Airworthiness Directive 2019-20-07
recurringAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
The FAA is adopting an airworthiness directive (AD) for all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD requires repetitive operational checks of the leading edge (LE) outboard (OB) slats and applicable on-condition actions. This AD 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. This AD was prompted by a determination that the LE OB slat system could be out of position without flight deck annunciation. The FAA is issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2019-20-07 applies to
Whether AD 2019-20-07 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
