple" category. Some conclude this device fits that category.

If my IA determines that screwing a bit of plastic onto the instrument
panel (using the existing mounting rails with approved hardware)
constitutes nothing more than a minor alteration, can he simply make a
logbook entry and sign it off? What other paperwork must he execute, if any?

Once done, what happens wan an FAA critter with an attitude problem at
some remote airport where I am not based comes along, peeps in the
window and says "where is your paperwork for this thing"? I don't carry
my logbooks. What do the regs say I have to do (produce) right there and
then? Providing I follow the rules (which you just told me), what can
the FAA person do according to the regs?

Where possible, please point me to the chapter and verse. Where
impossible, please let me know why you reached a conclusion where the
regs are nonexistent or vague.

Thanks,
Mike
