AD 2026-15-02: The Boeing Company Airplanes

What the FAA requires

The FAA is superseding Airworthiness Directive (AD) 2024-19- 14, which applied to certain The Boeing Company Model 777-200, 777- 200LR, 777-300ER, and 777F series airplanes. AD 2024-19-14 required repetitive inspections and bond resistance measurement of the bonding jumpers on the first fuel feed tube installed immediately forward of the wing front spar at the left and right main fuel tank penetrations and applicable corrective actions. This AD was prompted by a determination that additional inspections are required to address the unsafe condition. This AD requires repetitive detailed inspections (DETs), repetitive bond resistance measurement, and applicable on- condition actions. This AD also expands the applicability and requires revising the existing maintenance or inspection program, as applicable, to incorporate a certain airworthiness limitation. The FAA is issuing this AD to address the unsafe condition on these products.

Applicability

Boeing requested that the FAA revise the applicability of the proposed AD by adding a reference to Boeing Alert Requirements Bulletin 777-28A0098 RB, dated August 15, 2025 (Boeing Alert Requirements Bulletin 777-28A0098 RB). Boeing stated Boeing Alert Requirements Bulletin 777-28A0097 RB, dated August 14, 2025 (Boeing Alert Requirements Bulletin 777-28A0097 RB), and Boeing Alert Requirements Bulletin 777-28A0098 RB apply to all Boeing Model 777 series airplanes and therefore should both be referenced. The FAA notes that the serial numbers listed in the effectivity of Boeing Alert Requirements Bulletin 777-28A0097 RB and Boeing Alert Requirements Bulletin 777-28A0098 RB each identify all Mode
