## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2017-15-01, which applies to certain The Boeing Company Model 777 airplanes. AD 2017-15-01 requires replacing the existing mode control panel (MCP) with a new MCP having a different part number. Since we issued AD 2017-15-01, the FAA has determined that the affected parts may be installed on airplanes outside of the original applicability of AD 2017-15-01. This proposed AD would retain the requirements of AD 2017-15-01, expand the applicability to include those other airplanes, and add a new requirement for certain airplanes to identify and replace the affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
