Safety Recommendations from the investigation report:

Boeing should improve the reliability of the radio altimeter system.

The FAA and EASA should ensure that the undesirable response of the autothrottle and flight management computer caused by incorrect radio altimeter values is evaluated and that the autothrottle and flight management computer is improved in accordance with the design specifications.
