- What it does
The FAA is superseding Airworthiness Directive (AD) 2019-20- 07, which applied to The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2019-20-07 required repetitive operational checks of the leading edge (LE) outboard (OB) slats and applicable on-condition actions. AD 2019-20-07 also required revising the airplane flight manual (AFM) to prohibit flap retraction under icing conditions after landing and revising the existing maintenance or inspection program, as applicable, to incorporate a new operation check. This AD was prompted by the manufacturer developing further actions to address the unsafe condition. This AD continues to require all requirements of AD 2019-20- 07. This AD would also 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), which terminates the retained requirements of AD 2019-20-07. This AD also removes airplanes from the applicability. The FAA is issuing this AD to address the unsafe condition on these products.
