The FAA proposes to supersede Airworthiness Directive (AD) 2018-14-02, which applies to certain The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. AD 2018-14-02 requires an inspection for foam insulation on the dripshield above the overhead panel support structure and replacement if necessary. For certain airplanes, AD 2018-14-02 also requires replacement of foam insulation on the overhead panel support structure. Since the FAA issued AD 2018- 14-02, additional areas of Boeing Material Specification (BMS) 8-39 flexible urethane foam were found on the overhead panel support structure. This proposed AD would continue to require the actions in AD 2018-14-02, and, for certain airplanes, this proposed AD would require an inspection of the foam insulation on the overhead panel support structure, and replacement if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
