Airworthiness Directive · Amendment 39-17340 · Fuel
Airbus Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) All Airbus Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes; Model A300 B4-605R and B4-622R airplanes; Model A300 F4-605R and F4-622R airplanes; and Model A300 C4-605R Variant F airplanes.
(2) All Airbus Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes.
We are adopting a new airworthiness directive (AD) for all Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R Variant F airplanes (collectively called Model A300- 600 series airplanes); and Airbus Model A310 series airplanes. This AD was prompted by fuel system reviews conducted by the European Aviation Safety Agency (EASA). This AD requires modifying the electrical control circuits of the inner, center, and trim tank pumps, as applicable. We are issuing this AD to reduce the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in fuel tank explosions and consequent loss of the airplane.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 48 months after the effective date of this AD, accomplish the actions specified in paragraph (g)(1) or (g)(2) of this AD, as applicable.
(1) For Model A310 series airplanes: Modify the electrical control circuits of the inner, center, and trim tank pumps, as applicable, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A310-28-2170, dated February 28, 2012.
(2) For Model A300-600 airplanes: Modify the electrical control circuits of the inner, center, and trim tank pumps, as applicable, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-28-6104, dated February 28, 2012.
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.
