The Boeing Company is proposing a new airworthiness directive (AD) for certain 747-400 and 747-400F models to address malfunctions in the integrated display unit (IDU) and mode control panel (MCP), which could impair flight crew control. The proposed AD involves installing new software, replacing duct assemblies, and making wiring changes to prevent IDU malfunctions.
