....The Zodiac is a nice design, and its unfortunate that there have been some dumb pilots killing themselves....
The "dumb pilots killing themselves" argument doesn't hold water, unless you believe that Zodiac pilots are, on average, dumber or more reckless then pilots flying similar aircraft.
The fact remains that Zodiacs are experiencing a higher rate of fatal accidents when compared to similar aircraft. Let me illustrate:
I ran some quick numbers regarding fleet size, accidents, and fatal accidents for the 601XL and two planes with similar performance, the evektor sportser and the Remos. These accidents are SOLELY for Factory built aircraft, not ExAB.
The Remos has a fleet size of 118 aircraft, have had 7 accidents, with 1 being fatal (remember the crash at sebring when the demo pilot didn't secure the folding wing?).
The Evektor sportster has a fleet size of 95 aircraft, with 14 accidents, but only one being fatal.
The 601XL has a fleet size of 71 with 5 accidents, of which 3 were fatal. One was for fuel exhaustion. The other two were in flight wing failures "for undetermined reasons". Why are we not hearing about such in flight wing failures "for undetermined reasons" with other SLSAs?
If you compare the Zodiac 601XL to other homebuilts, the results are even more dramatic. One method I like to use is to take the total number of fatal accidents an aircraft has and divide that by the total number of accidents. The result is the percentage of fatal accidents. As a general rule, the fatal accident rate is directly correlated to the stall and cruise speed, hence the adage "speed kills". Thus, a super fast Lancair should have a higher fatality to accident rate than a Pietenpol. As a baseline, a Cessna 172 has a fatality rate of about 14%. The Cirrus line has a fatality rate of about 42%.
Here are the results of some popular homebuilts.
All homebuilts for the past 20 years: 28%
All RVs: 31%
RV 6 (most popular kit ever): 27%
RV 4: 36%
RV 9: 0% (yep, 482 flying and they haven't had a single fatality)
All Lancair homebuilts: 46%
Lancair Legacy 54%
Pietenpol: 16%
kitfox 13%
Sonex 12%
Zenith STOL 701 6%
Velocity: 26%
Glasair: 36%
Zenith 601XL 47% (it goes up to 50% if you include the crash from Thursday)
Why is a non-aerbatic LSA, with a full flaps stall speed listed at 38kts, and a cruise speed reported between 105-115kts (depending on engine) have a higher fatality to accident ratio than every plane or group of planes that I have listed, except the 240kt cruise, 60kt stall Lancair Legacy? It does not make any sense.
