14 CFR Part 39
[Docket No. 2003-NM-12-AD; Amendment 39-13717; AD 2004-14-08]
RIN 2120-AA64
Airworthiness Directives; Airbus Model A300 B4-600, B4-600R, C4-
605R Variant F, and F4-600R (Collectively Called A300-600), and A310
Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to certain Airbus Model A300-600 and A310 series airplanes,
that requires modification of the attachment system of the insulation
blankets of the forward cargo compartment and related corrective
action. This action is necessary to prevent failure of the attachment
system of the cargo insulation blankets, which could result in
detachment and consequent tearing of the blankets. Such tearing could
result in blanket pieces being ingested into and jamming the forward
outflow valve of the pressure regulation subsystem, which could lead to
cabin depressurization and adversely affect continued safe flight of
the airplane. This action is intended to address the identified unsafe
condition.
DATES: Effective August 17, 2004.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of August 17, 2004.
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,
1601 Lind Avenue, SW., Renton, Washington; or at the National Archives
and Records Administration (NARA). For information on the availability

FOR FURTHER INFORMATION CONTACT: Dan Rodina, Aerospace Engineer,
International Branch, ANM-116, FAA, Transport Airplane Directorate,

227-2125; fax (425) 227-1149.
SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to certain Airbus Model A300-600 and
A310 series airplanes was published in the Federal Register on April 6,
2004 (69 FR 17996). That action proposed to require modification of the
attachment system of the insulation blankets of the forward cargo
compartment and related corrective action.
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been submitted on the proposed
AD or on the determination of the cost to the public.
Revised Service Information
Since issuance of the proposed AD, the manufacturer has revised the
referenced service information. Therefore, we have changed paragraph
(a) of this final rule to refer to Airbus Service Bulletins A300-21-
6045 (for Model A300-600 series airplanes) and A310-21-2059 (for Model
A310 series airplanes), both Revision 02, both dated March 27, 2003,
for accomplishment of the modification of the attachment system of the
insulation blankets of the
[[Page 41926]]
forward cargo compartment. We have also noted that accomplishment of
the modification before the effective date of this AD using Revision 01
of the service bulletins is acceptable for compliance with that
paragraph. Revision 02 has been identified as mandatory and contains
procedures that are essentially the same as those in Revision 01
(referenced in the proposed AD as the appropriate source of service
information for accomplishment of the actions).
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD with the
change described previously. This change will neither increase the
economic burden on any operator nor increase the scope of the AD.
Cost Impact
We estimate that 149 airplanes of U.S. registry will be affected by
this AD, that it will take about 3 work hours per airplane to
accomplish the modification, and that the average labor rate is $65 per
work hour. Required parts will cost about $198 per airplane. Based on
these figures, the cost impact of the AD on U.S. operators is estimated
to be $58,557, or $393 per airplane.
The cost impact figure discussed above is 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

regulation subsystem, which could lead to cabin depressurization and
adversely affect continued safe flight of the airplane, accomplish
the following:

A310 series airplanes), both Revision 02, both dated March 27, 2003,
as applicable. Repair any damaged insulation blanket before further
flight, per the applicable service bulletin. Actions accomplished
before the effective date of this AD per Airbus Service Bulletin
A300-21-6045 or A310-21-2059, both Revision 01, both dated May 22,
2002, are acceptable for compliance with the corresponding action
required by this paragraph.
