14 CFR Part 39

[Docket No. FAA-2012-0719; Directorate Identifier 2011-NM-240-AD; 
Amendment 39-17235; AD 2012-21-19]

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A330-200 freighter series airplanes; Model A330-200 and -
300

[[Page 65813]]

series airplanes; and Model A340-200 and -300 series airplanes. This AD 
was prompted by reports of ram air turbine (RAT) pump failure. This AD 
requires inspecting the RAT pump anti-stall valve for correct setting, 
re-identifying the RAT pump, performing a functional ground test of the 
RAT, and replacing the RAT pump or the RAT assembly with a serviceable 
part if necessary. We are issuing this AD to detect and correct 
malfunction of the RAT pump, which could lead to in-flight loss of the 
RAT-pump pressurization, possibly resulting in reduced control of the 
airplane.

DATES: This AD becomes effective December 5, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 5, 
2012.

ADDRESSES: You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on July 11, 2012 (77 FR 
40830). That NPRM proposed to correct an unsafe condition for the 
specified products. The Mandatory Continuing Airworthiness Information 
(MCAI) states:

    During a test flight before delivery from production, an A330 
aeroplane experienced a RAT [ram air turbine] pump failure, as a 
result of which, the green hydraulic system could not be fully 
pressurized.
    Investigations concluded that this malfunction was due to poor 
installation of the anti-stall valve sleeve, causing a shift in the 
anti-stall speed setting and leading to an inability of the 
hydraulic pump Part Number (P/N) 5909522 to provide enough hydraulic 
pressure.
    This condition, if not detected and corrected, could lead to the 
in-flight loss of the RAT-Pump pressurization which, in case of a 
total engine flame out, could have consequences for the hydraulic 
circuits, possibly resulting in reduced control of the aeroplane. 
A340-500/-600 series aeroplanes are not affected by this issue 
because they are fitted with a different hydraulic pump P/N.
    For the reasons described above, this [European Aviation Safety 
Agency] AD requires a check to ensure correct setting of the RAT 
anti-stall valve in the pump housing, followed by a RAT functional 
ground test, and accomplishment of the applicable corrective 
actions, depending on findings.

Corrective actions include replacing the RAT pump or the RAT assembly 
with a serviceable part. Required actions include reporting the 
findings of the inspection. You may obtain further information by 
examining the MCAI in the AD docket.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (77 FR 40830, July 11, 
2012) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD as proposed--except for 
minor editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (77 FR 40830, July 11, 2012) for correcting the unsafe condition; 
and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 40830, July 11, 2012).

Costs of Compliance

    We estimate that this AD will affect 59 products of U.S. registry. 
We also estimate that it will take about 4 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD to the U.S. operators to be $20,060, or $340 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 7 work-hours and require parts costing up to $405,143, for a 
cost of up to $405,738 per product. We have no way of determining the 
number of products that may need these actions.

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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.

Examining the AD Docket

    You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM (77 FR 40830, July 11, 2012), 
the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office 
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will 
be available in the AD docket shortly after receipt.
