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 that would supersede two existing ADs. 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:

    DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
France AD 1992-106-132(B) * * * has been issued in order to mandate 
a set of inspections/modifications which address JAR/FAR [Joint 
Aviation Regulation/Federal Aviation Regulation] 25-571 requirements 
related to damage-tolerance and fatigue evaluation of structure.
* * * * *

The unsafe condition is reduced structural integrity of the wings, 
fuselage, and stabilizers. We are issuing this AD to require actions to 
correct the unsafe condition on these products.

DATES: This AD becomes effective June 15, 2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of June 15, 
2011.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of January 
20, 1999 (63 FR 69179, December 16, 1998).

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 January 3, 2011 (76 
FR 42), and proposed to supersede AD 98-26-01, Amendment 39-10942 (63 
FR 69179, December 16, 1998), and AD 91-13-01, Amendment 39-7032 (56 FR 
26602, June 10, 1991).
    The NPRM proposed to correct an unsafe condition for the specified 
products. The MCAI states:

    DGAC [Direction G[eacute]n[eacute]rale de l'Aviation Civile] 
France AD 1992-106-132(B) original issue up to revision 7 has been 
issued in order to mandate a set of inspections/modifications which 
address JAR/FAR [Joint Aviation Regulation/Federal Aviation 
Regulation] 25-571 requirements related to damage-tolerance and 
fatigue evaluation of structure [FAA AD 98-26-01 corresponds to DGAC 
AD 1992-106-132(B)R4, dated June 5, 1996].
    Following the Extended Design Service Goal activities part of 
the Structure Task Group for the A310 program, EASA AD 2007-0053 
superseded DGAC France AD F-1992-106-132R7 in order to take into 
account the publication of Airbus Service Bulletins (SB) A310-55-
2004 at Revision 5 and Airbus SB A310-53-2074 at Revision 3, whose 
inspection thresholds and/or intervals had been reduced.
    Revision 1 of this AD was issued to remove the mandatory 
requirements related to the wings (i.e. Sec.  1.8, 1.9, 1.10, 1.13, 
and 1.18) from the Compliance section, which have been transferred 
to EASA AD 2007-0242.
    Revision 2 of this AD has been issued to remove the mandatory 
requirements of paragraph 1.15, 1.16 and 1.17 which have now been 
transferred to EASA AD 2009-0057 (Sec.  1.15 and 1.17) and 2009-0058 
(Sec.  1.16) respectively.
    Revision 3 of this AD is issued to add a Note to the 
Applicability and amend the Required Action(s) and Compliance 
Time(s) section of this AD to clarify the allowed use of the 
referenced SBs by operators. In addition, a note has been added to 
paragraph 1.7 and the notes associated to paragraphs 1.1, 1.2, 1.3, 
1.4, 1.5 and 1.12 have been clarified.

The unsafe condition is reduced structural integrity of the wings, 
fuselage, and stabilizers.
    This NPRM proposed to continue to require certain actions specified 
in AD 98-26-01.
    The NPRM also proposed to expand the inspection area of the high 
frequency eddy current rototest inspection required by paragraph (g) of 
AD 98-26-01. The required actions are as follows, depending on airplane 
configuration:
    <bullet> A defectoscope or rototest inspection to detect cracks in 
the area of frame 47 and frame 54, install new doublers, and repair if 
necessary.
    <bullet> Repetitive visual inspections to detect cracks on frame 46 
between the left- and right-hand sides of stringers 21 and 22 on the 
forward and aft faces, and repair if necessary.
    <bullet> Repetitive visual inspections to detect cracks at the T-
section connecting frame 50A to the beam between the left- and right-
hand sides of frames 50 and 51, and modification if necessary.
    <bullet> Repetitive visual inspections to detect cracks in the 
lower milled side panel at the lap joint with the upper side panel at 
frame 47 and stringer 22, left- and right-hand sides, and repair if 
necessary.
    <bullet> An eddy current inspection to detect cracks on the upper 
integral part adjacent to the rear attach fittings on the horizontal 
stabilizer, modification of the horizontal stabilizer, and repair if 
necessary.
    <bullet> Repetitive high frequency eddy current rototest 
inspections for cracking of the doubler plate edge, rear spar area, and 
at specified fastener holes in the top skin chordwise splice along the 
contour of the steel doubler between ribs 3 and 4 on the left- and 
right-hand center and side boxes on the horizontal stabilizer, 
installing new fasteners if no cracking is found, and repair if 
necessary.
    <bullet> Repetitive inspections, either an eddy current or visual 
inspection, to detect cracks on the left and right vertical posts, 
numbers 1 through 5 inclusive, in the wing center box at frame 40/41, 
and modification 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 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.

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 44 products of U.S. registry. 
The actions that are required by AD 98-26-01 and are retained in this 
AD take about 1,087 work-hours per product, at an average labor rate of 
$85 per work hour. Required parts cost about $81,973 per product. Based 
on these figures, the estimated cost of the currently required actions 
is $174,368 per product.
    We also estimate that it will take about 3 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 $11,220, or $255 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

[[Page 27234]]

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, 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.
