summary: 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.
