Why Is My Airspeed Leaking?

All mechanical airspeeds have sealing gaskets, bezel gaskets and diaphragms. Any one of these parts can cause the airspeed to leak. Age, over pressuring the diaphragm and environment will cause gaskets to deteriorate over time. Its also important to check all lines, tubing or hoses that run through the pitot system for cracks or breaks. Make sure all connections and fittings are properly sealed.
