Airworthiness Directives; Airbus Model A330, A340-200, and A340-
300 Series Airplanes
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD);
applicable to certain Airbus Model A330, A340-200, and A340-300 series
airplanes; that requires inspecting the ram air turbine (RAT) actuator
to determine its serial number; and re-identifying the RAT actuator,
inspecting the RAT actuator to determine whether the rotary solenoids
are in the correct position, and replacing the RAT actuator, as
applicable. This action is necessary to prevent failure of the RAT
actuator to deploy when necessary during flight, which could result in
reduced controllability of the airplane. This action is intended to
address the identified unsafe condition.
DATES: Effective December 21, 2004.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of December 21, 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,

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 A330, A340-
200, and A340-300 series airplanes was published in the Federal
Register on April 1, 2004 (69 FR 17109). That action proposed to
require inspecting the ram air turbine actuator (RAT) to determine its
serial number; and re-identifying the RAT actuator, inspecting the RAT
actuator to determine whether the rotary solenoids are in the correct
position, and replacing the RAT actuator, as applicable.
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 from a single commenter.
Request To Expand Applicability To Include Additional Models
The commenter, the airplane manufacturer, notes that French
airworthiness directive 2002-422(B) R1, dated January 22, 2003, applies
to Airbus Model A330-201, -202, -203, -223, -243, -301, -321, -322, -
323, -341, -342, and -343 airplanes, equipped with certain RAT modules.
The commenter notes that the French airworthiness directive will have
to be revised to apply to Airbus Model A330-302 and -303 airplanes when
those airplanes are certificated.
We infer that the commenter is requesting that we revise the
proposed AD to include the additional models. We do not concur. Airbus
Model A330-302 and -303 airplanes are not certificated in the United
States as of the preparation of this final rule. If these models are
certificated in the United States in the future, we may consider
rulemaking to require actions similar to those required by this AD on
those airplanes, if necessary. We have made no change to this AD.
Request To Revise Compliance Time
The commenter notes that the proposed AD differs from French
airworthiness directives 2002-422(B) R1 and 2002-423(B) R1, both dated
January 22, 2003, in the compliance time for the one-time inspection to
determine if the rotary solenoids are in the correct position. We infer
that the commenter is referring to the fact that French airworthiness
directives 2002-422(B) R1 and 2002-423(B) R1 require that this
inspection be done ``not later than August 31, 2004,'' while the
proposed AD specifies a compliance of 24 months after the effective
date of the AD for the same action.
We infer that the commenter is requesting that we revise the
[[Page 67051]]
compliance time to correspond to the compliance time in the French
airworthiness directives for the inspection to determine if the rotary
solenoids are in the correct position. We do not concur that a change
is necessary. We express compliance times based on calendar dates
(e.g., ``before January 1, 1993'') only when engineering analysis
establishes a direct relationship between the date and the compliance
time. In this case, no direct relationship exists. We note that
paragraph 3., ``Compliance'' of the French airworthiness directives
states that ``the following measures are rendered mandatory from the
effective date of this AD at original issue.'' The compliance time for
the subject inspection in the French airworthiness directives, August
31, 2004, corresponds to 24 months after the effective date of the
original issue of the French airworthiness directives (August 31,
2002). Thus, the compliance time of 24 months after the effective date
of this AD for the inspection to determine whether the rotary solenoids
are in the correct position, as stated in paragraph (c) of this AD, is
consistent with the compliance time specified in the French
airworthiness directives. We have made no change to this AD.
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
We estimate that 9 Model A330 series airplanes of U.S. registry
will be affected by this AD, that it will take approximately 4 work
hours per airplane to accomplish the required inspection, and that the
average labor rate is $65 per work hour. Based on these figures, the
cost impact of this AD on U.S. operators is estimated to be $2,340, or
$260 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.
Currently, there are no affected Model A340-200 or -300 airplanes
on the U.S. Register. However, if an affected airplane is imported and
placed on the U.S. Register in the future, it will be subject to the
same costs stated above for the Model A330 series airplanes.
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

Adoption of the Amendment
0
Accordingly, pursuant to the authority delegated to me by the
Administrator, the Federal Aviation Administration amends part 39 of
the Federal Aviation Regulations (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. Section 39.13 is amended by adding the following new airworthiness
directive:
2004-23-13 Airbus: Amendment 39-13868. Docket 2003-NM-277-AD.
Applicability: Model A330, A340-200, and 340-300 series
airplanes; certificated in any category; equipped with a ram air
turbine (RAT) module, Model ERPS06M, having part number (P/N)
766351, 768084, 770379, 770952, or 770952A; and containing RAT
actuator P/N 5911905, 5911326, or 5913234.
Compliance: Required as indicated, unless accomplished
previously.
To prevent failure of the RAT actuator to deploy when necessary
during flight, which could result in reduced controllability of the
airplane, accomplish the following:
Service Bulletin Reference
(a) The term ``service bulletin,'' as used in this AD, means the
Accomplishment Instructions of the service bulletins listed in
paragraphs (a)(1) and (a)(2) of this AD. Although these service
bulletins specify returning removed actuators to Liebherr-Aerospace
for inspection, this AD does not require this action.
(1) For Model A330 series airplanes: Airbus Service Bulletin
A330-29-3083, dated August 6, 2002.
(2) For Model A340-200 and -300 series airplanes: Airbus Service
Bulletin A340-29-4064, Revision 01, dated August 8, 2002.
Note 1: The service bulletins refer to Hamilton Sundstrand
Service Bulletin ERPS06M-29-16, dated July 18, 2002; and Liebherr-
Aerospace Service Bulletin 1560A-29-03, dated July 8, 2002; as
additional sources of service information for identifying and
inspecting subject RAT actuators, determining whether inspection
findings are within acceptable limits, and re-identifying actuators
if necessary. Although the Liebherr-Aerospace service bulletin
specifies completing and returning a sheet recording compliance with
that service bulletin and returning removed actuators for
inspection, this AD does not require these actions.
Serial Number Inspection
(b) Within 24 months after the effective date of this AD,
inspect the RAT actuator to determine its serial number (S/N), per
the applicable service bulletin. If the RAT actuator has a S/N
greater than 1286, re-identify the RAT actuator, per the applicable
service bulletin.
Inspection To Determine Position of Rotary Solenoids
(c) If the RAT actuator has a S/N less than or equal to 1286:
Within 24 months after the effective date of this AD, perform a one-
time detailed inspection of the RAT actuator to determine whether
the rotary solenoids are in the correct position, per the applicable
service bulletin.
(1) If the position of the rotary solenoids is within the limits
specified in the applicable service bulletin: Before further flight,
re-identify the RAT actuator, per the applicable service bulletin.
(2) If the position of the rotary solenoids is outside the
limits specified in the applicable service bulletin: Before further
flight, replace the RAT actuator with a new or serviceable actuator,
per the applicable service bulletin.
Note 2: For the purposes of this AD, a detailed inspection is
defined as: ``An intensive visual examination of a specific
structural area, system, installation, or assembly to detect damage,
failure, or irregularity. Available lighting is normally
supplemented with a direct source of good lighting at intensity
deemed appropriate by the inspector. Inspection aids such as mirror,
[[Page 67052]]
magnifying lenses, etc., may be used. Surface cleaning and elaborate
access procedures may be required.''
Parts Installation
(d) As of the effective date of this AD, no person may install,
on any airplane, a RAT actuator having P/N 5911905, 5911326, or
5913234, unless the actions required by this AD are accomplished.
Alternative Methods of Compliance
(e) In accordance with 14 CFR 39.19, the Manager, International
Branch, ANM-116, Transport Airplane Directorate, FAA, is authorized
to approve alternative methods of compliance for this AD.
