Airworthiness Directive · Amendment 39-19482 · Navigation
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 787 series airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787 series airplanes. This AD was prompted by reports that, under certain conditions, the automatic dependent surveillance-broadcast (ADS-B) out function and air traffic control/ traffic alert and collision avoidance system (ATC/TCAS) functions can transmit incorrect data. This AD requires an inspection or records review to determine if certain software is installed, the installation of new software for the integrated surveillance system (ISS) operational program software (OPS) if necessary, a software check, and applicable on-condition actions. For certain airplanes, this AD also requires the installation of new software for the ISS OPS, ISS option selection software (OSS) file, and ISS airline selectable option (ASO) file; and installation of a new ISS definition file database within the displays and crew alerting (DCA) system. We are issuing this AD to address the unsafe condition on these products.
For airplanes that have an original certificate of airworthiness or export certificate of airworthiness issued on or before the effective date of this AD: Within 12 months after the effective date of this AD, inspect to determine if integrated surveillance system (ISS) operational program software (OPS) part number (P/N) COL40-0010-0100 or COL46-0007-0100 is installed. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the software can be conclusively determined from that review.
If, during any inspection or records review required by paragraph (g) of this AD, any ISS OPS P/N COL40-0010-0100 or COL46-0007-0100 is found: Within 12 months after the effective date of this AD, do all applicable actions identified as “RC” (required for compliance) in, and in accordance with, the Accomplishment Instructions of Boeing Alert Service Bulletin B787-81205-SB340036-00, Issue 001, dated June 30, 2017; except where Boeing Alert Service Bulletin B787-81205-SB340036-00, Issue 001, dated June 30, 2017, specifies installing software P/Ns COL41-0010-0101 and COL44-0007-0102, this AD requires installing P/Ns COL41-0010-0101 and COL44-0007-0102, or later-approved software versions. Later-approved software versions are only those Boeing software versions that are approved as a replacement for the applicable software, and are approved as part of the type design by the FAA or the Boeing Commercial Airplanes Organization Designation Authorization (ODA) after issuance of Boeing Alert Service Bulletin B787-81205-SB340036-00, Issue 001, dated June 30, 2017.
For Group 1 airplanes identified in Boeing Alert Service Bulletin B787-81205-SB340036-00, Issue 001, dated June 30, 2017: Prior to accomplishment of the actions required by paragraph (h) of this AD, install new software for the ISS OPS, ISS option selection software (OSS) file, and ISS airline selectable option (ASO) file; and install a new ISS definition file database within the displays and crew alerting (DCA) system; in accordance with the Accomplishment Instructions of Boeing Service Bulletin B787-81205-SB340005-00, Issue 002, dated April 27, 2016; except where Boeing Service Bulletin B787-81205-SB340005-00, Issue 002, dated April 27, 2016, specifies installing certain software, this AD requires installing that software or later-approved software versions. Later-approved software versions are only those Boeing software versions that are approved as a replacement for the applicable software, and are approved as part of the type design by the FAA or the Boeing Commercial Airplanes ODA after issuance of Boeing Service Bulletin B787-81205-SB340005-00, Issue 002, dated April 27, 2016.
