- What it does
The FAA is superseding Airworthiness Directive (AD) 2023-07- 09, which applied to certain The Boeing Company Model 747-400 and -8 series airplanes. AD 2023-07-09 required inspecting for wear of the transfer pump housing inlet check valves and transfer pump motor impeller inlet adapters for the horizontal stabilizer fuel tank and doing corrective actions, if necessary, and limited the installation of affected parts. This AD was prompted by the manufacturer developing further action to address the unsafe condition. This AD requires repetitive inspections for damage of the transfer pump housing inlet check valves and transfer pump motor impeller inlet adapters for the horizontal stabilizer fuel tank and applicable on-condition actions. This AD also limits the installation of affected parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
