[Docket No. FAA-2004-18603; Directorate Identifier 2003-NM-14-AD;
Amendment 39-13850; AD 2004-22-22]
RIN 2120-AA64
Airworthiness Directives; Airbus Model A310 Series Airplanes; and
Model A300 B4-600, B4-600R, and F4-600R Series Airplanes; and Model C4-
605R Variant F Airplanes (Collectively Called A300-600)
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to certain Airbus Model A310 series airplanes; and
Model A300 B4-600, B4-600R, and F4-600R series airplanes; and Model C4-
605R Variant F airplanes (collectively called A300-600). That AD
currently requires modifying the ram air turbine (RAT) by replacing the
ejection jack. This new AD requires a one-time inspection of the RAT
ejection jack to determine the part number, and further investigative
and corrective actions if necessary. This AD is prompted by the
discovery of a rupture in the housing of one of the RAT ejection jacks
installed as specified in the existing AD. We are issuing this AD to
prevent rupture of the housing of the RAT ejection jack due to
overpressure in the jack caused by overfilling the hydraulic fluid, and
consequent failure of the RAT ejection jack. Failure of the ejection
jack could result in a lack of hydraulic pressure or electrical power
in an emergency.
DATES: This AD becomes effective December 14, 2004.
The incorporation by reference of certain publications listed in
the AD is approved by the Director of the Federal Register as of
December 14, 2004.
The incorporation by reference of certain other publications listed
in the AD was approved previously by the Director of the Federal
Register on August 6, 2001 (66 FR 34798, July 2, 2001).

Examining the Docket
The AD docket contains the proposed AD, comments, and any final
disposition. You can examine the 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 DOT

SUPPLEMENTARY INFORMATION: The FAA proposed to amend part 39 of the
Federal Aviation Regulations (14 CFR Part 39) with an AD to supersede
AD 2001-13-16, amendment 39-12297, (66 FR 34798, July 2, 2001). The
existing AD applies to certain Airbus Model A310 series airplanes; and
Model A300 B4-600, B4-600R, and F4-600R series airplanes; and Model C4-
605R Variant F airplanes (collectively called A300-600). The proposed
AD was published in the Federal Register on July 15, 2004 (69 FR
42363), to require a one-time inspection of the RAT ejection jack to
determine the part number, and further investigative and corrective
actions if necessary.
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.
Explanation of Change to Applicability
We have revised the applicability of the AD to identify model
designations as published in the most recent type certificate data
sheet for the affected models.
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. We have determined that this change will
neither increase the economic burden on any operator nor increase the
scope of the AD.
Costs of Compliance
AD 2001-13-16 affects about 117 airplanes of U.S. registry. The
actions that are currently required by AD 2001-13-16 and retained in
this AD take about 6 work hours per airplane, at an average labor rate
of $65 per work hour. There is no charge for required parts. Based on
these figures, the estimated cost of the currently required actions for
U.S. operators is $45,630, or $390 per airplane.
This AD will affect approximately 149 airplanes of U.S. registry.
The new inspection will take about 1 work hour per airplane, at an
average labor rate of $65 per work hour. Based on these figures, the
estimated cost of the new actions specified in this AD for U.S.
operators is $9,685, or $65 per airplane.
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. See the ADDRESSES section for a location to
examine the regulatory evaluation.

Adoption of the Amendment
0
Accordingly, under the authority delegated to me by the Administrator,
[[Page 64855]]
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
2004-22-22 Airbus: Amendment 39-13850. Docket No. FAA-2004-18603;
Directorate Identifier 2003-NM-14-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective December
14, 2004.
Affected ADs
(b) This AD supersedes AD 2001-13-16, amendment 39-12297 (66 FR
34798, July 2, 2001).
Applicability
(c) This AD applies to Airbus Model A310 series airplanes; and
Model A300 B4-600, B4-600R, and F4-600R series airplanes; and Model
C4-605R Variant F airplanes (collectively called A300-600);
certificated in any category; as listed in Airbus Service Bulletin
A300-29-6050, Revision 02, dated April 16, 2003; or A310-29-2088,
Revision 01, dated February 3, 2003.
Unsafe Condition
(d) This AD was prompted by the discovery of a rupture in the
housing of one of the ram air turbine (RAT) ejection jacks installed
as specified in the existing AD. We are issuing this AD to prevent
rupture of the housing of the RAT ejection jack due to overpressure
in the jack caused by overfilling the hydraulic fluid, and
consequent failure of the RAT ejection jack. Failure of the ejection
jack could result in a lack of hydraulic pressure or electrical
power in an emergency.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Requirements of AD 2001-13-16:

A310 series airplanes), or A300-29-6048, Revision 01 (for Model A300
B4-600, B4-600R, and F4-600R series airplanes; and Model C4-605R
