14 CFR Part 39

[Docket No. FAA-2004-19863; Directorate Identifier 2003-NM-29-AD; 
Amendment 39-14363; AD 2005-23-05]
RIN 2120-AA64


Airworthiness Directives; Airbus Model A319-100, A320-200, and 
A321-100 and -200 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 A319-100, A320-200, and 
A321-100 and -200 series airplanes. That AD currently requires 
modification of the telescopic girt bar of the escape slide/raft 
assembly, and follow-on actions. This new AD requires a new 
modification of the telescopic girt bar and the installation of 
placards on the modified girt bars, which terminates the repetitive 
functional tests required by the existing AD. This AD results from 
development of a new, improved modification. We are issuing this AD to 
prevent failure of the escape slide/raft to deploy correctly, which 
could result in the slide being unusable during an emergency evacuation 
and consequent injury to passengers or airplane crewmembers.

DATES: This AD becomes effective December 19, 2005.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of December 19, 
2005.
    On August 31, 2001 (66 FR 42939, August 16, 2001), the Director of 
the Federal Register approved the incorporation by reference of Airbus 
Industrie All Operators Telex A320-52A1111, Revision 01, dated July 23, 
2001, including Airbus Industrie Technical Disposition 959.1492/01, 
Issue C, dated July 17, 2001.

ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov or in person at the Docket Management Facility, U.S. 
Department of Transportation, 400 Seventh Street, SW., Nassif Building, 
room PL-401, Washington, DC.
    Contact Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex, 
France, for service information identified in this AD.

SUPPLEMENTARY INFORMATION:

Examining the Docket

    You may examine the airworthiness directive (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 street address stated in the ADDRESSES section.

Discussion

    The FAA issued a supplemental notice of proposed rulemaking (NPRM) 
to amend 14 CFR part 39 to include an AD that supersedes AD 2001-16-14, 
amendment 39-12383 (66 FR 42939, August 16, 2001). The existing AD 
applies to certain Airbus Model A319, A320, and A321 series airplanes. 
That supplemental NPRM was published in the Federal Register on July 
21, 2005 (70 FR 42005). That supplemental NPRM proposed to mandate the 
installation of placards on the modified girt bars, which terminates 
the repetitive functional tests required by the existing AD.

Comments

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

Clarification of Alternative Method of Compliance (AMOC) Paragraph

    We have changed this AD to clarify the appropriate procedure for 
notifying the principal inspector before using any approved AMOC on any 
airplane to which the AMOC applies.

Conclusion

    We have carefully reviewed the available data, including the 
comment that has been received, and determined that air safety and the 
public interest require adopting the AD as proposed.

Costs of Compliance

    This AD will affect about 517 airplanes of U.S. registry.
    The modification that is required by AD 2001-16-14 and retained in 
this AD takes about 7 work hours per airplane, at an average labor rate 
of $65 per work hour. The cost of required parts is negligible. Based 
on these figures, the estimated cost of the currently required 
modification for U.S. operators is $235,235, or $455 per airplane.
    The functional test that is required by AD 2001-16-14 and retained 
in this AD takes about 1 work hour per airplane, at an average labor 
rate of $65 per work hour. Based on these figures, the cost impact of 
the currently required functional test for U.S. operators is $33,605, 
or $65 per airplane, per test cycle.
    For airplanes that have not been modified in accordance with AD 
2001-16-14: The new modification (including the new placard 
installation) takes about 17 work hours per airplane, at an average 
labor rate of $65 per work hour. Required parts cost about $5,130 per 
airplane. Based on these figures, the estimated cost of the new 
modification specified in this AD is $6,235 per airplane.
    For airplanes that have been modified in accordance with AD 2001-
16-14: The new modification (including the new placard installation) 
takes about 21 work hours per airplane, at an average labor rate of $65 
per work hour. Required parts cost about $5,130 per airplane. Based on 
these figures, the estimated cost of the new modification specified in 
this AD is $6,495 per airplane.

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.

[[Page 69064]]

    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.
