Airworthiness Directives; Airbus Model A340-211, -212, -311, and
-312 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus Model A340-211, -212, -311, and -312 airplanes. This AD
requires an initial rotating probe inspection and initial and
repetitive ultrasonic inspections for discrepancies of the first
fastener hole of the horizontal flange of the keel beam on previously
modified airplanes, installation of new fasteners, and corrective
action if necessary. This AD results from a report that certain
inspections done before accomplishing the modification of the lower
keel beam fitting and forward lower shell connection, revealed cracking
that was outside the modification limits specified in the service
bulletin; the cracking was repaired by installing a titanium doubler.
We are issuing this AD to find and fix discrepancies of the fastener
holes of the horizontal flange of the keel beam, which could result in
reduced structural integrity of the fuselage.
DATES: This AD becomes effective October 27, 2005.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of October 27,
2005.
We must receive comments on this AD by December 12, 2005.

SUPPLEMENTARY INFORMATION:
Discussion
The Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC),
which is the airworthiness authority for France, notified us that an
unsafe condition may exist on certain Airbus Model A340-211, -212, -
311, and -312 airplanes. The DGAC advises that certain inspections done
before accomplishing the modification specified in Airbus Service
Bulletin A340-57-4036 (Airbus Modification 43577), Revision 05, dated
March 14, 2000, revealed cracking that was outside the modification
limits specified in that service bulletin. The cracking was repaired by
installing a titanium doubler using certain repair drawings.
Subsequently, a detailed structural analysis was done on the repaired
airplanes. It was determined by the manufacturer that a specific
inspection program is necessary for the repaired airplanes in order to
maintain structural integrity. Cracking of the fastener holes of the
horizontal flange of the keel beam could result in reduced structural
integrity of the fuselage.
Relevant Service Information
Airbus has issued Service Bulletin A340-57-4087, dated November 21,
2003. The service bulletin describes procedures for an initial rotating
probe inspection and initial and repetitive ultrasonic inspections for
discrepancies (cracking, out-of-tolerance fastener holes, and fastener
damage) of the first fastener hole of the horizontal flange of the keel
beam. If no cracking is found during the rotating probe inspection, the
service bulletin describes procedures for installation of a new
fastener and determining if the fastener hole is out-of-tolerance. The
corrective action for any out-of-tolerance hole includes reaming any
out-of-tolerance fastener holes to oversize and installing oversized
fasteners. The service bulletin also describes procedures for
repetitive follow-on ultrasonic inspections for cracking, and
contacting Airbus for repair instructions if cracking is found.
Accomplishing the actions specified in the service information is
intended to adequately address the unsafe condition. The DGAC mandated
the service information and issued French airworthiness directive F-
2005-007, dated January 5, 2005, to ensure the continued airworthiness
of these airplanes in France.
The service bulletin also specifies to contact the manufacturer for
disposition of certain repair conditions and report inspection findings
to the manufacturer. The service bulletin refers to Airbus Service
Bulletin A340-57-4036, Revision 05, dated March 14, 2000, as the source
of service information for accomplishing Airbus Modification 43577. The
modification was previously accomplished on all airplanes affected by
this AD.
FAA's Determination and Requirements of This AD
These airplane models are manufactured in France and are type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the DGAC has kept the FAA informed
of the situation described above. We have examined the DGAC's findings,
evaluated all pertinent information, and determined that we need to
issue an AD for products of this type design that are certificated for
operation in the United States.
Therefore, we are issuing this AD to find and fix discrepancies of
the fastener holes of the horizontal flange of the keel beam, which
could result in reduced structural integrity of the fuselage. This AD
requires accomplishing the actions specified in Service Bulletin A340-
57-4087, described previously, except as discussed under ``Difference
Between this AD, the French Airworthiness Directive, and Service
Bulletin A340-57-4087.''
Difference Between This AD, the French Airworthiness Directive, and
Service Bulletin A340-57-4087
The French airworthiness directive and the service bulletin specify
contacting the manufacturer for disposition of certain repair
conditions; this AD requires the repair of those conditions to be
accomplished per a method approved by either the FAA or the DGAC (or
its delegated agent). In light of the type of repair that would be
required to address the identified unsafe condition, and in consonance
with existing bilateral airworthiness agreements, the FAA has
determined that, for this AD, a repair approved by either the FAA or
the DGAC (or its delegated agent) would be acceptable for compliance
with this AD.
Although the French airworthiness directive allows for use of the
procedures specified in Airbus Technical Disposition F57D03012810 or
582.0651/2002 for accomplishing the first rotating probe inspection,
this AD does not allow for those documents to be used. This difference
has been coordinated with the DGAC.
Clarification of Compliance Time
The service bulletin and French airworthiness directive do not
provide a compliance time for the initial ultrasonic inspection if no
cracking is found during the rotating probe inspection; however, this
AD requires that the inspection be done within 1,480 flight cycles or
7,400 flight hours after accomplishing the one-time rotating probe
inspection.
Costs of Compliance
None of the airplanes affected by this action are on the U.S.
Register. All airplanes affected by this AD are currently operated by
non-U.S. operators under foreign registry; therefore, they are not
directly affected by this AD action. However, we consider this AD
necessary to ensure that the unsafe condition is addressed if any
affected airplane is imported and placed on the U.S. Register in the
future.
If an affected airplane is imported and placed on the U.S. Register
in the future, it would take between 3 and 8 work hours per airplane
for the initial inspections and about 2 work hours per airplane for
each repetitive inspection, at an average labor rate of $65 per work
hour. Two kits would be required for installing the new fasteners after
discarding the removed fasteners. Parts cost is $190 for each kit.
Based on these figures, the estimated cost of the initial actions would
be between $575 and $900 per airplane; and the estimated cost of the
repeat inspection is estimated to be $130 per airplane, per inspection
cycle.
FAA's Determination of the Effective Date
No airplane affected by this AD is currently on the U.S. Register.
Therefore, providing notice and opportunity for public comment is
unnecessary before this AD is issued, and this AD may be made effective
in less than 30 days after it is published in the Federal Register.

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