As our Mooneys age, so does the sealant in our fuel
tanks. The original life expectancy of the sealant is somewhere between 10 and
20 years. We are seeing planes with sealant double that age. As the sealant
has aged, it has become more rigid or brittle. The normal vibrations and
resonance of the airframe causes the sealant to break apart at the molecular
level. At this point, you start seeing
blue fuel stains appear around the wing and smell fuel fumes in the cockpit.
