My SL30 failed recently - could not transmit or receive. The casing was alot
hotter than normal after 30mins use and there was a noticeable burnt electronics
smell from the back plugs.

On my last conditional, I found, of course some wear in on the main
bearings. But I also found that both main wheel pant brackets had
excessive slop in the mounting hardware. The nuts had not loosened at
all, but the spacer material to offset the brackets had worn in. Once I
tightened this all up and repacked my bearings, I only have occasional
shudder during various taxi scenarios. Don't know which side is the
culprit, or if it is both. I also found the nylock nuts on the wheels
themselves to be loose. I assume with the heat from braking being
transferred to the wheels the nylon became hard and began to fail. I
upgraded the wheel half nuts to all metal to hopefully stop them from
backing off.

Sean at Planearound.com makes a great replacement spacer
that will get rid of the slop permanently. Now that you've
tightened it up again, it will be OK for a while but eventually
will wear further and further until finally the hole is worn
thru and you need to replace the whole large bracket, so it's
probably worth checking into another option rather than
just retorquing.

Points well made.
Getting someone with a working and mounted SL30 to swap mine into would
be ideal. Haven't been able to do that.
I'm comfortable slipping someone elses into mine because of the symptoms
but I know that I would feel compelled to replace anyone's unit I
damaged at full cost. Not something I would want to do but would do it
without hesitation in this situation.

I haven't had any shimmy at 175 hours. Half of my operations are off a
relatively rough grass strip and I don't think any shimmy would be
detected during those ops. However, I'm guessing that any wear that
would cause a shimmy would be accelerated. We'll see.

| Subject: | Re: Skybolt Fasteners - Installation |
I like the sky bolts, but I only put them across the top of the cowl. Their instructions
are poor, but mind the recommended spacing that they suggest and you
will be ok. They are very expensive, but to my mind worth it in THIS AREA ONLY.
They are good because they save a lot of time removing the cowl when you are
flight testing, when you should remove the cowl after each flight.

| Subject: | Re: Main gear shudder revisited |
I did not have any shudder/shimmy during phase 1 and on into phase 2. I'm not sure
exactly when it started, but probably not until I had 100 or more hours on
the airplane. I can't find any wear anywhere in the gear that might make it shimmy.
I've re-torqued the main gear bolts and that has not changed anything.
I have thought about re-torquing those bolts with the airplane on jacks. Would
that make any difference?
It sounds like the wooden stiffener that has been fairly successful on the other
RV's might be worth exploring. Is anybody going down that path?

Sean at Planearound.com makes a great replacement spacer
hat will get rid of the slop permanently. Now that you've
ightened it up again, it will be OK for a while but eventually
ill wear further and further until finally the hole is worn
hru and you need to replace the whole large bracket, so it's
robably worth checking into another option rather than
ust retorquing.

| Subject: | Matco Front Wheel and Desser Stem |
I was putting the front wheel together today. I have the Matco nose
wheel and Desser 500-5 tube with the TR-67 stem as recommended by many
others.
Where the stem goes through the rim, there are not enough threads to use
the locking nut to secure the stem to the rim. I've seen other pictures
where the locking nut is not even used. Has that been ok to skip?
Thanks,

I installed Sean's spacers 2 years ago and that eliminated main wheel shudder for

NTSB: Homemade aircraft deadlier than most planes
By Bart Jansen, USA TODAY
Pilots of small, homemade aircraft have twice as many accidents and
three times the fatalities as the rest of the general-aviation
community, the National Transportation Safety Board found Tuesday.
2011 photo by Eric Seals, Detroit Free Press
Tom Vukonich works on a De Havilland DH-4B wooden bi-plane in his garage
in Metamora, Mich. The NTSB approved recommendations for the FAA and
Experimental Aircraft Association to improve safety.

Tom Vukonich works on a De Havilland DH-4B wooden bi-plane in his garage
in Metamora, Mich. The NTSB approved recommendations for the FAA and
Experimental Aircraft Association to improve safety.
Based on those findings, the five-member board unanimously approved
recommendations for the Federal Aviation Administration and the
Experimental Aircraft Association to develop better flight-test plans,
encourage more training for pilots and conduct fuel tests on the
aircraft. Engine failures are a leading cause of the accidents.
"The recommendations that we have issued today are all intended to
improve safety while maintaining the excitement and the adventure of
this vibrant segment of aviation," says Deborah Hersman, the board
chairman.
The board studied the experimental aircraft industry because of the
larger number of accidents during the last decade and because of the
growing popularity in aircraft that hobbyists build themselves. Over the
last decade, there were an average of 213 accidents each year, including
55 fatalities, the board found.
Among 224,000 general-aviation aircraft across the USA, 33,000 are
considered experimental, meaning they were built from a kit or from a
unique design. The aircraft account for 20% of fatal crashes of general
aviation, despite representing a small portion of the fleet.
=46rom 2001 to 2010, the board found that accidents for every 100,000
hours flown averaged 21.2 for experimental aircraft and 9.5 for the rest
of general aviation. Even more ominous, the average number of fatal
crashes for every 100,000 hours flown averaged 5.3 for experimental
aircraft and 1.6 for the rest of general aviation.
During that decade, the board found nearly one in four accidents were
blamed on a power-plant failure and another one in four on loss of
control in flight. Loss of control caused nearly half the fatal crashes.
Loren Groff, who researched the accidents, says experimental aircraft
have lower accident rates in Canada and Britain. He says those countries
have more inspections of the aircraft, including a fuel-flow check in
Canada, that could prevent engine failures.
"It seems like we would want to be doing things they are doing in other
countries," says Robert Sumwalt, a board member.
A significant share of the accidents occurred during the first flight of
the aircraft, whether the pilot built the plane himself or bought it
used. The board found 10 of 102 accidents in newly built aircraft were
on the first flight, as were 14 of 125 on the first flight of used
aircraft flown by the new owner.
With the help of the Experimental Aircraft Association, the NTSB
surveyed nearly 5,000 pilots to learn more about the industry. The
survey found that experimental pilots tend to be older and experienced,
mostly describing themselves as retired and averaging more than 60 years
old with 30 years of flying experience with a total of 1,300 hours.
The vast bulk of the aircraft are planes, but also include gliders,
helicopters and balloons.
