## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain Saab AB, Saab Aeronautics Model SAAB 2000 airplanes. This proposed AD was prompted by reports of loose and irregular fasteners at the forward end of the nacelle upper longeron, where the bulkhead frame and struts are attached to the engine mounting structure (EMS). This proposed AD would require modification of the EMS and structural attachments. The FAA is proposing this AD to address the unsafe condition on these products.
