Airworthiness Directive 2026-04-10
recurringAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
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.
Which aircraft AD 2026-04-10 applies to
Applies to airplanes as identified in Boeing Alert Requirements Bulletin 767-23A0351 RB, dated January 23, 2025.
Whether AD 2026-04-10 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
