## Summary

The FAA proposes to supersede Airworthiness Directive (AD) 2017-15-04, which applies to certain The Boeing Company Model 787-8 and 787-9 airplanes. AD 2017-15-04 requires replacement of affected electromechanical actuators (EMAs). Since AD 2017-15-04 was issued, the FAA has determined that discrepant EMAs may have been installed on airplanes outside the original applicability of AD 2017-15-04. This proposed AD would retain the requirements of AD 2017-15-04, expand the applicability to include all The Boeing Company Model 787 series airplanes, and add a new requirement to identify, for certain airplanes, the part number of EMAs and replace affected EMAs. The FAA is proposing this AD to address the unsafe condition on these products.
