AC 43-13B(Aircraft Inspection, Repair,
and Alteration) is the FAA “Bible” for accepted
practices.
It has
all the rules to live by.
You
probably won’t need the parts for
aluminum aircraft because the kits are so good.
But when you get to the finishing details, you
will need
it.
It contains
info you will need for electrical
systems, hydraulic tubing, safety wiring, etc.
The second book is
the
Standard Aircraft Handbook.
This
little gem has a lot of technical info from drill sizes, to nut and
bolt
identification, to torque specifications.
Mine no longer lays flat.
It is dog-eared
and dirty from constant use.
I
write
notes on things I look up a lot on the inside of the front cover,
saving me time.
