Today there was another article in "Never Again Online" that is a reassuring read. http://www.aopa.org/pilot/never_again/2007/na0703.html
It makes me appreciate the dual alt electrical system I am installing in my plane even more... Thanks Bob!

Thank you for sharing this find with us. I've posted the
commented article at:
http://www.aeroelectric.com/articles/neveragain/Stress_Changes_Everything.pdf
I would encourage all newcomers to the List to review
the pieces posted at:
http://www.aeroelectric.com/articles/neveragain/
. . . along with Chapter 17 in the 'Connection that
speaks to SYSTEM RELIABILITY and crafting flight
systems that (1) meet your mission needs and (2) not
subject to failures that generate an emergency. To
recap:
# Nuckolls' first law of airplane systems design sez: "Things break"
# The Second: "Systems shall be designed so that when things
break, no immediate hazard is created."
# The third: "Things needed for comfortable termination
of flight require backup or special consideration to insure
operation and availability"
# The forth: "Upgrading the quality, reliability, longevity,
or capability of a part shall be because you're tired of
replacing it or want some new feature, not because it damned
near got you killed."
If these tenants are observed (not difficult to do) then
it makes no difference where you buy your parts, how much money
you spend on them or which parts you select. You're free to
try any selection with the goal of exploring how long it will
last or how well it will perform.

Summarization:
I fly without a low voltage warning light and keep nearly depleted
batteries in my handheld radio. My ships battery probably has one foot in
the grave and another on a banana peel, but I really don't know because of
the lack of a low voltage light and the fact that I've never checked
it. I like to fly with every light blazing whenever possible.
I got very concerned one day when my alternator gave up the ghost and the
airport was busy. I didn't want to divert to a less used airport, and I
didn't want to upset my wife. Fortunately, the handheld worked well
enough to get landing clearance from ATC.

Let's not whack on this guy too hard. First, we should
look to his teachers . . . and the teachers of his teachers.
My own instructors of some 26 years ago were woefully ignorant
of electrical system physics and function. Folks seldom rise
above their teachers. Recall too that only a small
percentage of what is taught is retained. It's probably fair to
assert that the teachers are not getting any better. This
leads us inexorably to the notion that a majority of today's GA
pilots are potential victims of the same or similar situations.
In a segmented, planned activity where everyone is responsible only for
their own part of the plan (and can make your life exceedingly miserable
for transgressions), nobody is responsible for final outcomes.
If this guy's story appeared in the NTSB records as another
smoking hole, it's doubtful that the report would cite all the
ways in which his teachers and other suppliers of goods and services
delivered less than the-best-we-know-how-to-do thus contributing
to his demise.
Given the $time$ that it takes to assemble an OBAM aircraft it's
doubtful that the costs per pound of airplane are much better than
buying a spam can. Where the real return on investment comes is
the fact that folks who seek out and exploit the teachers in
the OBAM venue can ultimately become one with their machine. There's
value that goes far beyond performance and utility when the individual
at the controls UNDERSTANDS the performance and limits of both himself
and all the flight system equipment. Understanding that operates
in an unregulated environment gives us all a real leg-up for taking
responsibility for our own outcomes. Something our
spam-can-flying/government-schooled brothers are not even aware
of.
But be forewarned that anyone who frequents this List will be
hard pressed to garner sympathy for an unhappy outcome if
your own smoking hole comes about because of a lack electrical
system integrity or performance. Unlike the guy who wrote the
AOPA story, YOU have teachers here that DO understand and are
willing to help you understand too.
Recall that the hero of the story in Chapter 17, Martin
Gonzales wrote me some years later to report that deductions
I made concerning his story were dead on . . . he reported
also that an RV kit was on order. Somebody might do Mr.
Shalhoub a good turn by inviting him to join a few of the more
illuminating Lists on matronics.
