Airworthiness Directives; Airbus Model A310 Series Airplanes and 
Model A300-600 Series Airplanes

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

ACTION: Final rule.

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

SUMMARY: This airworthiness directive (AD) supersedes two existing ADs. 
One AD applies to certain Airbus Model A310-200 and -300 series 
airplanes. That AD currently requires repetitive inspections for 
cracking of the flap transmission shafts, and replacement of the 
transmission shafts if necessary. That AD also provides an optional 
terminating action for the repetitive inspections. The other existing 
AD applies to all Airbus Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model C4-605R Variant F airplanes (collectively called 
A300-600 series airplanes); and Model A310-200 and -300 series 
airplanes. That AD currently requires a one-time inspection of the 
trimmable horizontal stabilizer actuator (THSA), corrective actions if 
necessary, and follow-on repetitive tasks. This new AD also requires 
revising the Airworthiness Limitations Section of the Instructions for 
Continued Airworthiness to incorporate new limitations and maintenance 
tasks for aging systems maintenance. This AD results from the 
manufacturer's determination that life limitations and maintenance 
tasks are necessary to ensure continued operational safety of the 
affected airplanes. We are issuing this AD to prevent reduced 
structural integrity of these airplanes due to the failure of system 
components.

DATES: This AD becomes effective April 28, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in the AD as of April 28, 
2009.
    On August 29, 2006 (71 FR 42021, July 25, 2006), the Director of 
the Federal Register approved the incorporation by reference of Airbus 
Service Bulletin A300-27-6044, Revision 04, dated September 10, 2001; 
and Airbus Service Bulletin A310-27-2089, Revision 02, dated June 28, 
2001.
    On June 20, 2006 (71 FR 28254, May 16, 2006), the Director of the 
Federal Register approved the incorporation by reference of Airbus 
Service Bulletin A310-27-2092, Revision 02, dated April 11, 2005; and 
Airbus Service Bulletin A310-27-2095, dated March 29, 2000.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued a supplemental notice of proposed rulemaking (NPRM) 
to amend 14 CFR part 39 to include an AD that supersedes two existing 
ADs: AD 2006-10-11, amendment 39-14595 (71 FR 28254, May 16, 2006); and 
AD 2006-15-10, amendment 39-14690 (71 FR 42021, July 25, 2006). AD 
2006-10-11 applies to certain Airbus Model A310-200 and -300 series 
airplanes and requires repetitive inspections for cracking of the flap 
transmission shafts, and replacing the transmission shafts if 
necessary. That existing AD also provides an optional terminating 
action for the repetitive inspections. AD 2006-15-10 applies to all 
Airbus Model A310 and A300-600 series airplanes and requires a one-time 
inspection of the trimmable horizontal stabilizer actuator (THSA), 
corrective actions if necessary, and follow-on repetitive tasks.
    That supplemental NPRM was published in the Federal Register on 
September 26, 2008 (73 FR 55781). That supplemental NPRM proposed to 
continue to require the actions required by the two existing ADs. That 
supplemental NPRM also proposed to require revising the Airworthiness 
Limitations Section of the Instructions for Continued Airworthiness to 
incorporate new limitations and maintenance tasks for aging systems 
maintenance. In addition, that supplemental NPRM proposed to revise the 
original NPRM by reducing the initial compliance times.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. No comments have been received on the 
supplemental NPRM or on the determination of the cost to the public.

Explanation of Changes

    We have removed the ``Service Bulletin References'' paragraph in 
the ``RESTATEMENT OF REQUIREMENTS OF AD 2006-15-10'' section of this 
AD. Instead, we refer to the required service documents in the 
individual paragraphs of this AD.

Conclusion

    We have carefully reviewed the available data 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

    The following table provides the estimated costs for U.S. operators 
to comply with this AD.

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 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.

2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
removing amendment 39-14595 (71 FR 28254, May 16, 2006), and amendment 
39-14690 (71 FR 42021, July 25, 2006), and by adding the following new 
airworthiness directive (AD):

2009-06-06 Airbus: Amendment 39-15842. Docket No. FAA-2008-0018; 
Directorate Identifier 2007-NM-145-AD.

Effective Date

    (a) This AD becomes effective April 28, 2009.

Affected ADs

    (b) This AD supersedes AD 2006-10-11 and AD 2006-15-10.

Applicability

    (c) This AD applies to all Airbus Model A310 series airplanes; 
and Model A300-600 series airplanes; certificated in any category.

    Note 1: This AD requires revisions to certain operator 
maintenance documents to include new inspections. Compliance with 
these inspections is required by 14 CFR 91.403(c). For airplanes 
that have been previously modified, altered, or repaired in the 
areas addressed by these inspections, the operator may not be able 
to accomplish the inspections described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according 
to paragraph (q) of this AD. The request should include a 
description of changes to the required inspections that will ensure 
the continued operational safety of the airplane.

Unsafe Condition

    (d) This AD results from the manufacturer's determination that 
life limitations and maintenance tasks are necessary to ensure 
continued operational safety of the affected airplanes. We are 
issuing this AD to prevent reduced structural integrity of these 
airplanes due to the failure of system components.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.
