Unsafe condition
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. The FAA is issuing this AD to prevent corrosion damage of the SATCOM high gain antenna adapter plates, which could result in parts departing the airplane (PDA). A PDA event of the SATCOM high gain antenna system could damage the primary flight control surfaces which may result in loss of continued safe flight and landing of the airplane.
Affected ADs
None.
