Airworthiness Directive · Amendment 39-21265 · Flight controls
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 787-8 and 787-9 airplanes, certificated in any category.
The FAA is superseding Airworthiness Directives (ADs) 2015-14- 07, 2016-07-10, and 2016-24-09. AD 2015-14-07 applied to certain The Boeing Company Model 787-8 airplanes. AD 2016-07-10 and AD 2016-24-09 applied to all The Boeing Company Model 787-8 and 787-9 airplanes. ADs 2015-14-07, 2016-07-10, and 2016-24-09 required actions related to certain flight control module (FCM) software. This AD requires installing flight control electronics (FCE) common block point 5 (CBP5) software, which terminates the requirements of the ADs superseded by this AD. This AD was prompted by certain deficiencies in the FCM software, including a report of an unannunciated dual symmetric inboard slat skew. The FAA is issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of the introductory text to paragraph (g) and paragraphs (g)(1), (2), and (4) of AD 2015-14-07 (paragraph (g)(3) of AD 2015-14-07 is not retained in this AD), with no changes.
