## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2019-20-07, which applies to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2019-20-07 requires repetitive operational checks of the leading edge (LE) outboard (OB) slats and applicable on- condition actions. AD 2019-20-07 also requires revising the airplane flight manual (AFM) to prohibit flap retraction under icing conditions and revising the existing maintenance or inspection program, as applicable, to incorporate a new operation check. Since the FAA issued AD 2019-20-07, the manufacturer developed further actions to address the unsafe condition. This proposed AD would retain all requirements of AD 2019-20-07 and would require replacing the LE outboard geared rotary actuator (GRA) with a LE outboard lockout actuator (LEOLA) at leading edge OB slat locations and revising the existing maintenance or inspection program, as applicable, to incorporate a new certification maintenance requirement (CMR). This proposed AD would also remove airplanes from the applicability. The FAA is proposing this AD to address the unsafe condition on these products.
