Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2008-1201; Directorate Identifier 2008-NM-007-AD; 
Amendment 39-15922; AD 2009-11-12]
RIN 2120-AA64

 
Airworthiness Directives; Airbus Model A310 Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is superseding an existing airworthiness directive 
(AD), which applies to certain Airbus Model A310 series airplanes. That 
AD currently requires repetitive inspections of the fuselage skin to 
detect corrosion or fatigue cracking around and under the chafing 
plates of the wing root; repetitive inspections for fatigue cracking of 
frame 39, stringer 35; and corrective actions if necessary. The 
existing AD also provides for an optional terminating action for 
certain repetitive inspections, except for certain areas where 
corrosion was detected and reworked. This new AD reduces the intervals 
for accomplishing repetitive inspections in a certain area. This AD 
results from mandatory continuing airworthiness information originated 
by an aviation authority of another country to identify and correct an 
unsafe condition on an aviation product. We are issuing this AD to 
detect and correct fatigue cracks and corrosion around and under the 
chafing plates of the wing root, which could result in reduced 
structural integrity of the airplane.

DATES: This AD becomes effective August 25, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of August 25, 
2009.
    The Director of the Federal Register previously approved the 
incorporation by reference of Airbus Service Bulletin A310-53-2070, 
dated October 3, 1994, on June 3, 1998 (63 FR 23377, April 29, 1998).

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to include an AD that supersedes AD 2004-14-06, amendment 
39-13715 (69 FR 41401, July 9, 2004). The existing AD applies to 
certain Airbus Model A310 series airplanes. That NPRM was published in 
the Federal Register on November 13, 2008 (73 FR 67110). That NPRM 
proposed to continue to require repetitive inspections of the fuselage 
skin to detect corrosion or fatigue cracking around and under the 
chafing plates of the wing root; repetitive inspections for fatigue 
cracking of frame 39, stringer 35; and corrective actions if necessary. 
That NPRM also proposed to continue to provide for an optional 
terminating action for certain repetitive inspections, except for 
certain areas where corrosion was detected and reworked. In addition, 
that NPRM proposed to reduce the intervals for accomplishing the 
repetitive inspections in a certain area.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comment that has been 
received on the NPRM. FedEx supports the NPRM.

Revisions to Paragraphs (f), (h), (i), and (j) of This AD

    We have revised paragraph (h) of this AD to give credit for actions 
done in accordance with Airbus Service Bulletin A310-53-2070, Revision 
1, dated September 23, 1996. We also added Airbus Service Bulletin 
A310-53-2069, Revision 06, dated May 22, 2007, as an acceptable source 
of service information for compliance with the requirements of 
paragraphs (f) and (i) of this AD. We have also revised paragraph (j) 
of this AD to include a new Table 1 to specify the number, revision, 
and date of each service bulletin for which no reporting is required.

Conclusion

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

Costs of Compliance

    This AD affects about 69 Model A310 series airplanes of U.S. 
registry. The actions that are required by AD 2004-14-06 and retained 
in this AD take about 68 work hours per airplane, at an average labor 
rate of $80 per work hour. Based on these figures, the estimated cost 
of the currently required actions is $375,360, or $5,440 per airplane, 
per inspection cycle.

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 have determined that this AD will not have federalism 
implications under

[[Page 35778]]

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 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. See the ADDRESSES 
section for a location to examine the regulatory evaluation.
