## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2019-03-19, which applies to all Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. AD 2019-03-19 requires a functional check of certain fuel probes, and replacement with a serviceable part if necessary. Since the FAA issued AD 2019-03-19, the agency has determined the definition of a ``serviceable part'' must be revised. This proposed AD would retain a functional check of certain fuel probes, and replacement with a serviceable part if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
