Airworthiness Directives; Airbus Model A319 and A320-200 Series 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to certain Airbus Model A319 and A320-200 series 
airplanes, that currently requires repetitive inspections to detect 
loose, missing, or discrepant rivets in specified areas of the door 
frames of the overwing emergency exits; measurement of the grip length 
of all rivets in the specified areas; and corrective action if 
necessary, which terminates the repetitive inspections. This new 
amendment also requires an inspection for correct dimensions of the 
interior countersinks of the rivet holes, and related corrective 
action. The actions specified by this AD are intended to prevent loose, 
missing, or discrepant rivets, which could lead to reduced structural 
integrity of the door frames of the overwing emergency exits. This 
action is intended to address the identified unsafe condition.

DATES: Effective February 9, 2005.
    The incorporation by reference of certain service information, as 
listed in the regulations, is approved by the Director of the Federal 
Register as of February 9, 2005.
    The incorporation by reference of certain other service 
information, as listed in the regulations, was approved previously by 
the Director of the Federal Register as of April 5, 2002 (67 FR 9392, 
March 1, 2002).

ADDRESSES: The service information referenced in this AD may be 
obtained from Airbus, 1 Rond Point Maurice Bellonte, 31707 Blagnac 
Cedex, France. This information may be examined at the Federal Aviation 
Administration (FAA), Transport Airplane Directorate, Rules Docket,

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) by superseding AD 2002-04-10, 
amendment 39-12667 (67 FR 9392, March 1, 2002), which is applicable to 
certain Airbus Model A319 and A320-200 series airplanes, was published 
in the Federal Register on April 7, 2004 (69 FR 18304). The action 
proposed to retain the existing requirements for repetitive inspections 
for loose, missing, or discrepant rivets in specified areas of the door 
frames of the overwing emergency exits; and measurement of the grip 
length of all rivets in the specified areas; and corrective action if 
necessary, which terminates the repetitive inspections. The proposed AD 
also proposed to add an inspection for correct dimensions of the 
interior countersinks of the rivet holes, and related corrective 
action.

Comments

    We provided the public the opportunity to participate in the 
development of this AD. We have considered the comments that have been 
submitted on the proposed AD. The commenters support the proposed AD.

Conclusion

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

Cost Impact

    This AD affects about 168 airplanes of U.S. registry.
    The inspections required by AD 2002-04-10 take about 1 work hour 
per airplane, at an average labor rate of $65 per work hour. Based on 
these figures, the cost impact of those inspections is estimated to be 
$65 per airplane, per inspection cycle.
    The new inspection required by 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 new inspection on U.S. operators is 
estimated to be $10,920, or $65 per airplane.
    The cost impact figures discussed above are based on assumptions 
that no operator has yet accomplished any of the requirements of this 
AD, and that no operator would accomplish those actions in the future 
if this AD were not adopted. The cost impact figures discussed in AD 
rulemaking actions represent only the time necessary to perform the 
specific actions actually required by the AD. These figures typically 
do not include incidental costs, such as the time required to gain 
access and close up, planning time, or time necessitated by other 
administrative actions.

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 Impact

    The regulations adopted herein 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. Therefore, it 
is determined that this final rule does not have federalism 
implications under Executive Order 13132.
    For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action 
and it is contained in the Rules Docket. A copy of it may be obtained 
from the Rules Docket at the location provided under the caption 
ADDRESSES.
