## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 777-200, -200LR, -300, and -300ER series airplanes. This proposed AD was prompted by a report of corrosion found on a satellite communications (SATCOM) high gain antenna adapter plate. This proposed AD would require repetitive inspections for corrosion of the SATCOM high gain antenna adapter plate and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
