Airworthiness Directives; The Boeing Company Airplanes

The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 767-200, 767-300, 767-300F, and 767- 400ER airplanes. This AD was prompted by a heavy maintenance check that found corrosion damage on a Model 767 satellite communications (SATCOM) high gain antenna adapter plate. This AD requires repetitive detailed inspections (DET) of the SATCOM high gain antenna adapter plate for corrosion and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.
