John, too bad for me that the fly in isn't a week or two later. N6PJ
should be ready to go shortly. Yesterday, I was going to reinstall
the wheels for the first time on the new axles but I simply could not
get the bearings to slide all the way on. Apparently the axle is
slightly oversize. I am going to have to work it down with sand paper.
Same problem, both sides.
As far as the exhaust system is concerned, mine is very
"experimental" and until we hear it, there are no guarantees. All
you have is my opinion that it will do the job. I would love to bolt
it on a running 13B just to know for sure. Two things about it can be
said: 1) it will never burn out and 2), it will fit inside the engine
mount I build.
I don't know if I can attend Plainwell or not due to prior
commitments. Since I could not fly, I was not planning on attending
and did book some appointments on both Sat and Sun. I am trying to get
out of the Saturday ones today. See you, maybe-----Jerry

Revisiting the wing root fuselage connection.
My plan set, #1137, did not clearly state that plywood doublers
were to be installed at the root of the main spar. In an amateur built
aircraft such a detail being left rule-of-thumb is inexcusable. As I
understand it Steve did not draw the plans, a fellow he gave flight lessons
to did them.
Last night I preliminarily evaluated the spar material without
the plywood doublers. It is very weak loaded perpendicular to the grain.
When I added plywood to the sides of another test sample I was unable to
break the sample in my simple loading device. I will prepare better
samples and test them in a manner that I can put numbers to the forces
required to fracture the samples. But for now bottom line. Since so many
plan sets went out without clearly calling out for the plywood. I recommend
that if you are not sure the plywood is in there cut an inspection hole in
the bottom surface of the wing and have a look.
HAD I NOT BEEN A MEMBER OF THIS LIST I WOULD NEVER HAD CAUGHT
MY MISTAKE AND THAT MISTAKE MOST LIKELY WOULD HAVE KILLED ME AND ANY
UNFORTUNATE SOUL WHO HAD PUT THERE LIFE IN MY HANDS BY ACCEPTING A RIDE

TESTS AND RESEARCH
The inboard 15-inches of the right wing spar was sent to the
United States
Department of Agriculture (USDA) Forest Product Laboratory,
Madison,
Wisconsin, for examination.
According to an examination report, provided by USDA Forest
Product
Laboratory, the accident wing spar was constructed of Sitka
Spruce (Picea
sitchensis). The failure surface of the spar was, "...spilt
cleanly into
two pieces by a force that was perpendicular to the direction
of the
grain." The report further stated, "It appears that the bolt
holes that
were drilled through the spars to accept the 1/4-inch bolts
were not all
drilled perpendicular to the spar's outer surfaces."
Examination of the
second hole from the inboard end, "suggests that this
particular hole was
drilled twice to make the bolt for this connection fit." The
report
stated, "...the holes that are on either side of the spar are
not evenly
spaced. There is also considerable difference in the diameter
of the
middle two holes relative to the diameter of the outer two
holes."
The full USDA Forest Product Laboratory examination report is
attached to
this report.

Any one know the history of N99763 Serial# 167. Built by KECSKES. I found an accident
report on it that stated, "landed hard; broke gear, broke wing spar.
No injuries.
I'm wondering if a very hard landing can injure (crack but not break) the main
spar connection to the fusalage.

Subject: Special EAA Announcement: Opposition to Newly Introduced Bill
EAA URGES MEMBERS TO OPPOSE OUTRAGEOUS HOUSE BILL
THAT WOULD SEVERELY RESTRICT GENERAL AVIATION
****************************************************************************
******************
The Experimental Aircraft Association is urging its members and all aviation
enthusiasts
to contact their Congressional representatives and strongly oppose a newly
introduced
bill by Rep. Anthony Weiner (D-N.Y.)
This bill (H.R. 5035) would require the Department of Homeland Security to
create a
method of screening all passengers and property on each flight of all
passenger
aircraft in the U.S., including general aviation aircraft of all types. It
would also prohibit
non-airline aircraft from flying within 1,500 feet of any structure or
building, and prohibit
non-airline aircraft from flying over any U.S. city with a population of 1
million or more.
It would further require that pilots of all aircraft in U.S. airspace remain
in contact with the
Federal Aviation Administration, presumably by radio, regardless of altitude
or location.
"The extreme shortsightedness of this bill speaks for itself and completely
counters the
government's own security experts, who have continually stated that general
aviation
does not pose a significant security threat to the U.S.," said Doug Macnair,
EAA's Vice
President of Government Relations. "It's sad that the solemn anniversary of
9/11 terrorist
attacks is being used to introduce this bill, which does nothing to enhance
security and smacks
of election-year grandstanding."
With 17,000 landing facilities and nearly 200,000 aircraft in the United
States, EAA maintains
that it is inconceivable that the Department of Homeland Security (DHS) and
FAA could ever
fund and administer such a plan. DHS and the Transportation Security
Administration have
repeatedly indicated that general aviation does not warrant such levels of
security when
compared to other transportation modes and threats.
"We as a nation need to focus our limited resources on the most serious
vulnerabilities
and threats to our security," Macnair added. "TSA has made extensive
studies of those
threats and nowhere has that agency ever suggested such draconian measures
as those
proposed in this bill."
EAA members and others can express their opposition to this bill to their
congressional
representatives by finding their contact information at
http://www.house.gov. EAA
immediately contacted members of the House Aviation Subcommittee to state
its
extreme opposition to this legislation.
