Airspeed Indicator problems

And then, there can be problems with sending instruments
in for a rebuild.

First, it was my altimeter. Off it went to a repair
shop in Kansas and came back with the glass cracked.
The crack went right to one of the screws. Damn.
Turn right around and send it back for 'warranty'
service. It has worked just fine since and that was
maybe three years ago.

Second, my airspeed indicator had a leak. I sent it
in to another shop in Kansas and authorized a check-up.
Turns out they tore it down and found it pretty much
all worn out and were in the process of starting to
totally rebuild it. Without my authorization. It
was going to cost around US$450. I told them to stop
and just send the instrument back to me. So, I bought
a new Winter airspeed indicator from Tim Mara at Wings
and Wheels for less than the rebuilt one would have
cost me.

I was hoping the old airspeed would just need a new
O-ring and a face cleaning.

Oh well.

The original Schweizer airspeed indicator in my glider
sticks.

The pitot line runs to the bottom port on the back
of the instrument
but not direclty. It has a tee that routes it off
to another
instrument also. I would have thought that the pitot
should have an
uniterupted tube going directly to the airspeed indicator.


Any advice would be appreciated.

I agree with the other posters---send it in for cleaning,
and calibration.

The tee is probably to a netto cappilliary, or possibly
to a hidden
diaphragm TE compensator.

A 10 cc medical syringe is a good 'air pump' for testing
systems.
