Airworthiness Directives; Airbus Model A300 B4-600R and A300 F4-600R Series Airplanes

Riepilogo

This amendment supersedes an existing airworthiness directive (AD), applicable to Airbus Model A300 B4-600R and A300 F4-600R series airplanes, that currently requires a one-time detailed inspection for damage of the center tank fuel pumps and fuel pump canisters, and replacement of damaged fuel pumps and fuel pump canisters with new or serviceable parts. That AD also requires repetitive detailed inspections of the fuel pumps and repetitive eddy current inspections of the fuel pump canisters, and replacement of damaged fuel pumps and fuel pump canisters with new or serviceable parts. This amendment mandates modification of the canisters of the center tank fuel pumps, which would terminate the repetitive inspections required by the existing AD. The actions specified by this AD are intended to prevent damage to the fuel pump and fuel pump canister, which could result in loss of flame trap capability and could provide a fuel ignition source in the center fuel tank. This action is intended to address the identified unsafe condition.
