Airworthiness Directive · Amendment 39-19856 · Auto flight
The Boeing Company Airplanes
This AD applies to all The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes, certificated in any category.
The FAA is superseding Airworthiness Directive (AD) 2017-15- 01, which applied to certain The Boeing Company Model 777 airplanes. AD 2017-15-01 required replacing the existing mode control panel (MCP) with a new MCP having a different part number. This AD retains the requirements of AD 2017-15-01, expands the applicability to include certain other airplanes, and adds a new requirement for certain airplanes to identify and replace the affected parts. This AD was prompted by a determination that the affected parts may be installed on airplanes outside of the original applicability of AD 2017-15-01. The FAA is issuing this AD to address the unsafe condition on these products.
(1) For the purposes of this AD, an affected part is an MCP having part number S241W001-201, S241W001-202, S241W001-251, S241W001-252, or S241W001-261.
(2) For the purposes of this AD, later-approved parts are only those parts that are approved as a replacement for the applicable part identified in Boeing Special Attention Service Bulletin 777-22-0034, dated March 3, 2016; and are approved as part of the type design by the FAA or The Boeing Company Organization Designation Authorization (ODA) after March 3, 2016 (the publication date of Boeing Special Attention Service Bulletin 777-22-0034, dated March 3, 2016).
This paragraph restates the requirements of AD 2017-15-01, with revised compliance language. For airplanes identified in Boeing Special Attention Service Bulletin 777-22-0034, dated March 3, 2016, within 60 months after August 25, 2017, (the effective date of AD 2017-15-01): Do the actions specified in paragraph (h)(1) or (2) of this AD.
(1) Replace the existing MCP part with an MCP having part number S241W001-262, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-22-0034, dated March 3, 2016.
(2) Install a later-approved part as defined in paragraph (g)(2) of this AD.
For airplanes not identified in paragraph (h) of this AD with an original airworthiness certificate or original export certificate of airworthiness issued on or before the effective date of this AD, do the actions specified in paragraphs (i)(1) and (2) of this AD.
(1) Within 60 months after the effective date of this AD, perform a general visual inspection of the MCP to determine the MCP part number. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the MCP can be conclusively determined from that review.
(2) If the MCP is an affected part, within 60 months after the effective date of this AD: Do the actions specified in paragraph (i)(2)(i) or (ii) of this AD.
(i) Replace the existing MCP with an MCP having part number S241W001-262, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-22-0034, dated March 3, 2016.
(ii) Install a later-approved part as defined in paragraph (g)(2) of this AD.
