Don't forget the legal issues. I'd wager that's a bigger cost
for
many, many things airplane. Look at the Facet fuel pumps used all
over. Exactly the same as the one you get at NAPA, but it has a
safety-wire hole drilled in it, and serious legal ramifications if it
fails.

Many years ago, the plastic upper door cam lock on the rear door of my
Piper Lance broke. It differs from the one on the front door only that the
cam is reversed. The cost for the front part was approximately $2.00; for
the rear was $70.00.

Go figure.
