Actually it's "person, vessel, or structure on the surface"... not that it
matters. At that height binoculars wouldn't even be necessary.
In today's paranoid society people seem to have 911 on speed dial on their
cellphones, and cellphone cameras in case they missed the N-number. And
there has been a lot of discussion recently, I forget whether it was on
this list or elsewhere, about self incriminating flying videos on youtube
leading to FAA enforcement action.
But in an ultralight there's no 500' rule; it would be completely legal...
I love my UltraStar!

DOW 4 Compound works for me. It is an inert electrical insulating compound in
the form of silicone grease that is designed to be compatible with metal, rubber
and plastic parts. It won't run off with heat either.
One of Dow 4's best uses is for O-ring installation, It lubricates and retards
"rolling" and poor seating of O-rings during installation.
Dow 4 is available through Aircraft Spruce and other suppliers. Please note that
I have no connection with Dow or Aircraft Spruce; just as a very satisfied
customer.

While you're doing the inventory, keep an eye out for the elevator bell
crank that installs in the cockpit and is connected to the stick with a push
pull tube. There was a running change made at some time in the 90's that
added a hole on the left forward corner of the bell crank for the cable from
the trim lever. Previous to this the trim lever connected to the elevator
with a cable that ran from the trim lever all the way back to the bell crank
in the tail and back again to the cockpit bell crank. When the trim lever is
moved from whatever the builder selects as the neutral point one part of the
cable goes slack and bangs around in the tail tube. While the noise by
itself is worrisome, when the trim cable is taut and the elevator control
cable is slack the elevator becomes kind of loosy goosy in turbulence.
There are two ways to fix the problem, call Travis and order the current
iteration of the cockpit bell crank, or use a longer bolt to attach the rod
end of the push pull tube and add a tang to provide the second hole for the
trim cable.
Another thing in the control circuits. I don't know if this is covered in
the instruction manual, it isn't on the Mk IIIC plans. Add AN 970 large area
washers to the outside of the rod end attachment bolt of the bell crank
described above and the two on the aileron bell crank for the ailerons.
This will keep the controls from becoming separated should the rod end come
apart.

The change must have been cut in very early on in the Mk III production. I
had a conversation with Travis about it when I first found it on my
aircraft. As I recall he had no record of it which would seem to indicate
the cut in was done before TNK took over from Homer. The serial number
stamped at the end of the engine mount tube on my aircraft is 043.
Truthfully, for all I know this may have been a builder mod. It doesn't look
like it, but it could be.

I have MKIII sn: M3-011.
Bro Jim and I were working at Homer's Dec 1990 to Mar 1991. Jim welded
up MKIII fuselages and I inspected them from the very first, M3-001. We
also built and modified my MKIII at night while there. Each morning,
when Homer Kolb came to work, he would inspect and approve what Jim and
I had done the night before.
My MKIII has the current forward aileron bell crank. I believe they all
do.
BTW: I don't add fender washers to my rod end bearings. Haven't
figured out how they could wear enough to separate. My MKIII rod end
bearings have over 3,000.00 flight hours on them and they are quite
serviceable. During my time flying Army helicopters, I do not remember
fender washers being added to rod end bearings.
I wanted to refresh my memory, so I walked over to the hanger and took a
close look at Larry Cottrell's FSII rod end bearings on his aileron
push/pull tubes. Looks like it would be pretty difficult to get the
small AN 1/4 inch washer through the hole if the bronze bearing totally
disintegrated.

Larry never flew the plane,,,, he started it a few time but never committ
ed aviation. on a early start, Larry twisted off the input shaft of his
one of a kind psru....(almost sure it was the input shaft,) the rebuild
of the psru kept having oil leak problems... he finally got the leaks re
solved,,, then the engine backfired during a start up and destroyed the
chain in the psru,,, that was or seemed to be the last straw before Lar
ry sold the plane.
I don't know if the new owner has or has not flown the plane. I have wond
ered the same thing during this thread.

John, I must assume, then, that my aircraft had an ill considered
modification to the elevator trim linkage.
As for the rod ends,
"Rod ends have been known to literally come apart after the peening
retaining the ball races somehow failed allowing the bearings to become
disconnected. It is the wise builder who takes the precaution of installing
a large diameter washer between the nut and bearing to prevent its total
failure. To be successful in preventing this type of failure, the washer
must have a diameter somewhat larger than the hole in the bearing
flange.".....Tony Bingelis, "Sportplane Construction Techniques"
Tony made this recommendation about carburetor linkages, but I've found the
same recommendation for control surface linkages in plans for the Long EZ
and Varieze, among others.
If you like videos, EAA has this.
http://www.eaavideo.org/video.aspx?v=1618638582
Did you not recount awhile back how, before adding aileron counterweights
you had to replace rod ends on a yearly basis as they wore? 60 cents worth
of washers seems like awfully cheap insurance to me.

John, I did some more digging in FAA publication AC 65-15A "Airframe &
Powerplant Mechanics Airframe Handbook" that might explain why you didn't
see any restraints to keep rod end bearings from coming loose and departing
the housing. On page 68, figure 2-61 is a cutaway view of rod end housing
that has a large flange on the bell crank side. The text accompanying the
drawing says, " It is possible for control rods with bearings to become
disconnected because of failure of the peening that retains the ball races
in the rod end. This can be avoided by installing control rods so that the
flange of the rod end is interposed between the rod end and anchored end of
the attaching pin or bolt as shown in figure 2-60. Another alternative is to
place a washer, having a diameter larger than the hole in the flange, under
the retaining nut on the end of the attaching pin or bolt."
I was able to cut the drawing from the page but the text caption didn't come
out the best in the transition to a jpg file.
I'm no helicopter mechanic, but that might explain why you didn't see large
area washers being used to safety the rod ends on helicopter controls. That
same capability was built into the rod end housing instead.

No, I didn't say that.
I did not have to change out aileron push/pull rod end bearings. I
changed out aileron push/pull rod end bearings that showed any sign of
play, 25 hours, 50 hours, whenever there was the slightest bit of play,
in an effort to prevent aileron flutter. Not because the ball was going
to pull out of the socket.
In my last post I shared I have aileron push/pull rod end bearings with
over 3,000.00 hours, lots of play/slop, and no aileron flutter with
aileron counterbalance weights installed.
I'm talking about 1/4" and 5/16" rod end bearings used on elevator and
aileron controls on Kolbs, not tiny rod ends used on throttle linkages.
There is a tremendous difference in durability and longevity between
tiny ones and large ones.
I have never seen or read a report where a 1/4" or larger rod end
bearing failed, especially on a Kolb.
First time I saw fender washers being used on rod end bearings was back
in the early days of ultralights. Probably came from the same book as
clear plastic fuel line so you can see your fuel. ;-)

I added the large washers to the controls on my UltraStar because it
definitely looked like a failed bushing could allow the bolt could pull
through the eye. Can't do any harm, and it adds peace of mind.
I recently replaced the larger (3/8") rod ends on my US engine mounts after
finding them badly worn. On these (I know because I just did it) the bolt
head and AN960 washer definitely could pass through the eye. I added AN970
washers there, too.
Does Kolb spec AN rod end bearings on the controls? On the US engine
