AD 2017-07-03

This AD is effective April 17, 2017.

None.

This AD applies to Airbus Model A330-243, -243F, -341, -342, and -343 airplanes, certificated in any category, all manufacturer serial numbers.

Air Transport Association (ATA) of America Code 71, Powerplant.

This AD was prompted by a determination that cracks can develop on the ripple damper of the hydraulic pressure tube assembly, which could lead to hydraulic leakage and consequent loss of the green hydraulic system. This AD was also prompted by reports of failure of the ripple damper of the hydraulic pressure tube assembly. We are issuing this AD to prevent cracking and failure of the ripple damper of the hydraulic pressure tube assembly, which could, in combination with other system failures, result in reduced control of the airplane.

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

For the purpose of this AD, a hydraulic pressure tube assembly, part number (P/N) AE711121-18, as introduced by Airbus mod 205242, is hereafter referred to as an “affected part” in this AD.

For the purpose of this AD, a “serviceable part” is a hydraulic pressure tube assembly (which has a double-welded ripple damper installed), P/N AE711121-18 Rev A, that has accumulated fewer than 800 total flight cycles since first installation on an airplane. The hydraulic pressure tube assembly, P/N AE711121-18 Rev A, is introduced by Airbus mod 206979 on the production line.

Within 15 days after April 17, 2017 (the effective date of this AD), inspect to determine the part number of the hydraulic pressure tube assembly that is installed on each engine. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the hydraulic pressure tube assembly can be conclusively determined from that review.

Within the compliance time specified in table 1 to paragraph (j) of this AD, as applicable, or within 4 months after April 17, 2017 (the effective date of this AD), whichever occurs first, replace each affected part (see paragraph (g) of this AD) with a serviceable part (see paragraph (h) of this AD), in accordance with the instructions of Airbus Alert Operators Transmission (AOT) A71L012-16, Revision 01, dated February 24, 2017.

Before a serviceable part (see paragraph (h) of this AD) exceeds 800 total flight cycles since first installation on an airplane, replace it with a serviceable part, in accordance with the instructions of Airbus AOT A71L012-16, Revision 01, dated February 24, 2017.

As of April 17, 2017 (the effective date of this AD), except as required by paragraph (m) of this AD, it is allowed to install on any airplane a replacement engine having an affected part (see paragraph (g) of this AD) installed, provided that, before that affected part exceeds 800 total flight cycles since first installation on an airplane, or within 4 months after April 17, 2017 (the effective date of this AD), whichever occurs first, the part is replaced with a serviceable part (see paragraph (h) of this AD), in accordance with the instructions of Airbus AOT A71L012-16, Revision 01, dated February 24, 2017.

As of 4 months after April 17, 2017 (the effective date of this AD): Do not install on any airplane an affected part (see paragraph (g) of this AD), or an engine having an affected part installed.

This paragraph provides credit for actions required by paragraph (j) of this AD, if those actions were performed before April 17, 2017 (the effective date of this AD) using Airbus AOT A71L012-16, dated December 22, 2016.
