Airworthiness Directive · Amendment 39-18676 · Fuel
Airbus Airplanes
This AD applies to Airbus Model A330-223F and -243F airplanes; Model A330-201, -202, -203, -223, and -243 airplanes; Model A330-301, -302, -303, -321, -322, -323, -341, -342, and -343 airplanes; Model A340-211, -212, and -213 airplanes; Model A340-311, -312, and -313 airplanes; Model A340-541 and A340-642 airplanes; certificated in any category; all manufacturer serial numbers.
We are adopting a new airworthiness directive (AD) for all Airbus Model A330-200 Freighter, -200, and -300 series airplanes; and Airbus Model A340-200, -300, -500, and -600 series airplanes. This AD was prompted by reports of fuel leaking through fuel pump electrical connectors and of fuel pump electrical connector damage caused by the build-up of moisture behind the electrical connectors. This AD requires an inspection of the fuel pumps to identify their part numbers and replacement of affected pumps. We are issuing this AD to prevent a potential ignition source and a fuel leak through damaged fuel pump electrical connectors, which creates a flammability risk in an area adjacent to the fuel tank.
Within 48 months after the effective date of this AD, inspect each fuel pump to identify the part number, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-28-3127, Revision 02, dated April 14, 2016; Airbus Service Bulletin A340-28-4138, Revision 01, dated September 24, 2015; or Airbus Service Bulletin A340-28-5060, Revision 01, dated September 24, 2015; as applicable to airplane model. A review of airplane delivery or maintenance records is acceptable in lieu of this inspection if the part number of the fuel pump can be conclusively determined from that review.
If, during the inspection required by paragraph (g) of this AD, it is determined that any affected fuel pump is installed: Within the compliance time specified in paragraph (h)(1) or (h)(2) of this AD, depending on the configuration of the affected fuel pumps installed, replace each affected fuel pump with a serviceable fuel pump, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A330-28-3127, Revision 02, dated April 14, 2016; Airbus Service Bulletin A340-28-4138, Revision 01, dated September 24, 2015; or Airbus Service Bulletin A340-28-5060, Revision 01, dated September 24, 2015; as applicable to airplane model.
(1) For airplanes with fuel pumps that have a part number or combination of part numbers that are specified in paragraphs (h)(1)(i) through (h)(1)(vi) of this AD: Do the replacement within 72 months after the effective date of this AD.
(i) All installed fuel pumps have P/N 568-1-28300-001.
(ii) All installed fuel pumps have P/N 568-1-28300-002.
(iii) Installed fuel pumps have a combination of P/Ns 568-1-28300-001 and 568-1-28300-002.
(iv) Installed fuel pumps have a combination of P/Ns 568-1-28300-001 and 568-1-28300-101.
(v) Installed fuel pumps have a combination of P/Ns 568-1-28300-002 and 568-1-28300-101.
(vi) Installed fuel pumps have a combination of P/Ns 568-1-28300-001, 568-1-28300-002, and 568-1-28300-101.
(2) For airplanes with fuel pumps that have a part number or combination of part numbers that are specified in paragraphs (h)(2)(i) through (h)(2)(iii) of this AD: Do the replacement within 96 months after the effective date of this AD.
(i) All installed fuel pumps have P/N 568-1-28300-100.
(ii) All installed fuel pumps have P/N 568-1-28300-101.
(iii) Installed fuel pumps have a combination of P/Ns 568-1-28300-100 and 568-1-28300-101.
(1) For the purpose of this AD, an “affected fuel pump” is defined as any pump having P/N 568-1-28300-001, 568-1-28300-002, 568-1-28300-100, or 568-1-28300-101.
(2) For the purpose of this AD, a “serviceable fuel pump” is a pump having a part number not listed in paragraph (i)(1) of this AD.
Although Airbus Service Bulletin A330-28-3127, Revision 02, dated April 14, 2016; Airbus Service Bulletin A340-28-4138, Revision 01, dated September 24, 2015; and Airbus Service Bulletin A340-28-5060, Revision 01, dated September 24, 2015; specify submitting certain information to the manufacturer, and specifies that action as “RC” (Required for Compliance), this AD does not include that requirement.
