REFLECTOR: AN washers

[KeithHallsten]

Why would you want a bite in the part at the edge of a washer?  Sounds like
a stress-riser to me!  Interestingly, I looked in AC 43.13-1B, and the
"Washers" section says nothing on the subject.  However, I was always taught
to put the smooth rounded edge against the part, and leave the sharp edge
out in the breeze.
