  SUPPLEMENTARY INFORMATION: As published, Airworthiness Directive 2020-
  24-04, Amendment 39-21334 (85 FR 77991, December 3, 2020), requires 
  revising the existing AFM to incorporate procedures for conducting an 
  approach with a localizer-based navigation aid, monitoring localizer 
  raw data, calling out any significant deviations, and performing an 
  immediate go around if the airplane has not intercepted the final 
  approach course as shown by the localizer deviation. AD 2020-24-04 
  applies to all The Boeing Company Model 787-8, 787-9, and 787-10 
  airplanes.
      As published, the regulatory text included errors in certain 
  references to the AFM that is required to be revised. The location of 
  the AFM text to be revised is incorrectly identified as the 
  ``Limitations section''; the correct location is the ``Operating 
  Procedures chapter.'' In addition, the figure incorrectly identified 
  the heading of the AFM text as ``Operating Instructions''; the correct 
  heading is ``Autopilot Flight Director System--Operating 
  Instructions.''
  
  Correction of Publication
  
      This document corrects an error and correctly adds the AD as an 
  amendment to 14 CFR 39.13. Although no other part of the preamble or 
  regulatory information has been corrected, the FAA is publishing the 
  entire rule in the Federal Register.
      The effective date of this AD remains December 18, 2020.
      Since this action only corrects errors in certain AFM references, 
  it has no adverse economic impact and imposes no additional burden on 
  any person. Therefore, the FAA has determined that notice and public 
  comment procedures are unnecessary.
