Airworthiness Directive · Amendment 39-17893 · Fuel
Airbus Airplanes
Superseded. A later AD replaced this one: AD 2017-19-12. Comply with the one in force.
This AD applies to the Airbus airplanes specified in paragraphs (c)(1), (c)(2), (c)(3), (c)(4), (c)(5), and (c)(6) of this AD; certificated in any category; all serial numbers.
(1) Model A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, and B4-203 airplanes.
(2) Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes.
(3) Model A300 B4-605R and B4-622R airplanes.
(4) Model A300 F4-605R and F4-622R airplanes.
(5) Model A300 C4-605R Variant F airplanes.
(6) 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 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 Model A310 series airplanes. This AD was prompted by reports of failures of the right inner tank fuel pump. This AD requires repetitive functional tests of the circuit breakers for the fuel pump power supply, and replacement of certain circuit breakers. We are issuing this AD to detect and correct failure of the circuit breakers for the fuel pump power supply, which could result in a fuel pump overheating, leading to a fuel tank explosion.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
(1) Within 6 months or 500 flight hours after the effective date of this AD, 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.
(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 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.
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.
