14 CFR Part 39

[Docket No. FAA-2011-0650; Directorate Identifier 2010-NM-257-AD; 
Amendment 39-16846; AD 2011-22-04]
RIN 2120-AA64

 
Airworthiness Directives; Airbus Model A310 Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for the 
products listed above. This AD results from mandatory continuing 
airworthiness information (MCAI) originated by an aviation authority of 
another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as:

    [T]he FAA has published SFAR 88 (Special Federal Aviation 
Regulation 88).
    In their letters referenced 04/00/02/07/01-L296, dated March 
4th, 2002, and 04/00/02/07/03-L024, dated February 3rd, 2003, the 
[Joint Aviation Authorities] JAA recommended the application of a 
similar regulation to the National Aviation Authorities (NAA).
    Under this regulation, all holders of type certificates for 
passenger transport aircraft with either a passenger capacity of 30 
or more, or a payload capacity of 3,402 kg (7,500 lb) or more which 
have received their certification since January 1st, 1958, are 
required to conduct a design review against explosion risks.
* * * * *
The unsafe condition is insufficient electrical bonding of the over-
wing refueling cap adapter, which could result in a possible fuel 
ignition source in the fuel tanks. We are issuing this AD to require 
actions to correct the unsafe condition on these products.

DATES: This AD becomes effective November 29, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 29, 
2011.

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 5, 2011 (76 FR 
39035). That NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    [T]he FAA has published SFAR 88 (Special Federal Aviation 
Regulation 88).
    In their letters referenced 04/00/02/07/01-L296, dated March 
4th, 2002, and 04/00/02/07/03-L024, dated February 3rd, 2003, the 
JAA recommended the application of a similar regulation to the 
National Aviation Authorities (NAA).
    Under this regulation, all holders of type certificates for 
passenger transport aircraft with either a passenger capacity of 30 
or more, or a payload capacity of 3,402 kg (7,500 lb) or more which 
have received their certification since January 1st, 1958, are 
required to conduct a design review against explosion risks.
* * * * *
    * * * [This EASA AD] requires the additional work introduced by 
Airbus SB A310-28-2142 at revision 3.

The unsafe condition is insufficient electrical bonding of the over-
wing refueling cap adapter, which could result in a possible fuel 
ignition source in the fuel tanks. 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 (76 FR 39035, July 5, 
2011) or on the determination of the cost to the public.

Revision to Airbus Mandatory Service Bulletin A310-28-2142

    Airbus has issued Mandatory Service Bulletin A310-28-2142, Revision 
04, dated November 30, 2010. No additional work is included in this 
revision for airplanes modified by any previous issue of this document. 
We have changed paragraphs (g), (g)(1), (g)(2), (h), (k), and sub-
paragraph (1) of Note 1 of this AD to refer to Airbus Service Bulletin 
A310-28-2142, Revision 04, dated November 30, 2010, and added paragraph 
(i) to this AD to give credit for actions accomplished in accordance 
with Airbus Mandatory Service Bulletin A310-28-2142, Revision 03, dated 
November 18, 2009.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting the AD with the changes described 
previously. We determined that these changes will not increase the 
economic burden on any operator or increase the scope of the AD.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a NOTE within the AD.

Costs of Compliance

    We estimate that this AD will affect 66 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. Required parts will cost about $200 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 $35,640, or $540 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 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 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); and
    3. 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 (76 FR 39035, July 5, 2011), 
the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office

FAA AD Differences

    Note 1: This AD differs from the MCAI and/or service information 
as follows:
    (1) Airbus Mandatory Service Bulletin A310-28-2142, Revision 04, 
dated November 30, 2010, specifies that if any resistance 
measurement is more than 10 mohm, corrective actions must be done. 
This AD specifies that if any resistance measurement is 10 mohm or 
greater, corrective actions must be done.
    (2) Paragraphs (1), (2), and (4) of European Aviation Safety 
Agency (EASA) Airworthiness Directive 2010-0199, dated September 30, 
2010, include actions that are not required in this AD. These
