Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2009-06-
06 for all Airbus Model A310 and A300-600 series airplanes. AD 2009-06-
06 currently requires revising the Airworthiness Limitations Section of 
the Instructions for Continued Airworthiness to incorporate new 
limitations and maintenance tasks for aging systems maintenance. Since 
we issued AD 2009-06-06, we have determined that more restrictive 
maintenance requirements and airworthiness limitations are necessary. 
This proposed AD would require revising the maintenance or inspection 
program to incorporate new maintenance requirements and airworthiness 
limitations. We are proposing this AD to prevent reduced structural 
integrity and reduced control of these airplanes due to the failure of 
system components.

DATES: We must receive comments on this proposed AD by May 12, 2014.

Discussion

    On February 27, 2009, we issued AD 2009-06-06, Amendment 39-15842 
(74 FR 12228, March 24, 2009). AD 2009-06-06 requires actions intended 
to address an unsafe condition for all Airbus Model A310 and A300-600 
series airplanes.
    Since we issued AD 2009-06-06, Amendment 39-15842 (74 FR 12228, 
March 24, 2009), we have determined that more restrictive maintenance 
requirements and airworthiness limitations are necessary.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2013-0075, dated March 20, 2013 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for Airbus Model A310-
203, -204, -221, -222, -304, -322, -324, and -325 airplanes; A300 B4-
601, B4-603, B4-620, and B4-622 airplanes; A300 B4-605R and B4-622R 
airplanes; A300 F4-605R and F4-622R, and A300 C4-605R Variant F 
airplanes. The MCAI states:

    The airworthiness limitations for Airbus aeroplanes are 
currently published in Airworthiness Limitations Section (ALS) 
documents.
    The mandatory instructions and airworthiness limitations 
applicable to the Aging Systems Maintenance (ASM) are specified in 
Airbus A310 or A300-600 ALS Part 4 documents, which are approved by 
the European Aviation Safety Agency (EASA). EASA AD 2007-0092 
[http://ad.easa.europa.eu/blob/easa_ad_2007_0092.pdf/AD_2007-0092] [which corresponds to FAA AD 2009-06-06, Amendment 39-15842] 
was issued to require compliance to the requirements as specified in 
these documents.
    The revision 02 of Airbus A310 and Airbus A300-600 ALS Part 4 
documents introduces more restrictive maintenance requirements and/
or airworthiness limitations. Failure to comply with the 
instructions of ALS Part 4 could result in an unsafe condition.
    For the reasons described above, this new AD retains the 
requirements of EASA AD

[[Page 17452]]

2007-0092, which is superseded, and requires the implementation of 
the new or more restrictive maintenance requirements and/or 
airworthiness limitations as specified in Airbus A310 ALS Part 4, 
Revision 02, or Airbus A300-600 ALS Parr 4, Revision 02, as 
applicable to aeroplane type/model.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2014-
0173.

Relevant Service Information

    Airbus has issued A310 Airworthiness Limitations Section (ALS) Part 
4--Ageing Systems Maintenance, Revision 02, dated November 30, 2012 
(for Model A310 series airplanes); and A300-600 ALS Part 4--Ageing 
Systems Maintenance, Revision 02, dated April 18, 2012 (for Model A300-
600 series 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 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

    We estimate that this proposed AD affects 156 airplanes of U.S. 
registry.
    The ALS revision required by AD 2009-06-06, Amendment 39-15842 (74 
FR 12228, March 24, 2009), and retained in this proposed AD takes about 
1 work-hour per product, at an average labor rate of $85 per work-hour. 
Based on these figures, the estimated cost of the actions that were 
required by AD 2009-06-06 is $85 per product.
    We also estimate that it would take about 1 work-hour 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 this proposed AD on U.S. operators to be $13,260, or $85 
per product.

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.
