## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2017-21-05, which applies to certain Saab AB Model 340A (SAAB/SF340A) and SAAB 340B airplanes. AD 2017-21-05 requires revising the existing maintenance or inspection program, as applicable, to incorporate airworthiness limitations, including new inspection tasks for the drag brace support fitting of the main landing gear (MLG) and to implement corrosion prevention and control program (CPCP) related tasks. Since the FAA issued AD 2017-21-05, the FAA has determined that new or more restrictive airworthiness limitations are necessary. This proposed AD would continue to require the actions in AD 2017-21-05 and would require revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
