## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2021-10-02, which applies to all Bombardier, Inc., Model BD-700-1A10 and BD-700-1A11 airplanes. AD 2021-10-02 requires repetitive general visual inspections of the left- and right-hand elevator torque tube bearings for any sand, dust, or corrosion; repetitive functional tests of the elevator control system; and replacement of the elevator torque tube bearings if necessary. Since the FAA issued AD 2021-10-02, the FAA has determined that a new airworthiness limitation is necessary. This proposed AD would continue to require certain actions in AD 2021-10-02 and require revising the existing maintenance or inspection program, as applicable, to incorporate new airworthiness limitations. The FAA is proposing this AD to address the unsafe condition on these products.
