Airworthiness Directives; The Boeing Company Airplanes

The FAA is superseding Airworthiness Directive (AD) 2019-16- 05, which applied to all The Boeing Company Model 777 airplanes. AD 2019-16-05 required identifying the part number, and the serial number if applicable, of the Captain's and First Officer's seats, and applicable on-condition actions for affected seats. This AD was prompted by reports of uncommanded fore/aft movement of the Captain's and First Officer's seats. This AD retains the requirements of AD 2019- 16-05 and adds an inspection of previously omitted part numbers. The FAA is issuing this AD to address the unsafe condition on these products.
