If it fits, maybe you're insulting your own intelligence.

It's interesting that you use an insult to make a point - I will pass on
that... That's two insulting posts I've received in the past couple of

Go down to the vet supply store and get one of those big horse hypodermic
needles with the smallest needle you can get.

Go to the craft store and get a suction cup that will fit over the static port.

CAREFULLY and with GREAT CAUTION put the suction cup over the static port. If
you have two static ports, put another suction cup over the other port. (A thin
coating of spit on the suction cup works well as a vacuum seal, so does a thin
coating of vaseline.)

Pick ONE of the static ports and push the needle through the backside of the
suction cup. SLOWLY and with GREAT CAUTION suck down the suction cup until the
altimeter reads about a thousand feet above airport elevation OR the airspeed
indicator reads just at the yellow arc, whichever occurs first.

You MUST support the syringe so that the needle doesn't cock and let the suction
cup leak. I've got mine arranged so that there is a 6' length of plastic tubing
between the syringe and the needle, tied off with tiewraps. Don't believe that
the aircraft system has a leak until you've tried your little setup on a known
good airplane and it doesn't show leak.

Let the system come to equilibrium for five minutes or so. If the ASI is still
slowly bleeding off speed after five minutes OR the altimeter continues to wind
down, you've got a static leak. You can repeat the suckdown after five minutes
if you wish, but if the thing doesn't stabilize after two or three iterations,
you've got a leak on your hands.

You may want to do the mason jar accumulator trick I showed when writing about
the altitude encoder test jig (www.rstengineering.com and go to bibliography or
www.rstengineering.com/kitplanes and download the article).

Of course, I would NEVER do this test on a standard certificated aircraft.
Nosirre, not me, not never. Huh, unh.

This test should have been performed as part of
-the pre-buy so that you wouldn't not have been responsible for the
-entire cost of the instruments and the labor.

Update!!! My diaphragm in the ASI has a leak BER and my TC is not worth
being serviced I am just going to get new replacements nice little $1,000
bill and a 1 week wait but at leased i will know what i have.

Well my bird spent 6 hours at the avionics/instrument shop today getting a
pito static & transponder encoder check now the results


Transponder/Encoder Working 100% To 20,000 feet
Altimeter Working 100% Well With in Specs To 14,000 feet did not go higher
then aircraft service ceiling
VSI Working 100%
Static System Pass
Pito System Fail Has Leak In System = Traced To Airspeed Indicator Leak on
Pito Side Needs Rebuilt Anyone know of a good place to a rebuild

have
done or a decent replacement?
Turn Coordinator Bad = Barings Making Noise Needs Rebuilt Anyone

know
of a good place to have a rebuild done or a decent replacement?
1 Vor Head OK
1 Vor Head W/ Glide Slope Bad = Localizer Works Great, Vor Is Off 8

Degrees,
Glide Slope don't go to full deflection Non serviceable needs replaced.

Other than my first bill in owning was a fun exciting day in the shop they
were very friendly and explained everything that they were doing and

answerd
all my questions i really learned how all the insturments work kinda cool

if
i decide to replace instrad of rebuild ill have some that i can take apart
and play with.

It is a great learning experience "the pleasures of ownership" I don't mind
spending money on toys I did the ATV thing for a while 1 trip to the dunes
could run $3,000+ and flying is more fun and more rewarding i belive, Now I
get to make the decision of what ASI I want to install do I want a Standard
or True Airspeed? Humm its hurting my brain deciding witch one to get price
difference is min as I am already going to have to be spending $420.00 on a
standard or should I spend a bit extra $490 on a true airspeed witch would
be best?

in a Cessna 150?? do you think you'll need to compute TAS? or do you think
your GPS will provide you what you need.

Just wondering if it is worth the extra $60.00 to have a little extra.

Never mind trying to justify it, just spend the extra money. If
you're thinking like this now and you don't do it, you'll always
regret it (except, of course when you sell it).

Have you ever used an ASI with a TAS knob? I have pretty good vision and
I go crosseyed trying to set the temperature opposite the altitude.
