| Subject: | Re: Flat main tire on takeoff or landing |
Thanks Rafael for sharing your experience. That makes me feel a little
more confident that landing with a flat isn't too bad.
Sure glad I was at my home airport with the right sized wing-jacks and
other tools available. As you said, there doesn't seem to be any way to
move the plane until after the wheel pant is removed and the tire changed.
Blue Skies,
Jeff

Unfortunately there is not an easy way to check tire pressure on the RV
without removing the whole wheel pant which is a lot of screws. It had
been checked just two weeks earlier though during a condition inspection.
On this day the tire had looked fine during pre-flight and rolled out of
the hangar easily and taxied normally. The deflation happened suddenly
during the taxi from the run-up area to the active runway.
Interesting tip about the newer style of tubes though. I'll investigate
that. Thanks.

I cut a hole in my wheel pants and put a spring loaded small door that I
got from ACS. I then went and got a straight pressure gauge from Sears. I
check mine every two weeks because of crappy tubes that leak. I will be
changing them next set of tires.

RV pilots at our airport have cut small holes in their wheelpants, and use a valve
stem extender that they spin on to the valve stem. When not checking tire
pressures, they plug the holes with metal snap-in hole plugs that fit almost
flush to the surface. It seems to work very neatly and the plugs can be painted
to match the wheelpant and be almost invisible.
The top plug in the picture on this page is pretty much the one they're using:

I'm pretty sure the extensions they found locally are 6" long, but this is the
only example I could find with Google:

Hi dear friends,
I just got my one servo that I ordered to check it out.
It looks like they can be modified to hold an encoder.
