Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A330-200 freighter series airplanes; Model A330-200 and -
300 series airplanes; and Model A340-200 and -300 series airplanes. 
This proposed AD was prompted by reports of ram air turbine (RAT) pump 
failure. This proposed AD would require 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 
proposing 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: We must receive comments on this proposed AD by August 27, 2012.

ADDRESSES: You may send comments by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2011-0197, dated October 10, 2011 (referred to 
after this as ``the MCAI''), to correct an unsafe condition for the 
specified products. The 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 [EASA] 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.

Relevant Service Information

    Airbus has issued Mandatory Service Bulletin A330-29-3117, dated 
July 19, 2011 (for Model A330 airplanes); and Mandatory Service 
Bulletin A340-29-4090, dated July 19, 2011 (for Model A340 airplanes). 
The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed 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

[[Page 40831]]

of the unsafe condition described in the MCAI and service information 
referenced above. We are proposing this AD because we evaluated all 
pertinent information and determined an unsafe condition exists and is 
likely to exist or develop on other products of the same type design.

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 59 products of U.S. registry. We also estimate that 
it would take about 4 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Based on these figures, we estimate the cost of the proposed 
AD on 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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 proposed AD and placed it in the AD docket.
