## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all Saab AB, Support and Services Model SAAB 2000 airplanes. This proposed AD was prompted by a report of inadvertently reversed connections of the outboard and inboard channel harnesses of the wheel speed transducers in the main landing gear (MLG) wheel axles. This proposed AD would require an inspection for correct installation of the MLG anti-skid system harnesses and corrective actions if necessary, as specified in a European Union Aviation Safety Agency (EASA) AD, which will be incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.
