## Summary

The FAA proposes to supersede an existing airworthiness directive (AD) for certain Boeing Model 747, 757, 767, and 777 series airplanes. That AD currently requires modifying certain drip shields located on the flight deck, and follow-on actions. This proposed AD would remove certain airplanes that are included in the applicability statement of the existing AD, and would require modifying additional drip shields on the flight deck of certain other airplanes. This proposed AD is prompted by a determination that certain airplanes have drip shields that are not adequately resistant to fire. We are proposing this AD to prevent potential ignition of the moisture barrier cover of the drip shield, which could propagate a small fire that results from an electrical arc, leading to a larger fire.
