Here in Oklahoma a few years ago our club 2-33 had a malfunction of the airspeed, turned out to be a nasty smelling decaying remains of some kind of insect in the pitot tube, could have easily gotten into the instrument. on my own sailplane I have installed small engine paper element filters to minimize the possibility of contaminates getting into my spendy instruments.
