Airworthiness Directive · Amendment 39-18961 · Auto flight
The Boeing Company Airplanes
Superseded. A later AD replaced this one: AD 2020-04-19. Comply with the one in force.
This AD applies to The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes, certificated in any category, identified in Boeing Special Attention Service Bulletin 777-22-0034, dated March 3, 2016.
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 777 airplanes. This AD was prompted by reports of uncommanded altitude display changes in the mode control panel (MCP) altitude window. This AD requires replacing the existing MCP with a new MCP having a different part number. We are issuing this AD to address the unsafe condition on these products.
Within 60 months after the effective date of this AD: Replace the existing MCP part with a new MCP part having a different part number, in accordance with the Accomplishment Instructions of Boeing Special Attention Service Bulletin 777-22-0034, dated March 3, 2016.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
