Airworthiness Directive · Amendment 39-19042 · Fuel
Airbus Airplanes
This AD applies to the Airbus airplanes, certificated in any category, identified in paragraphs (c)(1) through (c)(6) of this AD, all manufacturer serial numbers.
(1) Airbus Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes.
(2) Airbus Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes.
(3) Airbus Model A300 B4-605R and B4-622R airplanes.
(4) Airbus Model A300 C4-605R Variant F airplanes.
(5) Airbus Model A300 F4-605R and F4-622R airplanes.
(6) Airbus Model A310-203, -204, -221, -222, -304, -322, -324, and -325 airplanes.
We are superseding Airworthiness Directive (AD) 2014-13-17, which applied to all Airbus Model A300 series airplanes; 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. AD 2014-13-17 required repetitive functional tests of the circuit breakers for the fuel pump power supply, and replacement of certain circuit breakers. This new AD requires installation of fuel pumps having a new standard, which terminates the repetitive functional tests. This AD was prompted by our determination that installation of a newly developed fuel pump standard will better address the unsafe condition. We are issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2014-13-17, with a new terminating action.
(1) Within 6 months or 500 flight hours after August 19, 2014 (the effective date of AD 2014-13-17), whichever occurs first: Do a functional test of the circuit breakers for the fuel pump power supply, as identified in paragraphs (g)(1)(i), (g)(1)(ii), and (g)(1)(iii) of this AD, as applicable, in accordance with Airbus Alert Operators Transmission A28W002-13, dated July 23, 2013. Repeat the functional test thereafter at intervals not to exceed 6 months or 500 flight hours, whichever occurs first, until the fuel pump installation required by paragraph (h) of this AD is accomplished.
(i) For Airbus Model A300 B2-1A, B2-1C, B2K-3C, and B2-203 airplanes: Inner and outer pump, No. 1 and No. 2, left-hand (LH) side and right-hand (RH) side.
(ii) For Airbus Model A300 B4-2C, B4-103, B4-203, B4-601, B4-603, B4-620, and B4-622 airplanes; and Model A310-203, -204, -221, and -222 airplanes:
(A) Inner and outer pump, No. 1 and No. 2, LH and RH; and
(B) Center pump, LH and RH.
(iii) For Airbus Model A300 B4-605R, B4-622R, F4-605R, F4-622R, and C4-605R Variant F airplanes; and Model A310-304, -322, -324, and -325 airplanes:
(A) Inner and outer pump, No. 1 and No. 2, LH and RH;
(B) Center pump, LH and RH; and
(C) Trim tank pump No. 1 and No. 2.
(2) If, during any functional test required by paragraph (g)(1) of this AD, any circuit breaker fails any functional test, or any circuit breaker is found to be stuck closed, before further flight, replace the affected circuit breaker with a serviceable part, in accordance with Airbus Alert Operators Transmission A28W002-13, dated July 23, 2013.
(3) The replacement of one or more circuit breakers as required by paragraph (g)(2) of this AD does not terminate the repetitive functional tests required by paragraph (g)(1) of this AD.
Within 72 months after the effective date of this AD: Install a fuel pump having a new standard at each applicable location on the airplane, in accordance with the Accomplishment Instructions of the applicable service information specified in paragraph (h)(1), (h)(2), or (h)(3) of this AD. Accomplishment of the installation of fuel pumps having the new standard terminates the requirement for the repetitive functional tests required by paragraph (g)(1) of this AD.
