14 CFR Part 39

[Docket No. FAA-2012-0596; Directorate Identifier 2011-NM-245-AD; 
Amendment 39-17236; AD 2012-21-20]
RIN 2120-AA64


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 certain 
Airbus Model A330-200 freighter series airplanes, Model A330-200 and -
300 series airplanes, and Model A340-200, -300, -500, and -600 series 
airplanes. This AD was prompted by reports of the ram air turbine (RAT) 
not deploying when tested. This AD requires identification of the 
supplier, part number, and serial number of the installed RAT actuator, 
and re-identification of the actuator and RAT, or replacement of the 
RAT actuator with a serviceable unit and re-identification of the RAT, 
if necessary. We are issuing this AD to prevent non-deployment of the 
RAT, which if occurred following a total engine flame-out, or during a 
total loss of normal electrical power generation, could result 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 http://www.regulations.gov 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 June 18, 2012 (77 FR 
36209). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    During a production test flight, a Ram Air Turbine (RAT) did not 
deploy when tested. An investigation, conducted by the RAT 
manufacturer Hamilton Sundstrand (HS) and Arkwin Industries, 
revealed that the RAT did not deploy due to insufficient stroke 
inside one of the actuator deployment solenoids.
    This condition, if occurring following a total engine flame out, 
or during a total loss of normal electrical power generation, could 
possibly result in reduced control of the aeroplane.
    For the reasons described above, this [European Aviation Safety 
Agency] AD requires the modification of the affected RAT actuator 
deployment mechanism, or replacement of the RAT actuator with a 
modified unit.

The required actions include identification of the supplier, part 
number, and serial number of the installed RAT actuator, and re-
identification of the actuator and RAT, or replacement of the RAT 
actuator with a serviceable unit and re-identification of the RAT, if 
necessary. 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 36209, June 18, 
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 and re-identification of the sub-paragraphs of 
paragraphs (g) and (h) of this final rule. We have determined that 
these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 36209, June 18, 2012) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 36209, June 18, 2012).

Costs of Compliance

    We estimate that this AD will affect 56 products of U.S. registry. 
We also estimate that it will take about 14 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 $0 per product. 
Where the service information lists required parts costs that are 
covered under warranty, we have assumed that there will be no charge 
for these parts. As we do not control warranty coverage for affected 
parties, some parties may incur costs higher than estimated here. Based 
on these figures, we estimate the cost of this AD to the U.S. operators 
to be $66,640, or $1,190 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 13 work-hours and require parts costing $0, for a cost of 
$1,105 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);

[[Page 65800]]

    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 http://www.regulations.gov; 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 36209, June 18, 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.
