Dear Listers,
Some have asked, "What's my Contribution used for?", and this is
certainly a valid question. Here are just a few examples of what
your direct List support enables. It provides for the very
expensive, business-class, high-speed T1 Internet connection used on
the List, insuring maximum performance and minimal contention when
accessing List services. It pays for the regular system hardware and
software upgrades enabling the highest performance possible for
services such as the Archive Search Engine and List Browser. It pays
for 16+ years worth of online archive data available for instant
random access. And, it offsets the many hours spent writing,
developing, and maintaining the custom applications that power this
List Service such as the List Browse, Search Engine, and PhotoShare.
But most importantly, your List Contribution enables a forum where
you and your peers can communicate freely in an environment that is
free from moderation, censorship, advertising, commercialism, SPAM,
and computer viruses. How many places on the Internet can you make
all those statements about these days? I will venture to say - next to none...
It is YOUR CONTRIBUTION that directly enables these many desirable
aspects of this most valuable List service. Please support it today
with your List Contribution. Its one of the best investments you can
make in your Sport...

--> RV6-List message posted by: alan@reichertech.com
Hello, All!
Please pardon this intrusion. This note is not specific to your
particular list, but regardless of what you are building, restoring, or
flying, an issue exists that could potentially affect all of you who fly
in the United States. That issue is the Washington DC ADIZ.
This ADIZ was put into effect as a temporary protective measure for
Washington DC airspace after 9/11. There is now an NPRM out to make this
airspace *permanent*.
The original comment period for this NPRM expired yesterday, November 2.
However, the FAA has now extended the comment period for another 90 days,
so if you did not get your comments in, HERE IS YOUR CHANCE!
Information on the ADIZ, and why we are fighting it, can be found here:
http://www.aopa.org/adizalert/
I live underneath the current DC ADIZ, so I get to play with this every
time I fly. The AOPA page above gives a good summary of what has happened
in this area since it's inception.
Help on formulating comments for this NPRM can be found here:
http://www.aopa.org/adizalert/help.html
Comments on this NPRM can be submitted (online) to the DOT here:
http://dms.dot.gov/submit/
Instructions on how to navigate and fill out the DOT page to submit your
comments are available here:
http://www.aopa.org/adizalert/faa_help.html
There are over 18000 comments against this NPRM at this time. If yours is
not one of them, please take the time now to submit your comments; every
one helps. If this ADIZ becomes permanent, then there could be an ADIZ
coming to an airspace near you in the future!
I thank Matt for allowing me to send this to you. Even if you don't live
near the DC area, please do what you can to protect your flying
priviledges... submit your comments!
Regards,

| Subject: | Finally fixed my 6A nose gear shimmy |
--> RV6-List message posted by: Ron Lee <ronlee@pcisys.net>
Recently I have been plagued by a persistent, unresolved
nose gear shimmy in my RV-6A. I tried adjusting the
breakout force (higher) and different nose tire pressures.
Nothing helped. Then last Sunday I had a friend videotape
me taxiing at the speed (18 knots) where the shimmy could
be counted on. There was no oscillation in the horizontal
plane consistent with shimmy. But there was an obvious
Up/Down motion of the nose wheel assembly.
This led to the checking of the balance and it was significantly
out of balance. After balancing the nose wheel/tire I again
taxied and there was no longer a vibration at/above 18 knots.
However, there was another vibration above 23 knots. Not
encouraging. I considered taking off the wheelpant to see if
that was factor but was able to get someone to observe me
taxiing at that speed. Lo and behold it was not the nosewheel
but the left main. So I remove it and not only was it out of
balance but out of round. It was an Air Hawk but perhaps
something I did caused the out of round condition.
I replaced both main tires and balanced them and this morning
flew. No vibrations!
Analysis/recommendations:
I was incorrectly diagnosing the vibration of the nose wheel/tire
as shimmy when it was out of balance.
I incorrectly diagnosed a main wheel/tire vibration as nose
wheel/tire shimmy/vibration.
From now on I will balance every wheel/tire after changing the
tire. The left tire had a weight on it but I am not sure that it was
from the previous tire change.
If I develop a vibration again my first step will be to have someone
on the ground visually observe and/or videotape the wheels/tires
to isolate the offender(s). Had I done that first I would have quickly
resolved the problem without all the failed fix attempts.
I went to three auto parts stores to find the lead weights with
adhesive backing and none had them. I did get some from a
motorcycle shop and from my normal tire store (Discount Tire -
half the price of the motorcycle shop).
Conclusion: Now my taxiing is vibration free and my greaser
landings are no longer followed by vibration. Smooth landings
and a smooth rollout is so sweet.
