Subject: | Re: 601XL wing jig |
We have just got to the stage of using the wing jig. We have a new kit Arrived
7th march 2008) with the pre drilled skins. The jig that was supplied with the
kit was different size to the main spar that was supplied. There fore the holes
did not line up. I contacted Zenith and was told that i did not need to use
the jig because the floor skin was pre drilled. All that was required is to use
the ply templates to set the angle.

Hopefully we can just wait for news instead of the same wild speculation we had
before. Witness reports are conflicting.......

I am a bit concerned with the repeated reports of wings "popping off".
I would like to know the details of the previous failures. Does the
failure occur at the connection point of the removable wings?
Is the failure the bolts themselves, or are the spars failing ? I don't
know it the NTSB reports specify this. Does anyone know?

Two guys, from my chapter, also went down yesterday in an RV10. No
survivors. They were in route from Lebanon TN to Sun-n-fun. Both great
guys. I feel for the families in both instances. My heart goes out to
them. Having known both of them, has perhaps, caused me to reflect on
the topic of speculation after one of these crashes.

Would anyone happen to know whether or not the suggested/recommended/approved modification
was made to the elevator control limits?
I just ordered of all things.... The wing center section and a bunch of other
items less than two hours ago. ( I found out that I was in fact screwed and could
not go any further if you happened to read my post "Am I screwed-Wing Center
Section"
My thoughts and prayers also go out to our fellow aviator who was lost.

Per http://www.nowakfamily.com/airplane.htm, N357DT had a 30 gallon capacity, a center stick and a 26 knot stall speed with flaps extended.
Is it possible to get a 26 knot stall speed out of the standard wing/flap design
without modification?

Hi Sabrina,
I would guess the low stall speed might be indicated rather than
calibrated airspeed and also might be at a lighter than gross
weight. Those sorts of details might not be important to a single
builder, but would be factored in by a manufacturer of many
(certified?) planes.

According to the owner's web site:
Max Load 1320lb
Empty Weight 735lb
http://www.nowakfamily.com/airplane.htm
This do not qualify as an European ultralight. As far as I know, the European and
American version of the XL are structurally the same.
According to the web site, this particular plane appears to have been on sale for
$74,000. I wonder if the plane was sold and the accident happened to the new
owner. My condolences to the family.

The website states that as 26 knots indicated air speed. That is
entirely possible since most air speed indicators read quite a bit less
than calibrated air speed near the stall.

Eye witness reports are notoriously unreliable, especially in a case
like this where the witness may not be familiar with aircraft and is
probably not a trained observer. Lets just wait for the evidence to be
examined before we start speculating on what may have caused the crash.
Eye witnesses in Australia also reported wings falling off in the recent
crash there. It was later reported that the wings were intact and showed
no signs of in-flight breakup when the plane was finally recovered from
the sea floor.

I am not a 601 builder or pilot. My heart goes out to all the 601
guys. I would not take a demo ride in one until what is going on is
understood and remedied.
I am about to start scratch building a 701. I have built tube and rag
in the past.
The 601 crashes have caused me to take another look at the 701. Quite
honestly, I love this airplane and it is probably strong enough to
never have a structural failure BUT nobody could call it rugged. The
thin skins, widely separated ribs, continual talk about oil canning.
I can imagine ia 701 is not difficult to dent. Perhaps the trade off
of structure vs weight has tilted too far toward light weight. Maybe
that is true but just for me. Others would quite rightly feel different.
I would not mind adding a few pounds of toughness to my airplane.

According to the CAW POH for Zodiac 601XL with Rotax 912 as it came on my CD (file
"Zodiac XL POH Sample) together with ZAC manuals and other stuff has really
400lbs less gross weight and indicated stall airspeed 32-26knots, 37-33knots
calibrated.

The 601 and 701 are VERY far apart in design . not even apples and oranges,
more like apples and a Buick.
The 701 has been around for almost 20 yrs (1986 I think) and until recently
when a pilot dug in a wingtip on a low, LOW buzz job , there had never been
a fatality in one. In the homebuilt arena that is almost unheard of. It may
even be the only design that can claim that. Remarkable considering how
many there are and the conditions they are flown in.
Be cautious about adding "toughness" without proper engineering, making
things worse is EASY to do when you change highly loaded, lightweight
structures willy nilly.
Speaking about engineering, you guys gonna keep wringing your hands and
whining or DO something?? LO&SLO John

Because of the proximity to SnF there's little doubt that better information will
come from this accident than the previous ones. And if not better at least
more.
As many have said let's not guess or listen to untrained eye-witnesses. The facts
will come.

Perhaps we will get better information. The publicly available NTSC
reports I have read are not very informative. The link below is very
informative (British Accident Report).

BTW this is the news video of the sun'n fun accident.

I am a bit concerned with the repeated reports of wings "popping off". I would
like to know the details of the previous failures. Does the failure occur at
the connection point of the removable wings?
Is the failure the bolts themselves, or are the spars failing ? I don't know it
the NTSB reports specify this. Does anyone know?

Uh oh...here we go again: "Brownlow said he heard a "pretty loud pop" and
looked up. He said one of the wings of the small plane, he thinks it was the
right one, was flapping alongside the fuselage." My condolences to the pilot's
family, whoever they may be.

I'm still in.
IIRC, Andy Shontz initiated the thread asking listers for a yea or nay on
the analysis. So, I'd hope that Andy would take the lead to make the
analysis happen.
I'm not an aeronautical engineer, and I've never worked in the aerospace
industries. Consequently, I don't know any aeronautical engineers.
However, a former colleague from Los Alamos is the now Dean of Engineering
at Embry-Riddle, Prescott. If Andy is agreeable, I could send him an email
to see if he could recommend someone qualified and available to do the
analysis. Let me know if you're interested, Andy. He would need to know how
much cash was on the table. It would be worth 3 or 4 hundred bucks to me.
