Amendment 39-14286; AD 2005-19-21]
RIN 2120-AA64

Airworthiness Directives; Airbus Model A330-202, -223, -243, and
-343 Airplanes; and Model A340-313 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 A330-202, -223, -243, and -343 airplanes; and
certain Model A340-313 airplanes. This AD requires a one-time
inspection for discrepancies of the attachment bolts of the windshield
central retainer, and corrective actions if necessary. This AD results
from a report indicating that, during production, the windshield
central retainer may have been installed with attachment bolts that
were too short, which prevented the thread of the bolt from fully
engaging in the self-locking nut. We are issuing this AD to prevent
loosened attachment bolts, which could result in loss of the windshield
and consequent reduced structural integrity of the airplane.

DATES: Effective October 7, 2005.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of October 7,
2005.
We must receive comments on this AD by November 21, 2005.

SUPPLEMENTARY INFORMATION:

Discussion

The Direction Generale de l'Aviation Civile (DGAC), which is the
airworthiness authority for France, notified us that an unsafe
condition may exist on certain Airbus Model A330-202, -223, -243, and -
343 airplanes, and Model A340-313 airplanes. The windshield central
retainer is attached with long-thread bolts of a certain length. During
production on affected airplanes, the windshield central

[[Page 55518]]

retainer may have been installed with slightly shorter bolts having
standard thread length. In that case, despite proper torquing, the bolt
thread might not fully engage in the self-locking nut. Loosened
attachment bolts, if not corrected, could result in loss of the
windshield and consequent reduced structural integrity of the airplane.

Relevant Service Information

Airbus has issued Service Bulletins A330-56-3006 and A340-56-4006,
both Revision 01, dated March 24, 2003. The service bulletins describe
procedures for inspecting the windshield central retainer to measure
the protrusion of the attachment bolts, and replacing inadequate bolts
and their corresponding nuts. Accomplishing the actions specified in
the service information is intended to adequately address the unsafe
condition. To ensure the continued airworthiness of these airplanes in
France, the DGAC mandated the service information and issued French
airworthiness directives 2003-123(B) R1 and 2003-124(B) R1, both dated
April 16, 2003.

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 airplanes of this type design that are certificated for
operation in the United States.
Therefore, we are issuing this AD to prevent loosened attachment
bolts of the windshield central retainer, which could result in loss of
the windshield and reduced structural integrity of the airplane. This
AD requires accomplishing the actions specified in the service
information described previously, except as discussed below.

Clarification of Inspection Terminology

The service bulletins refer to a ``detailed visual inspection'' for
measuring the length of the attachment bolts. We have determined that
the procedures in the service bulletins should be considered a
``detailed inspection.'' Note 1 in this AD defines this type of
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. In that event, the required actions would take about 1 work
hour per airplane, at an average labor rate of $65 per work hour. Based
on these figures, we estimate the cost of this AD to be $65 per
airplane.

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.

Comments Invited

This AD is a final rule that involves requirements that affect
flight safety and was not preceded by notice and an opportunity for
public comment; however, we invite you to submit any relevant written
data, views, or arguments regarding this AD. Send your comments to the
address listed under the ADDRESSES section. Include ``Docket No. FAA-
2005-22484; Directorate Identifier 2003-NM-270-AD'' at the beginning of
your comments. We specifically invite comments on the overall
regulatory, economic, environmental, and energy aspects of the AD that
might suggest a need to modify it.
We will post all comments we receive, without change, to http://dms.dot.gov
, including any personal information you provide. We will

also post a report summarizing each substantive verbal contact with FAA
personnel concerning this AD. Using the search function of that Web
site, anyone can find and read the comments in any of our dockets,
including the name of the individual who sent the comment (or signed
the comment on behalf of an association, business, labor union, etc.).
You may review the DOT's complete Privacy Act Statement in the Federal
Register published on April 11, 2000 (65 FR 19477-78), or you may visit
http://dms.dot.gov.

Examining the Docket

You may examine the AD docket on the Internet at http://dms.dot.gov
, or in person at the Docket Management Facility office

between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The Docket Management Facility office (telephone (800) 647-
5227) is located on the plaza level of the Nassif Building at the DOT
street address stated in the ADDRESSES section. Comments will be
available in the AD docket shortly after the Docket Management System
receives them.

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.

Unsafe Condition

(d) This AD results from a report indicating that, during
production, the windshield central retainer may have been installed
with attachment bolts that were too short, which prevented the
thread of the bolt from fully engaging in the self-locking nut. We
are issuing this AD to prevent loosened attachment bolts, which
could result in loss of the windshield and consequent reduced
structural integrity of the airplane.

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.

Inspection

(f) Within 6 months after the effective date of this AD, perform
a detailed inspection of the windshield central retainer for
discrepancies of the attachment bolts, in accordance with the
Accomplishment Instructions of Airbus Service Bulletin A330-56-3006
or A340-56-4006, both excluding Appendix 01, Revision 01, dated
March 24, 2003; as applicable. If the protrusion of any attachment
bolt is not within the limits specified in the service bulletin,
replace the bolt and corresponding nut with new parts before further
flight in accordance with the service bulletin.

Note 1: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''
