Airworthiness Directives; Airbus Model A330 and A340 Series 
Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

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

SUMMARY: This amendment supersedes an existing airworthiness directive 
(AD), applicable to certain Airbus Model A330 and A340 series 
airplanes, that currently requires a one-time inspection of the rail 
release pins and parachute pins of the escape slide/raft pack assembly 
for correct installation, and corrective actions, if necessary. This 
amendment adds a requirement to modify the escape slides/slide rafts on 
the passenger, crew, and emergency exit doors. The actions specified by 
this AD are intended to prevent improper deployment of the escape 
slide/raft and blockage of the door in the event of an emergency 
evacuation. This action is intended to address the identified unsafe 
condition.

DATES: Effective March 5, 2003.
    The incorporation by reference of Airbus Service Bulletin A330-25-
3126, dated August 7, 2001; and Airbus Service Bulletin A340-25-4152, 
dated August 7, 2001; as listed in the regulations, is approved by the 
Director of the Federal Register as of March 5, 2003.
    The incorporation by reference of Airbus Industrie Service Bulletin 
A330-25-3086, including Appendix 01, Revision 01, dated June 11, 1999; 
and Airbus Industrie Service Bulletin A340-25-4115, including Appendix 
01, Revision 01, dated June 11, 1999; as listed in the regulations, was 
approved previously by the Director of the Federal Register as of 
November 26, 1999 (64 FR 56963, October 22, 1999).

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

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal 
Aviation Regulations (14 CFR part 39) by superseding AD 99-22-07, 
amendment 39-11385 (64 FR 56963, October 22, 1999), which is applicable 
to certain Airbus Model A330 and A340 series airplanes, was published 
in the Federal Register on September 13, 2002 (67 FR 57982). The action 
proposed to continue to require a one-time inspection of the rail 
release pins and parachute pins of the escape slide/raft pack assembly 
for correct installation, and corrective actions, if necessary. The 
action also proposed to require modification of the escape slides/slide 
rafts on the passenger, crew, and emergency exit doors.

Comments

    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. Due consideration has been given to 
the comments received.

[[Page 4379]]

Request To Allow Part Installations

    Two commenters request that the notice of proposed rulemaking 
(NPRM) be revised to allow installation of an unmodified slide on Model 
A330 series airplanes, until the compliance deadline. These commenters 
state that if the AD does not allow unmodified slides to be installed 
after the effective date of the AD, all unmodified spares would become 
unserviceable at that time. This would require the personnel at the 
slide shops to complete spares modification at an accelerated rate, 
which would increase the cost of this modification.
    The FAA does not agree. This AD does not contain any provisions 
that prohibit operators from installing an unmodified slide on an 
airplane before they accomplish the modification required by paragraph 
(b) of this AD. However, once the compliance threshold (i.e., 36 months 
after the effective date of this AD) has been reached for modification, 
operators are prohibited from replacing an improved part with an old 
part under 14 Code of Federal Regulations (CFR) 39.3. No change to the 
final rule is necessary.

Conclusion

    After careful review of the available data, including the comments 
noted above, we have determined that air safety and the public interest 
require the adoption of the rule as proposed.

Cost Impact

    There are approximately nine airplanes of U.S. registry that will 
be affected by this AD.
    The inspection currently required by AD 99-22-07 takes 
approximately 7 work hours per airplane to accomplish, at an average 
labor rate of $60 per work hour. Based on these figures, the cost 
impact of the currently required actions on U.S. operators is estimated 
to be $3,780, or $420 per airplane.
    The modification required in this AD action will take approximately 
11 work hours per airplane to accomplish, at an average labor rate of 
$60 per work hour. Required parts will cost approximately $3,136 per 
airplane. Based on these figures, the cost impact of the requirements 
of this AD on U.S. operators is estimated to be $34,164, or $3,796 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 action, 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.

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.
