Summary
We propose to supersede Airworthiness Directive (AD) 2017-01- 02, which applies to certain The Boeing Company Model 787-8 and 787-9 airplanes. AD 2017-01-02 requires an inspection for discrepant inboard and outboard trailing edge flap rotary actuators. Since we issued AD 2017-01-02, we have determined that it is necessary to revise the applicability to include additional airplanes, and to reduce the number of affected actuators. This proposed AD would continue to require an inspection of the inboard and outboard trailing edge flap rotary actuator for any discrepant rotary actuator, and corrective actions if necessary. We are proposing this AD to address the unsafe condition on these products.
