I've got a suggestion for all ZBAG'rs!
Focus your efforts on Cirrus -- as this brand of aircraft has contributed to 78
deaths in 110 accidents since 4-10-04!
Then, take a look at Cessna, Beech, Piper, etc...
During the same time period, Zenith had 24 deaths in 46 accidents.
All aircraft have the tendency to fall out of the air, as if you didn't know.
Pilots, passengers, etc. are encountering chance every time a plane takes to the
air.
Now, please drop the matter as you know not how much unnecessary damage you are
creating!

How many Cirrus, Cessna, Beech, Piper, and so on aircraft are flying, and
how many Zodiacs?

Sure. That doesn't mean we have to ignore problems specific to the type if
they exist - and the accident rates say they do.

That doesn't mean we have no obligation to minimize risks and fix problems.

I'm not going to just wash my hands of the Zodiac's safety. That would be
the ultimate in irresponsibility to myself, my loved ones, and aviation in
general.
You can forget about improving aviation safety if you want to. I'll not so
politely ignore demands that I do so.
Even if, as your message shows, you don't give a fuzzy rat's posterior about
being safe, I do.

Hi Mack,
That is an interesting comparison of apples to oranges.
To be a reasonable accident comparison it needs to consider how much
flying was done in each of the airplane makes listed. Perhaps you
have the best numbers. I would guess Cirrus has 100 times as many
flight hours as Zenith and Cessna 1000 or 10,000 times as
many. Remember Cessna accounts for the top three models of light
planes shipped in history - the 172, 182, and 150/152. Also, most
Cessnas and Pipers are old and worn pretty thin.
I agree with you completely that all types of planes have fatal
accidents. It is only a rare exception where a given make and model
have a much higher rate of accidents than other ones. There is also
the issue of what kind of accident happens. When a freshly minted
Sport Pilot takes off in IMC you can't really blame the plane for the
outcome. On the other hand, when a plane has the wings come off in
level flight in the traffic pattern you have to wonder what
happened. When a plane as unpopular as the Zodiac XL (probably less
than 1000 flying before the problems surfaced - a lot less now) has 5
or 10 wing separations in two years you really need to wonder what is
behind the failures.
I really wish we could stop blaming ZBAG for the problems in the
Zodiac XL. They didn't create the problems and blaming them only
inflames the community.
I know you and many other Zenith people wish this whole problem would
just go away. Unfortunately, it is going to take some design changes
for that to happen.

I have been monitoring the matronics posts on the 601XL for the last six mo
nths for obvious reasons (we have one with 240 hours on it now). I am stru
ck by the increasing intensity of the "discussion", the willingness of some
to accept a one-size-fits-all NTSB explanation (and one with very question
able statements), those who are clearly exceeding the design specs and have
other very bad and potentially fatal habits, and those who have not adapte
d their flying techniques to the airplane.
Accepting a NTSB explanation at face value, or thinking that whatever they
say = "safety", is a not fully productive approach. Flutter may be an ex
isting problem -- but that is not the whole story.
Those of you who freely admit to exceeding design specs may yet rip the win
gs off your airplanes. Someone may then call it a flutter problem when, in
reality, it is a pilot problem. That is not a Zenith problem, but you wil
l make it look like one.
The 601XL is pitch sensitive. It takes about 10 seconds to figure that out
-- sort of the difference between a Porsche and a truck. This is not a C-1
72 so don't go whapping the stick around like it is. That alone can lead t
o structural problems. Do not try and do silly unachievable things like "c
ountering turbulence" with rapid control inputs, as someone alluded to -- i

Hi Guys,
I'm sure this has been mentioned before but...
I have installed my elevator cables and there seems to be a difference in
tension between normal and fully up elevator. If this is normal, when do I
check the tension, normal or fully up?

Hi Peter,
Keep in mind the "Up" cable must support the weight of the
elevator. I am not sure how this changes with different elevator
positions, but I suspect the forces on the two elevator cables will
always be different from each other.

Just a thought. I just closed my arm rest and thought, how will I make
cable adjustment. When I do need to adjust the cables I will move the
turnbuckles so I can get to them using the door that I have added (like the 601xl,
I think) just aft of the rear spar on the bottom. This will require adding
a short section of cable to the bracket and reducing the cables length.

Jerry,
I have moved the turnbuckles so they are accessible from the rear access
door. They are much easier to adjust. I tried holding the elevator in the up
position and the elevator cable is still tight. Is there some asymmetry in
the cable geometry?
Cheers
