Applicability*9
This AD applies to all The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes, certificated in any category.
Compliance

Required actions
(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).
Unsafe condition
This AD was prompted by reports of uncommanded altitude display changes in the mode control panel (MCP) altitude window. The FAA is issuing this AD to address uncommanded changes to the MCP selected altitude; such uncommanded changes could result in incorrect spatial separation between airplanes, midair collision, or controlled flight into terrain.
Affected ADs
This AD replaces AD 2017-15-01, Amendment 39-18961 (82 FR 33782, July 21, 2017) (“AD 2017-15-01”).
