14 CFR Part 39
[Docket No. FAA-2006-24990; Directorate Identifier 2006-NM-013-AD;
Amendment 39-14772; AD 2006-20-03]
RIN 2120-AA64
Airworthiness Directives; Airbus Model A319, A320, and A321
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Airbus Model A319, A320, and A321 airplanes. This AD requires
an inspection to determine if the stiff part of the girt and girt bar
position of the forward left-hand and right-hand passenger doors is
incorrect, and repair if necessary. This AD results from cases of girt
bar disengagement from the floor fitting during deployment tests of
slide rafts at the forward passenger doors. We are issuing this AD to
prevent disengagement of the telescopic girt bar from the airplane when
the door is opened in emergency situations, which could result in the
inability to open the passenger door and to use the escape slide/raft
at that door during an emergency evacuation of the airplane.
DATES: This AD becomes effective November 2, 2006.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of November 2,
2006.
ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov

Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Airbus Model
A319, A320, and A321 airplanes. That NPRM was published in the Federal
Register on June 12, 2006 (71 FR 33661). That NPRM proposed to require
an inspection to determine if the stiff part of the girt and girt bar
position of the forward left-hand and right-hand passenger doors is
incorrect, and repair if necessary.
Comments
We provided the public the opportunity to participate in the
development of this AD. We have considered the comments received.
Support for the NPRM
Airbus agrees with the NPRM.
Request To Withdraw the NPRM
The Air Transport Association (ATA), on behalf of its member, US
Airways, requests that we clarify the impact of AD 2005-23-05 on the
NPRM. (On October 25, 2005, we issued AD 2005-23-05, amendment 39-14363
(70 FR 69063, November 14, 2005), for certain Airbus Model A319-100,
A320-200, and A321-100 and -200 series
[[Page 56855]]
airplanes. AD 2005-23-05 requires modification of the telescopic girt
bar of the escape slide/raft assembly, and follow-on actions. AD 2005-
23-05 also requires a new modification of the telescopic girt bar and
the installation of placards on the modified girt bars, which terminate
the repetitive functional tests. We issued AD 2005-23-05 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.) US Airways
states that the intent of the NPRM has already been accomplished with
AD 2005-23-05. US Airways asserts that AD 2005-23-05 requires
replacement of the telescopic girt bar on affected slide rafts, and
that during replacement of the girt bar, the girt is reinstalled using
the same instructions referenced in the NPRM. US Airways points out
that the compliance time of AD 2005-23-05 is August 19, 2007.
Therefore, US Airways requests that we either withdraw the NPRM or
grant AD 2005-23-05 as an alternative method of compliance (AMOC) to
the NPRM.
We do not agree to withdraw this AD, since the applicability of AD
2005-23-05 and this AD do not exactly match. Also, this AD mandates a
shorter compliance time than AD 2005-23-05. However, we do agree to
provide credit for accomplishing the actions in paragraph (g) of AD
2005-23-05. Paragraph (g) of AD 2005-23-05 references Airbus Service
Bulletin A320-52-1112, Revision 05, dated June 25, 2004, as the
appropriate source of service information for modifying the telescopic
girt bar. We have reviewed Airbus Service Bulletin A320-52-1112,
Revision 05, and have determined that accomplishing the actions in that
service bulletin is acceptable for accomplishing the actions specified
in paragraph (f) of this AD. Therefore, we have added a new paragraph
(h) to this AD allowing credit for accomplishment of paragraph (g) of
AD 2005-23-05. We have reidentified the subsequent paragraphs
accordingly.
Change to the Cost of Compliance
We have reduced our estimate for the number of affected airplanes
of U.S. registry.
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.
We have determined that the changes will neither increase the economic
burden on any operator nor increase the scope of the AD.
Costs of Compliance
This AD affects about 200 airplanes of U.S. registry. The actions
in this AD take about 1 work hour per airplane, at an average labor
rate of $80 per work hour. Based on these figures, the estimated cost
of the AD for U.S. operators is $16,000, or $80 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.
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.
