I've been having airspeed indicator problems recently. Earlier in the year I went flying and found the airspeed inop...found water in the static line. A little while later I flew through a rain storm but had no issues with the airspeed during that flight. The next time i went up it wasn't working again. I found water in the static line again but even after cleaning it out the airspeed indicated about 5 mph high. Something on the static side plugged...right? Any ideas? Time for a new ASI?

Cracked or broken line from inlet to gauge? Had kinda the same problem once on the 170...replaced the whole line. There was a check you can do on the indicator but the proceedure for your plane may be different than mine...ask your IA.

I had that problem in my 172 a few years ago, it turned out to be a cracked line from the pitot tube to the gauge, it appeared to have been cracked when it was installed at the factory in 1956. after I replaced the line I got 5 mph faster readings on the gauge as well. I also installed a low-point-sump in the line when i repaired it.
