SUPPLEMENTARY INFORMATION: 

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2017-0041, dated February 24, 2017; corrected 
February 28, 2017 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Airbus Model A330-243, -243F, -341, -342, and -343 
airplanes. The MCAI states:

    Following introduction in-service of Airbus modification (mod) 
205242, a new hydraulic pressure tube assembly Part Number (P/N) 
AE711121-18 was installed, one on each engine, with an integral 
ripple damper. It was determined that, at a relatively low number of 
cycles, cracks can develop on the ripple damper weld of this new 
hydraulic pressure tube, which could lead to hydraulic leakage and 
consequent loss of the green hydraulic system. Recently, there has 
been a high rate of failure of the affected dampers that, if 
continued, may exceed the overall safety objective of the certified 
design.
    This condition, if not corrected, could, in combination with 
other system failures, result in reduced control of the aeroplane.
    Prompted by these findings, Airbus issued Alert Operators 
Transmission (AOT) A71L012-16 Revision 01, to provide instructions 
to replace the hydraulic pressure tube assembly P/N AE711121-18 with 
an improved assembly, P/N AE711121-18 Rev A, equipped with a double-
welded ripple damper.
    For the reasons described above, this [EASA] AD requires 
[inspection for and] replacement of each affected hydraulic pressure 
tube assembly with a [serviceable] tube assembly having the double 
welded ripple damper installed. This [EASA] AD also requires 
implementation of a life limit

[[Page 15986]]

on the new part [i.e., repetitive replacements of serviceable 
hydraulic pressure tube assemblies]. This [EASA] AD is considered as 
interim measure and further AD action may follow.
    This [EASA] AD is republished to correct the TCDS number and add 
a previous manufacturer name.

0245.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Alert Operators Transmission (AOT) A71L012-16, 
Revision 01, dated February 24, 2017. The service information describes 
procedures for replacing hydraulic pressure tube assembly, part number 
(P/N) AE711121-18, and hydraulic pressure tube assembly, P/N AE711121-
18 Rev A. This service information is reasonably available because the 
interested parties have access to it through their normal course of 
business or by the means identified in the ADDRESSES section.

FAA's Determination and Requirements of This AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of these 
same type design.

Difference Between This AD and the MCAI

    The MCAI mandates replacement of the hydraulic pressure tube 
assembly, using Airbus AOT A71L012-16, Revision 01, dated February 24, 
2017. However, Airbus AOT A71L012-16, Revision 01, dated February 24, 
2017, also specifies to first inspect or do a records review to 
determine the part number of the hydraulic pressure tube assembly. 
Therefore, paragraph (i) of this AD requires the inspection or records 
review.
    The MCAI includes a compliance time of ``within 5 months'' for the 
replacement of the affected part. We have determined that a compliance 
time of ``within 4 months'' is necessary to adequately address the 
identified unsafe condition. We have included the 4-month compliance 
time in paragraphs (j), (l), and (m) of this AD.
    We have coordinated these differences with EASA.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
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 and because of reports of failure of the 
ripple damper of the hydraulic pressure tube assembly. This condition 
could, in combination with other system failures, result in reduced 
control of the airplane. Therefore, we determined that notice and 
opportunity for public comment before issuing this AD are impracticable 
and that good cause exists for making this amendment effective in fewer 
than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2017-0245; Directorate 
Identifier 2017-NM-023-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD based on 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 53 airplanes of U.S. registry.
    We also estimate that it will take about 5 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $20,000 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $1,082,525, or $20,425 per product.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.

Regulatory Findings

    We determined that this AD will not have federalism implications 
under Executive Order 13132. This AD will not have a substantial direct 
effect on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.
    For the reasons discussed above, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

2017-07-05 Airbus: Amendment 39-18841; Docket No. FAA-2017-0245; 
Directorate Identifier 2017-NM-023-AD.

(a) Effective Date

    This AD becomes effective April 17, 2017.

(b) Affected ADs

    None.

(c) Applicability

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

(d) Subject

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

(e) Reason

    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.

(f) Compliance

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

(g) Definition of Affected Part

    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.

(h) Definition of Serviceable Part

    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.

(i) Identification of Affected Parts

    Within 15 days after 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.

(j) Replacement of Affected Parts

    Within the compliance time specified in table 1 to paragraph (j) 
of this AD, as applicable, or within 4 months after 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.
