Ron, was that part of the General Pilot Error figure, or did it say?

The figures I posted was from my own analysis, and covered only
non-training
accidents in 172s and 210s from 1998-2004. I didn't find any in-flight
icing
accidents of these aircraft in this period, although several due to not
removing
frost during preflight.

My process was to download the NTSB reports, read the narrative, and come
to my
own conclusion as to the cause. I mostly, but not always, agreed with the
NTSB's probable cause.

Here are the cause categories included in my database:

List only snip

During my analysis, I would assign an "Initiator" (my equivalent of
probable
cause) and check off other categories as secondary/tertiary factors as
appropriate.

The analysis was performed as part of a study of homebuilt accidents,
published
in KITPLANES magazine last year. I included the Cessna 172/210 accidents
as a
control group.


Thanks Ron, sounds like a very educational endeavor. Sorry I missed the
article, sounds like an interesting piece, especially to us Cessna guys.
It's got me thinking I might reframe my question at this point, and start
new post tomorrow.
