Hi all,
I am sure that a lot of you have heard of or read some of Ron Wanttaja,'s articles
He writes article and gives talks at EAA functions about safety etc.and does statistical studies
mostly pertaining to homebuilt aircraft. I have known
him for a few years and I wrote to him and ask if he could help with the statistic regarding
RV accidents compared to the rest of the homebuilt community
and this is what he sent me.

homebuilt accident rates. Someone ask how to break the RVs apart from
the rest of the homebuilt accident statistics. I would like to point people
to your article or maybe you could help us out some way with RV accident
statistics. |
I give talks to the local EAA chapters that go further than the articles.

Attached is a page from my presentation where I discuss RV accident causes and
compare them to the overall statistics. The data is based on accidents from
1998 through 2004, inclusive.
"General Pilot Error" is basically mistakes in the stick-and-rudder skills;
"SALA" stands for "Stupidity at Low Altitude," buzzing, flying up box canyons,
etc. In my presentations, I use a red star to call attention to interesting
results, such as the RV's higher rate in what I call 'cross-country' accidents.
The lower rate of pilot error accidents may well be due to the higher general
experience level of RV pilots, as shown by the median pilot hours.
During the subject period the annual fleet accident rate for all homebuilts was
about 0.94% (e.g., almost one out of every 100 homebuilts crashes in a given
year) and the RV fleet accident rate was almost identical (0.90%). In contrast,
the Glasair rate was 1.11%, The overall rate for all N-numbered aircraft was
0.63%, so homebuilts have a rate about 50% higher than the overall fleet.
I'm currently adding 2005 and 2006 data to my database, and will be updating the
graphs accordingly. Don't expect them to change too much, but you never
know....
