Airbus Model A300 B4-600 and A300 C4-600 Series Airplanes
Superseded. A later AD replaced this one: AD 2006-12-05. Comply with the one in force.
Model A300 B4-601, A300 B4-603, A300 B4-620, and A300 C4-605 Variant F series airplanes; certificated in any category; except those airplanes equipped with a fuel trim tank system (Airbus Modification 4801).
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300 B4-600 and A300 C4-600 series airplanes, that requires a one-time inspection to detect damage of the pump diffuser guide slots (bayonet) of the center tank fuel pumps, the pump diffuser housings, and the pump canisters; repetitive inspections to detect damage of the fuel pumps and the fuel pump canisters; and corrective action, if necessary. This action is necessary to detect and correct damage of the center tank fuel pumps and fuel pump canisters, which could result in separation of a pump from its electrical motor housing, loss of flame trap capability, and a possible fuel ignition source in the center fuel tank. This action is intended to address the identified unsafe condition.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
