Description
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. This AD was prompted by reports of an uncommanded change to the mode control panel (MCP) selected altitude. It requires replacing the existing MCP with an updated MCP and performing an installation test to address the unsafe condition. The AD aims to prevent controlled flight into terrain or traffic conflict that could result in mid-air collision.
