AD 2020-24-04 The Regulatory Text Of The Original AD Included Errors In Certain References To The AFM

The FAA is correcting an airworthiness directive (AD) that published in the Federal Register.

That AD applies to all The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. As published, the regulatory text of the AD included errors in certain references to the airplane flight manual (AFM) that is required to be revised. This document corrects those errors. In all other respects, the original document remains the same. This correction is effective December 18, 2020. The effective date of AD 2020-24-04 remains December 18, 2020.

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.”
