AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing AD that applies to certain
Airbus Model A318, A319, A320, and A321 airplanes. That AD currently
requires repetitive detailed inspections of the inboard flap trunnions
for any wear marks and of the sliding panels for any cracking at the
long edges, and corrective actions if necessary. This new AD adds
airplanes that were recently added to the type certificate data sheet
and changes the inspection type. This AD results from reports of wear
damage to the inboard flap trunnions after incorporation of the
terminating modification. We are issuing this AD to detect and correct
wear of the inboard flap trunnions, which could lead to loss of flap
surface control and consequently result in the flap detaching from the
airplane. A detached flap could result in damage to the tail of the
airplane.
DATES: This AD becomes effective April 16, 2008.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of April 16,
2008.
On March 24, 2006 (71 FR 8439, February 17, 2006), the Director of
the Federal Register approved the incorporation by reference of Airbus
Service Bulletin A320-57-1133, excluding Appendix 01, dated July 28,
2005.
On January 8, 2001 (65 FR 75603, December 4, 2000), the Director of
the Federal Register approved the incorporation by reference of certain
other publications listed in the AD.

SUPPLEMENTARY INFORMATION:
Discussion
The FAA issued a second supplemental notice of proposed rulemaking
(NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD
2006-04-06, amendment 39-14487 (71 FR 8439, February 17, 2006). The
existing AD applies to certain Airbus Model A318, A319, A320, and A321
airplanes. That second supplemental NPRM was published in the Federal
Register on August 16, 2007 (72 FR 45982). That second supplemental
NPRM proposed to supersede an existing AD that currently requires
repetitive detailed inspections of the inboard flap trunnions for any
wear marks and of the sliding panels for any cracking at the long
edges, and corrective actions if necessary. That second supplemental
NPRM proposed to add airplanes that were recently added to the type
certificate data sheet and change the inspection type.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Request To Include Revised Service Information
Airbus asks that Airbus Service Bulletin A320-57-1133, Revision 03,
dated July 3, 2007, be incorporated into
[[Page 13085]]
the AD. (We referred to Revision 02, dated December 12, 2006, of that
service bulletin as the appropriate source of service information for
accomplishing certain actions specified in the second supplemental
NPRM.)
We agree with Airbus and have changed the applicable paragraphs in
this AD to refer to Revision 03 of Airbus Service Bulletin A320-57-1133
for accomplishing certain actions, as no additional work is required by
this revision. We have also changed paragraph (k) of this AD to give
credit to operators who have accomplished the actions in accordance
with Airbus Service Bulletin A320-57-1133, Revision 02, dated December
12, 2006, before the effective date of this AD.
Request To Include Inspections Removed From Second Supplemental NPRM
Under the ``Request to Remove Certain Requirements'' section of the
second supplemental NPRM, certain requirements were removed based on a
previous recommendation from Airbus. Regarding that recommendation,
Airbus notes that Model A321-211 and -231 airplanes that are pre-
modification 26495, and on which Airbus Service Bulletin A320-27-1117,
Revision 04, dated November 6, 2001, was not applied, should have
dedicated procedures included in the AD. Airbus states that the
inspections specified in Airbus Service Bulletin A320-27-1108, Revision
04, dated November 22, 1999, provide those procedures.
We agree with Airbus, although there are no U.S. operators of Model
A321-211 and -231 airplanes that are specified in the effectivity that
are pre-modification 26495. In the unlikely event that an operator has
an airplane configuration that is pre-modification 26495, or on which
Airbus Service Bulletin A320-27-1117 was applied, we have determined
that the alternative inspections specified in Airbus Service Bulletin
A320-27-1108, Revision 04, can be used, as the inspections provide an
acceptable level of safety. We have added a new paragraph (p) to this
AD to include the alternate inspections.
Conclusion
We have carefully reviewed the available data, including the
comments received, and determined that air safety and the public
interest require adopting the AD with the changes described previously.
These changes will neither increase the economic burden on any operator
nor 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.
Estimated Costs

Average Number of
Work labor U.S.-

cycle. cycle.
General visual inspection (new action) 1 80 None..................... $80, per inspection 754 $60,320, per inspection
cycle. cycle.
--------------------------------------------------------------------------------------------------------------------------------------------------------
Currently, there are no affected Model A321-211 and -231 airplanes
on the U.S. Register. However, if an affected airplane is imported and
placed on the U.S. Register in the future, the required inspection
would take about 1 work hour, at an average labor rate of $80 per work
hour. Based on these figures, we estimate the cost of this AD to be $80
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 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.
