Inaccurate airspeed indicator

I had a my two-year transponder/static system check while visiting my
mother
in San Antonio. When I departed, I noticed the airspeed didn't come up
like
it should. I attributed this to shifting winds and assumed I had a
slight
tailwind. Then in cruise, I did my normal operating performance check.
My
IAS was about 30 knots low, but my groundspeed was normal. I tapped on
the
airspeed indicator and it gained six knots. Question #1: How would a
transponder/static check screw up my airspeed? Was this just
coincidence?

In my experience, taking the airplane to the shop for something and
having it come out with something broken that worked just fine
previously is more the norm than the exception.

Frankly, Michael, you seem to hang out with a rough crowd. You keep saying
that the flight instructors are all incompetent, as are all the pilots, the
FAA, the mechanics, and everybody else. Are you the only person in the whole
world who is able to do his job? If so, then we should all take out a big
insurance policy on you. We will need it if anything happens to you and the
world stops turning as a result. :-)

you are forgetting Tarver to whom, Honeywell/Bendix/King, Boeing, the
FAA, the NTSB, Antonov Design Bureau, Collins, NASA and the Wright
Brothers all owe a debt of gratitude.
