Models named: A300 B2-1A, B2-1C, B2K-3C, B2-203, B4-2C, B4-103, B4-203, A300 B4-601, B4-603, B4-620. Read the applicability below — it usually turns on serial or part numbers too.

Applicability*9

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.

Compliance

Comply with this AD within the compliance times specified, unless already done.

Required actions

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.

Unsafe condition

This AD was prompted by reports of failures of the right inner tank fuel pump. We are issuing this AD to prevent a fuel pump from overheating, which could result in a fuel tank explosion and consequent loss of the airplane.

Affected ADs

This AD replaces 2014-13-17, Amendment 39-17893 (79 FR 41098, July 15, 2014) (“AD 2014-13-17”).
