AC 43.13, welding and a hip-check

Background: I have a wing strut with a bend in it and it may also be
cracked.
Looking thru AC43.13 at various welding options raises some questions:

Before you even comtemplate doing ANY strut repairs like these, get a
copy of the repair limitations out of the structural repair manual for
the aircraft. Many of the SRM's state that there are no repairs
allowed on the struts. Others allow repairs only if the damage is
within certain limts and/or locations.

When you make a repair like this without the guidence of the SRM, you
now become a permanent test pilot/structural engineer/ stress analyst.
With certain structural items, it's far better to be conservative than
not. A strut failure in flight is about as close to an absolute
guaranteed fatality as you can get.

BTW, what are you working on?
