A couple years ago, a local flyer with a Hawk and a dual carb 503
experienced an unusual failure, the chrome facing on his K & N air filter
fell off in flight. It went through his Ivo with just a moderate ding, but
ever since then, I have kept a close watch on mine.
Finishing up the annual yesterday, I gave the air filter a close scrutiny
and discovered that my K & N's chrome facing was loose along one half of
one side. Took a thin screwdriver and very easily separated the rest of the
facing from the filter, only one small area actually gave much resistance
to turning loose.
Threw the facing in the trash, the filter is not as pretty now, but all in
all, it's a good trade off. Just thought I'd pass this along. And archive it.

Dimple tape has very tiny little holes that change the flow at a very small
scale. The whale bumps are large with probably 10 of them across a 10 foot
flipper. They are a very effect flow control with much more power then
dimple tape.

Hey Richard / Guys,
My (double) K&N filter was bought 1 1/2 yrs ago , and they had
stopped putting that chrome piece on it....I thought they were just getting
cheaper/cutting costs , but maybe their were more problems with them than we've
heard...

I had a similar problem with my full swivel tail wheel on my MKIIIc on the
way to Oshkosh last year but I was able to control it with brakes long
enough to get if parked out of the wind. The winds were app. 25 mph and this
is quite a bit for any light plane. I found that the springs that were
supplied with the Kolb kit were too weak. In a cross wind the tail would
swing enough to cause the tail wheel to swivel to the unlock point even with
full opposite rudder. Last fall I switched to compression springs which are
somewhat stronger but more importantly they have limits before they run out
of travel and allow you to counter a large cross wind. The problem I then
found was that the new springs didn't allow the tail wheel to swivel enough
to unlock. I had to drill some holes in the tail wheel horn to get the
enough rotation for it to unlock. Finally I have fairly positive control of
the tail wheel without the need for brakes and it will unlock but only when
I step on the brake and rudder fully deflected. The steering is a bit
quicker but since it is so positive it is easy to adjust to.

Must be a real bear when a humpback stalls....what's the recovery

Folow-up:
Today I got a chance to look at an older K&N - (1995 model?) for a 532/582,
and it had the chrome outside part, but looking at it from the inside,
through the throat openings, it is made different from the new ones. The
new ones (mine is a 2003 model - I guess that is new) (don't know when they
switched over) are all rubber with a chrome fascia crimped/glued on. The
old one was rubber where it attached to the carbs, then the wire/fuzz
matrix, and then the chrome was glued to it with a lot of rubber. There was
no secondary rubber surface under the chrome. It looked really solid, no
chance of detaching.
The new one that I stripped the fascia off of yesterday was primarily
attached around the edge, and then also in the middle where the embossed
oval ridge is, with the K&N logo in the middle. There was no glue or
adhesion anywhere except the middle and the extreme edge. Not good.

Hey Guys,
For any of you that have not heard the news: THE SPORT PILOT RULE HAS BEEN RELEASED
BY OMB AND IS AWAITING PUBLICATION BY THE FAA. I know there will be detractors
and it may be a while before it's in operation but its here love or hate
it.

The following is excerted from John's latest, postmarked early this morning...
I do have a tire problem, slow leak, which scares me a little. It may
be a pulled valve stem in the tube and have a catastrophic failure at
any time, rather than a simple slow leak.
I found an inner tube with the 90 degree valve stem at Lowes in
Anchorage today. Soon as I can get my hands on the proper tools, I will
pull the wheel and replace. Because of the leak, I had to overinflate
both tires to compensate. Then landed on Jim Stocker's gravel strip on
the banks of the Knik River here in Palmer. This large gravel was rough
on the little airplane with hard tires. As soon as the new tube goes
in, I can drop them back down to 6 or 8 psi. They'll work a lot better
down here.
Got my first shot of Mt McKinley yesterday. What an exciting flight, 45
miles out of Talkeetna into the big
mountains. Then to top it off, flew until after midnight, last night,
up to the Knik Glacier and the surrounding glaciers and mountains. Shot
some approaches into unimproved strips up in the mountains. Beautiful terrain.
Hard to express the beauty and the ruggedness of them.
Soon as I get the airplane flying I will head out to the Kenai Peninsula
for some sight seeing and visiting. When I am flown out in this area
will return to North Pole and see if I have a shot at the North Slope.
Other than the extra effort of being "on the road" living with others
and making do, this is the greatest flight I have ever experienced. Not
having to return to Oshkosh has been a blessing. That alone accounts
for the extra flying and visiting places that would be missed because of
the time constraint. This trip I am free to fly. :-)
